INTRODUCTION. Currently, stakeholders across the Russian medical and pharmaceutical community are focusing on the restoration of national pharmaceutical compounding. The Russian pharmaceutical compounding market, with its great potential for growth, requires highly qualified professionals able to ensure the operation of compounding pharmacies and the proper quality of extemporaneous medicinal products. The effectiveness of training for such specialists can be improved by analysing the experience of educational institutions in countries with developed pharmaceutical compounding systems.AIM. This study aimed to analyse the distinguishing features of training for pharmaceutical compounding specialists, as well as determine the main trends in pharmaceutical compounding education in leading international academic institutions.MATERIALS AND METHODS. The study used methods of logical, comparative, structural, and content analysis. The analysis covered 106 pharmacy and pharmacology curricula of the top-25 higher education providers from the QS World University Rankings by Quacquarelli Symonds. The curricula were analysed using open data published online, particularly, on the official websites of the selected universities.RESULTS. The article presents the distinguishing features of pharmaceutical compounding education at different academic qualification levels; these features include the requirements for applicants, time to degree, competence standards, structure of exams, and specifics of students’ professional engagement, with consideration of the national context. The key trends in the education of specialists in pharmaceutical compounding include a decrease in training time for mid-level specialists; a tendency towards concentrating on clinical disciplines due to the expansion of the roles of pharmacy professionals; a growing focus on specialisation in the areas of paediatric, dental, sterile, veterinary, radiopharmaceutical, and orphan drug compounding; increasing use of simulated practice experiences and online learning technologies; and the development of continuing professional education systems.CONCLUSIONS. Pharmaceutical education programmes of leading international educational organisations include disciplines related to extemporaneous compounding. Current international trends—pharmaceutical education with further specialisation in extemporaneous compounding, integration of simulation technologies and online learning into the educational process, and development of continuing professional education—coincide with the development directions of pharmaceutical education in the Russian Federation. Whereas international pharmacy specialists complete additional professional education programmes to gain an additional specialisation in the extemporaneous preparation of paediatric medicinal products, sterile dosage forms, chemotherapy products, radiopharmaceuticals, veterinary products, and dental products, Russian specialists can acquire these additional competencies through further education programmes at the levels of advanced training and residency.

INTRODUCTION. National pharmacy compounding is a priority for providing the population with medicinal products, particularly the medicinal products lacking in the Russian Federation. Investigating opportunities to improve the operation of compounding pharmacies in the Russian Federation remains essential, especially in the context of the developing personalised approach to treatment, growing practice of orphan drug development, and import substitution needs.AIM. This study aimed to identify the factors driving the development of compounding pharmacies under the current conditions.MATERIALS AND METHODS. The study focused on the Russian regulatory framework for pharmacy compounding, as well as the range of dosage forms and administration routes of the medicinal products that had been produced and packaged by the compounding pharmacies in Irkutsk in 2021–2023.RESULTS. This study showed a demand for compounded medicinal products among both healthcare providers and patients. These medicinal products covered a traditional range of compounded medicines, including custom formulae, medicines for paediatrics and geriatrics, stock preparations, and pharmacy-packaged items. In 2021–2023, the mean annual production of Irkutsk pharmacy organisations amounted to ~500,000 units of compounded medicinal products, with a variety of doses and dosage forms. The medicinal products were compounded using ~100 different active substances and over 20 approved medicinal products. This study examined the evolution of Russian pharmacy compounding legislation. The key aspects included the establishment of a pharmaceutical quality system for compounded medicinal products, the extension of shelf life for specific dosage forms, and the authorisation to use medicinal products approved in the Eurasian Economic Union in compounding. The study showed that the main factors driving the operation of compounding pharmacies were the ongoing regulatory framework transformation and the transition from standardised treatment to personalised medicine. The main impediments for compounding pharmacies included the lack of state support, the ban on compounding medicinal products produced by pharmaceutical companies, the shortage of skilled staff, the inadequate supply of equipment (first of all, production machinery), the poor availability of active substances and excipients in small packages, and the challenges associated with regulatory control and oversight over the quality of compounded medicinal products.CONCLUSIONS. Further stimulation of the active development of compounding pharmacies requires further investigation into their operation in other regions, which will help to develop legal arrangements for the federal and regional state support of compounding pharmacies, procure up-to-date materials and equipment, and train the staff for compounding pharmacies.

Even though, nowadays, most medicines are manufactured industrially, patients may have medical needs that can only be met by a tailor-made approach. This requires the availability of pharmacy preparations made under Good Manufacturing Practice (GMP) conditions. An efficient hand hygiene practice is essential herewith, especially if sterile products that are prepared in a cleanroom are concerned. The effectiveness of hand washing and hand disinfection procedures greatly relies on adequate training. We carried out an observational cross-sectional pilot study aimed at optimizing hand hygiene training with objective and measurable quality assessments using an ultraviolet (UV) dye. Practical acceptance criteria for qualifying personnel through this method were set and evaluated. In total, 25 GMP-qualified cleanroom operators washed and disinfected their hands with UV dye hand wash lotion and UV dye hand alcohol, respectively. To obtain a proof-of-concept, the results were judged based on adherence to the WHO six-step protocol and associated acceptance criteria. Commonly missed areas were brought to light, and the influence of procedure duration was investigated. UV-dye-based assessments appeared to be more valuable in hand disinfection than in hand washing. In both procedures, the back of the hands and the thumbs were frequently missed. This underpins the need for enhanced and repeated education on hand washing and disinfection. Additionally, a dry skin gave rise to extra cleaning challenges. From this pharmacy practice pilot study with a focus on pharmaceutical product care, it may be concluded that the application of UV-dye-based assessments offers valuable insights for pharmacists to optimize hand hygiene, thereby increasing the safety of tailor-made medicines and on-site preparations.

Industrially fabricated medicines have a well-defined shelf life supported by rigorous studies before their approval for commercialization. However, the shelf life of extemporaneous compounding topical formulations prepared at hospitals tends to be shorter, especially when no data are available to prove a longer stability period. Also, the storage conditions are unknown in many circumstances. Accelerated Predictive Stability (APS) studies have been shown to be a useful tool to predict in a faster and more accurate manner the chemical stability of extemporaneously compounded formulations requiring a minimum amount of formulation, thereby reducing the chemical drug waste per study. Shelf life will be allocated based on scientific data without compromising drug efficacy or safety. In this work, the APS approach was applied to the commercially available Cristalmina® (CR) and an extemporaneously compounded formulation of chlorhexidine (DCHX). A different degradation kinetic was found between DCHX and CR (Avrami vs. zero-order kinetics, respectively). This can explain the different shelf life described by the International Council for Harmonisation of Technical Requirements Registration Pharmaceuticals Human Use (ICH) conditions between both formulations. A predicted stability for the DCHX solution was obtained from the extrapolation of the degradation rate in long-term conditions from the Arrhenius equation. The estimated degradation from the Arrhenius equation for DCHX at 5 °C, 25 °C, and 30 °C at 365 days was 3.1%, 17.4%, and 25.9%, respectively. The predicted shelf life, in which the DCHX content was above 90%, was 26.67 months under refrigerated conditions and 5.75 and 2.24 months at 25 and 30 °C, respectively. Currently, the Spanish National Formulary recommends a shelf life of no longer than 3 months at room temperature for DCHX solution. Based on the predicted APS and confirmed by experimental long-term studies, we have demonstrated that the shelf life of DCHX extemporaneously compounded formulations could be prolonged by up to 6 months.

Background: Extemporaneous compounding is practiced globally by pharmacists to allow for dispensing of personalised doses of medicinal products not commercially available. Extemporaneous compounding must result in a product which is safe and effective. However, data on formulation and expiry of extemporaneous products may not be readily available. Pharmacists access various resources including compounding databases to obtain information on composition, preparation, and expiry of extemporaneous preparations. Objectives: The aim of this study was to evaluate the type and frequency of extemporaneous compounding in hospital and community pharmacies in the Republic of Ireland (ROI) and to obtain contemporary information on compounding practices and resources used. Methods: All community and hospital pharmacists registered with the Pharmaceutical Society of Ireland, were invited to participate in an on-line survey. The study was approved by the Royal College of Surgeons in Ireland (RCSI) research ethics committee. Results: A total of 202 pharmacists responded to the survey, of which 145 were community-based, 52 hospital-based, and 5 practicing in both. On average, hospital and community pharmacists (n = 138) dispensed

Objective: This study aimed to assess the diversity of extemporaneous preparations, identify the prevalent formulations, and highlight the challenges and opportunities for standardization and improvement of extemporaneous preparation practices. Methods: A survey was conducted among 88 Thai hospitals representing the public and private sectors. The questionnaire gathered information on general hospital characteristics, detailed aspects of extemporaneous compounding, and the specific extemporaneous formulations used. Results: The survey revealed significant variations in extemporaneous preparations among Thai hospitals, with oral liquids, semisolids, and eye preparations commonly employed. The primary oral liquid formulations used were suspensions, syrups, and solutions. Specific medications frequently used in extemporaneous preparations were also identified. The challenges encompassed space, personnel, skills, raw materials, equipment, standardized formula information, preparation process information, funding, and other factors. Conclusion: A survey among Thai hospitals revealed significant variations in extemporaneous preparations in 88 participating hospitals. Common formulations used in extemporaneous compounding include oral liquid preparations, such as suspensions, syrups, solutions, semisolid preparations, and eye preparations. Stakeholder involvement, implementation of standardized operating procedures, resource allocation, comprehensive training programs, and collaboration among hospitals, pharmaceutical companies, and regulatory agencies are recommended to enhance extemporaneous compounding practices.

Introduction: Dabrafenib and trametinib are oral targeted agents indicated for BRAF mutated non-small cell lung cancer and melanoma. There is little data to support the administration of these two agents via enteral feeding tube. This case series describes three patients who received compounded dabrafenib and trametinib suspensions through enteral feeding tubes. Case report: We present three patients who required dabrafenib and trametinib to be prepared as a non-standard compound for the medications to be administered via feeding tube. The patients were diagnosed with with BRAF mutated cancers including melanoma, non-small-cell lung carcinoma, and anaplastic thyroid cancer. In all three cases, there was evidence of initial disease response on imaging, and there were no unexpected toxicities secondary to dabrafenib and trametinib. Discussion: There are patients that are unable to tolerate medications by mouth due to dysphagia, anatomical malfunctions, or other digestive disorders. There is limited literature that describes preparation of trametinib and dabrafenib into an enteral suspension. Identifying a safe and efficacious method of administering these two medications via feeding tube ensures that these patients continue to be able to receive them as part of their anti-cancer therapy. Conclusion: Despite the lack of available data, compounding of dabrafenib and trametinib may be clinically appropriate when benefits outweigh the risk of unconventional administration. Further studies are warranted to assess for the pharmacokinetics, pharmacodynamics, stability, and storage for these liquid medications. [ABSTRACT FROM AUTHOR]

Diazoxide is a potential candidate for the treatment of transitional hypoglycaemia in infants. A clinical trial is currently underway to investigate whether low-dose oral diazoxide is beneficial for severe or recurrent transitional neonatal hypoglycaemia (the NeoGluCO Study, registration ANZCTR12620000129987). The present study aimed to develop and validate the parameters for quantifying diazoxide from neonatal plasma samples, and to assess the stability of extemporaneously prepared diazoxide suspensions to support the NeoGluCO Study. To determine the plasma concentration of diazoxide, a protein precipitation mediated extraction protocol was developed, which demonstrated >94% diazoxide extraction recoveries from all samples. The method was linear over the range of 0.2–40 μg/mL (R2 > 0.9994) with a limit of quantification of 0.2 μg/mL. Accuracy of the method was within 97–106% with relative standard deviation

Due to COVID-19 movement restrictions, institutes of higher learning had to deliver pharmacy curricula remotely. One major challenge was teaching practical lab skills, such as extemporaneous compounding, remotely due to the need for hands-on learning and its associated logistical requirements. We present the approach to remote extemporaneous compounding teaching taken by three pharmacy schools: Monash University Malaysia, University of Michigan, and University of Maryland. Prior to delivery, students were either supplied with or asked to procure a set of easily accessible ingredients and equipment to conduct the extemporaneous practicals from home. We conducted lessons remotely using both synchronous and asynchronous delivery, and demonstrated, taught, and assessed practical lab skills using video conferencing modalities. We successfully conducted remote teaching of extemporaneous compounding, where similar learning outcomes to the face-to-face implementation were achieved. At Monash University Malaysia, > 90% of students responding to the post-activity surveys found the remote extemporaneous sessions useful for their learning, and qualitative comments supported these views. Mean scores from the remote extemporaneous labs in 2021 were similar to those when conducted physically in 2019, supporting the effectiveness of the approach. The different approaches attempted by the three institutions highlighted the flexibility in implementation that can be considered to achieve similar outcomes. Combining technology-based approaches with synchronous and asynchronous teaching and learning methods can successfully deliver extemporaneous compounding skills remotely. [ABSTRACT FROM AUTHOR]

Venetoclax is a potent oral oncology drug (OOD) frequently used to treat hematologic cancers due to its convenience and high efficacy. However, some patients cannot tolerate solid oral formulations, requiring a reformulated version of venetoclax for effective administration. Currently, there is limited information in the literature regarding the extemporaneous compounding of venetoclax.We present our institution's medication use process (MUP) for preparing compounded suspensions of venetoclax for patients with dysphagia who cannot tolerate solid oral formulations. This report has two main aims: to review our MUP from design to implementation, illustrated with real patient cases, and to present it as a strategy for administering venetoclax-based therapies to patients with dysphagia or feeding tubes. From February 2020 to January 2024, 17 patients received venetoclax through the standard MUP, with four developing tumor lysis syndrome (TLS). This study describes their clinical courses and evaluates their responses to the compounded suspensions, considering the uncertain effects of venetoclax prepared through this method.The four patients received venetoclax suspensions during hospitalization due to swallowing difficulties or nutritional support needs. We prepared extemporaneous venetoclax suspensions to ensure continuous therapy, thus avoiding treatment interruptions. TLS was managed using rasburicase and prophylactic allopurinol.The clinical outcomes indicate that the current MUP provides a practical approach to administering venetoclax for dysphagic patients. However, additional research is needed to determine if there are pharmacokinetic differences in the bioavailability of venetoclax between oral and enterally delivered formulations. Further studies will help inform best practices for patient care. [ABSTRACT FROM AUTHOR]

The treatment of respiratory infections in children requires special attention, since the paediatric population has rather specific characteristics and consists of heterogenous subgroups. In this context, the choice of a suitable drug dosage form is of particular importance, depending on the active substance properties, along with the age and general condition of a paediatric patient. The most commonly used pharmaceutical products for respiratory infections in children include oral, parenteral and inhalation dosage forms, although a large number of drugs are not available in a suitable dosage form and/or strength for paediatric age, leading to the frequent use of unauthorized drugs (i.e., unlicensed use). Other important issues that should be considered when choosing the appropriate paediatric dosage form and/or compounding procedure are related to the careful considerations of the pharmaceutical product composition (safety of excipients) and the choice of administration/dosing device in relation to a child's age. This paper provides an overview of paediatric dosage forms used in the treatment of respiratory infections in children, their benefits and limitations. The review includes examples of various pharmaceutical products, along with the considerations regarding administration/dosing devices. Specific characteristics of paediatric populations affecting the decision on the choice of age-appropriate paediatric formulation are also addressed.

The International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH), along with the World Health Organization (WHO), has provided a set of guidelines (ICH Q1A-E, Q3A-B, Q5C, Q6A-B) intended to unify the standards for the European Union, Japan, and the United States to facilitate the mutual acceptance of stability data that are sufficient for registration by the regulatory authorities in these jurisdictions. Overall, ICH stability studies involve a drug substance tested under storage conditions and assess its thermal stability and sensitivity to moisture. The long-term testing should be performed over a minimum of 12 months at 25 °C ± 2 °C/60% RH ± 5% RH or at 30 °C ± 2 °C/65% RH ± 5% RH. The intermediate and accelerated testing should cover a minimum of 6 months at 30 °C ± 2 °C/65% RH ± 5% RH (which is not necessary if this condition was utilized as a long-term one) and 40 °C ± 2 °C/75% RH ± 5% RH, respectively. Hence, the ICH stability testing for industrially fabricated medicines is rigorous and tedious and involves a long period of time to obtain preclinical stability data. For this reason, Accelerated Predictive Stability (APS) studies, carried out over a 3–4-week period and combining extreme temperatures and RH conditions (40–90 °C)/10–90% RH, have emerged as novel approaches to predict the long-term stability of pharmaceutical products in a more efficient and less time-consuming manner. In this work, the conventional ICH stability studies versus the APS approach will be reviewed, highlighting the advantages and disadvantages of both strategies. Furthermore, a comparison of the stability requirements for the commercialization of industrially fabricated medicines versus extemporaneous compounding formulations will be discussed.

Objective This study examined how undergraduate students, graduate interns and registered pharmacists perceived their competence in extemporaneous compounding. Methods A cross-sectional observational study was conducted using a self-administered survey and participants ranked how confident they felt about compounding certain products using a Likert's scale and free-text responses. Key findings Pharmacy students perceived to be as confident as the interns and pharmacists in preparing 'simple' products, such as solutions, suspensions, creams and ointments. A lack of frequent practice was related to poor confidence by all three groups. Conclusion Integration of theoretical, legal and ethical and patient counselling aspects in extemporaneous compounding curriculum could enhance learning and outcomes. [ABSTRACT FROM AUTHOR]

There is a need to develop dosage forms suitable for children to improve drug treatment. Extemporaneous compounding of drugs for children is one way to meet these needs. However, excipients generally considered as safe in adults may not be appropriate in dosage forms intended for children. The aim was to optimize the composition of two pediatric liquid preparations by substituting paraben as a microbiological preservative and ethanol as a solubilizer, with excipients more suitable for pediatric use. The oral liquids were Naloxone 1 mg/mL and Propranolol 10 mg/mL. Twelve different formulations were tested with propranolol and naloxone, respectively, during the screening process to select appropriate formulations. Sodium benzoate and glycerol were used as a preservative and solubilizer, respectively, and different pH of the formulations were evaluated. The formulations were characterized according to dispensed dose (dosing accuracy), viscosity and osmolality. The optimized formulations from the screening process were tested with two amounts of sodium benzoate and microbiological assays were performed. These formulations were shown to have satisfactory preservative properties and dosing accuracy. The results showed that the oral liquids could be prepared without the addition of solubilizer and with lower osmolality (naloxone), thus reducing the risk of gastrointestinal side effects.

Introduction: Acute promyelocytic leukemia (APL) is a potentially curable malignancy with 4-year overall survival rates >90%. Early complications from the disease or its treatment may result in a loss of oral access and require alternative administration of medications. Tretinoin has been the backbone of APL therapy since the late 1990s and is only available as a liquid filled capsule. Case report: Two patients with high-risk APL were unable to safely swallow tretinoin capsules due to complications of their disease. Management & outcome: We prepared a tretinoin slurry using tretinoin 10 mg capsules, sterile water, and mineral oil at a ratio of 1 capsule to 2.75 mL sterile water to 1.25 mL mineral oil. This was successfully administered to both patients and no doses of tretinoin slurry were missed by either patient. In the patient who has long-term follow up available, a complete remission was achieved. Discussion: Due to tretinoin's known teratogenicity, this capsule should not be crushed, cut, or open, which limits its use in patients without oral access. Alternative routes of administration, such as via a nasogastric tube or sublingually, have not been safe and effective. By preparing a tretinoin slurry in our hazardous extemporaneous compounding area, we were able to safely and effectively prepare a tretinoin slurry that was successfully administered to two patients. This alternative preparation did not alter long-term outcomes and represents a viable option for patients who do not have oral access. [ABSTRACT FROM AUTHOR]

Background: Baclofen is prescribed for both adults and children as a muscle relaxant, but no data exists to support an appropriate lower‐dose extemporaneously compounded oral liquid suitable for young children in New Zealand. Aim: This study aimed to determine the stability of 1 mg/mL baclofen oral suspension over 30 days. Method: Baclofen suspensions were compounded (n = 6 per formulation) using suspending vehicles Ora‐Blend® (OB) or Ora‐Blend sugar‐free® (OB SF) and stored at either 25°C/60% relative humidity or 2–8°C for 30 days. Organoleptic properties, sedimentation volume ratio, ease of redispersion, pH and baclofen content were determined. Results: Formulations required 2–3 inversions to redisperse at each time point. A colour change was observed from day 14 in the OB suspensions stored at both temperatures, likely due to the Maillard reaction, whereas no colour change was observed in any OB SF suspensions. The pH of all formulations remained between 4.5 and 4.6. Both OB and OB SF suspensions retained >90% of the initial baclofen concentration over 30 days. Conclusion: Although baclofen 1 mg/mL suspensions prepared in both OB and OB SF retained sufficient baclofen to be considered chemically stable in both storage conditions over the study period, OB SF is recommended as a preferred vehicle over OB formulations due to the colour change observed.

Abstract Background Pharmaceutical compounding is an essential component in pharmacy practice allowing pharmacists to provide dosage forms or strengths that are commercially unavailable. Medications compounded for patient-specific needs contribute to personalized medicine. Extemporaneous compounding provided by pharmacies overcomes the market shortage of these therapeutic products. The aim of this study is to investigate and characterize the prevalence, characteristics, and determinants of extemporaneous compounding in Jordanian pharmacies. Methods This study was based on a cross-sectional questionnaire and included 431 randomly selected pharmacies in the twelve governorates of the country. Data were collected via face to face interviews of pharmacists who voluntarily and verbally responded to the questions. Results Results revealed that 223 (51.7%) of the surveyed pharmacies practiced extemporaneous compounding. The main reason for not providing extemporaneous compounding services was lack of prescription orders for compounded preparations (53.8%). The second reason was lack of the equipment and supplies necessary for compounding (24.4%). Extemporaneous compounding prescriptions were mainly issued by dermatologists (98.2%); dermatological indication was the most common of all extemporaneous compounded prescriptions. The main reason for requesting compounded medications was the lack of a commercially available product (87.9%). The vast majority of the compounded dosage forms were creams (99.6) and ointments (91.5), followed by solutions (23.3%). Only 5 (2.2%) of the studied compounding pharmacies prepared sterile products. The major sources for compounding protocols were the physician order (94.2%), and ‘in-house’ protocols (44.8%). However, the main resource for estimating compounded medications expiration date was information based on pharmacist’s experience (57.8%) and the physician’s order (53.4%). Conclusions Extemporaneous compounding is a common element of pharmaceutical care. Topical preparations are the most commonly compounded products. Finding from this study suggest that there is a need for standardizing the compounded product formularies, product quality testing, and improving the consistency in estimation of an expiration date of compounded products.

OBJECTIVES Some drugs need to be compounded by the pharmacist before being administered to the patient. A study was conducted to determine the stability of acetazolamide suspensions in 2 different vehicles (Oral Mix and Oral Mix Sugar Free [SF]) from bulk drug and tablets at 2 different temperatures and in 2 different containers (amber plastic bottles and clear plastic syringes). METHODS Acetazolamide suspensions (25 mg/mL) were prepared from bulk drug or tablets. Each suspension, using Oral Mix or Oral Mix SF, was split between 2 types of containers--amber plastic bottles and clear plastic syringes--and stored either at room temperature (23°C--27°C) or under refrigeration (3°C--7°C). Samples were drawn from the suspensions right after preparation and on days 7, 14, 30, 45, 60, 75, and 90. They were then analyzed by high-performance liquid chromatography (HPLC) using a reverse- phase column. A validated stability-indicating HPLC with ultraviolet detection method was developed. A visual inspection and a pH measurement were also completed at each time point. Stability was defined as retention of at least 90% of the initial concentration of acetazolamide suspension. RESULTS At least 91.2% of the initial acetazolamide concentration in suspensions remained throughout the 90-day study period for both vehicles, both containers, and both temperatures. Assays varied between 91.2% and 105.0% of the initial concentration for all 112 tested conditions but 2 (105.2% and 109.0%). Linear regression was calculated for each time profile and remained above 95.0% at the end of the study in all cases. Similarly, pH remained within 0.1 unit of the initial pH, which was 4.2 for Oral Mix and 4.3 for Oral Mix SF. Furthermore, no changes in organoleptic properties were observed because the preparations remained as white fluid suspensions without sedimentation. CONCLUSIONS Acetazolamide suspensions were stable for at least 90 days in all tested conditions because the average drug concentration was not less than 90% of the initial concentration. The beyond-use date could be extended from 60 to 90 days. [ABSTRACT FROM AUTHOR]

Background: Levofloxacin is a broad‐spectrum antibiotic of the fluoroquinolone class used in the paediatric population to treat resistant bacterial infections. Because no commercial option exists, a stable liquid formulation of this antibiotic made with accessible vehicles would be useful. Aim: The aim of this study was to develop and assess the stability of levofloxacin suspensions made from commercially available tablets and three different accessible vehicles. Methods: Levofloxacin suspensions (50 mg/mL) were compounded using two different commercially available tablets (from Apotex; Toronto, ON, Canada and Sandoz; Boucherville, QC, Canada) and three different vehicles (Ora‐Blend, Oral‐Mix; Medisca, Saint‐Laurent, QC, Canada and Simple Syrup (SS); Laboratoire Atlas Inc., Anjou, QC, Canada). Suitable suspensions in Ora‐Blend and Oral‐Mix were stored at room temperature (25°C) as well as under refrigeration (5°C) in amber plastic bottles for 90 days. Suspensions made with SS were only stored at 25°C because of sugar crystallisation at 5°C. Suspension concentrations were assessed by HPLC. Results: Suspensions using Apotex levofloxacin tablets produced unsuitable high‐foaming, phase‐separated, non‐homogeneous suspension products in all vehicles tested that were therefore not tested for stability. Levofloxacin suspensions prepared using Sandoz tablets remained chemically and physically stable for 3 months, with >96% recovery according to United States Pharmacopeia criteria (90%–110%) in all three vehicles. Conclusion: The results show that the choice of generic levofloxacin tablets is important when preparing homogeneous suspensions. All three vehicles could be used to prepare levofloxacin suspensions using Sandoz tablets that were physically and chemically stable for 3 months. [ABSTRACT FROM AUTHOR]

Background: Pharmaceutical compounding is an essential component in pharmacy practice allowing pharmacists to provide dosage forms or strengths that are commercially unavailable. Medications compounded for patient-specific needs contribute to personalized medicine. Extemporaneous compounding provided by pharmacies overcomes the market shortage of these therapeutic products. The aim of this study is to investigate and characterize the prevalence, characteristics, and determinants of extemporaneous compounding in Jordanian pharmacies.Methods: This study was based on a cross-sectional questionnaire and included 431 randomly selected pharmacies in the twelve governorates of the country. Data were collected via face to face interviews of pharmacists who voluntarily and verbally responded to the questions.Results: Results revealed that 223 (51.7%) of the surveyed pharmacies practiced extemporaneous compounding. The main reason for not providing extemporaneous compounding services was lack of prescription orders for compounded preparations (53.8%). The second reason was lack of the equipment and supplies necessary for compounding (24.4%). Extemporaneous compounding prescriptions were mainly issued by dermatologists (98.2%); dermatological indication was the most common of all extemporaneous compounded prescriptions. The main reason for requesting compounded medications was the lack of a commercially available product (87.9%). The vast majority of the compounded dosage forms were creams (99.6) and ointments (91.5), followed by solutions (23.3%). Only 5 (2.2%) of the studied compounding pharmacies prepared sterile products. The major sources for compounding protocols were the physician order (94.2%), and 'in-house' protocols (44.8%). However, the main resource for estimating compounded medications expiration date was information based on pharmacist's experience (57.8%) and the physician's order (53.4%).Conclusions: Extemporaneous compounding is a common element of pharmaceutical care. Topical preparations are the most commonly compounded products. Finding from this study suggest that there is a need for standardizing the compounded product formularies, product quality testing, and improving the consistency in estimation of an expiration date of compounded products.

Oral liquid formulations are compounded by pharmacists to meet the needs of patients when a suitable commercially available product is not available. To minimize the errors associated with measuring multiple excipients and to enhance the shelf-life of the medicines, commercially available suspending bases are commonly used. This review aims to compare the stability and shelf life of commercially available extemporaneous formulation to traditional formulation methods. Five (5) databases were searched (Pubmed, SCOPUS, Science direct, Embase, and EBSCOhost). Twelve articles, comprising of seven cardiovascular medications (amiodarone, captopril, carvedilol, furosemide, nifedipine, sotalol, and valsartan), met the study inclusion criteria and were reviewed. Chemical stability of the drugs was comparable between the two formulation methods except for furosemide, captopril, and valsartan. The traditional compounding method provided superior stability for furosemide (90 vs. 14 days) and captopril (50 vs. 14 days), while the commercial vehicles provided superior stability for valsartan (90 vs. 14 days). Physical stability tests indicated that sedimentation does occur with both formulation methods. Microbial studies within the data were lacking and further research can be undertaken in this area. This review highlights the importance of assessing the suitability of compounding ingredients prior to preparation of the formulation. [ABSTRACT FROM AUTHOR]

Extemporaneous compounding is one of traditional drug prescribing methods. Although this compounding is still used until present days, but it remains problems since many unexpected cases happen such as medication error, quality of the compounding and also bacterial contamination that may appear in each compounding dosage. This study aims to determine prescribing pattern of antibiotic on dosage of extemporaneous compounding suspension in primary health care centers. The employed method is cross sectional survey conducted in 24 primary health care centers; it is obtained 87 extemporaneous compounding suspensions containing antibiotics. The result shows the antibiotics frequently used in the compounding in the primary health care centers are amoxicillin (90.62%) in form of tablet dosage (10.42) and suspension dosage (89.58%). The most used pattern of antibiotic prescribing in dosage of extemporaneous prescribing suspension is antibiotic suspension + anti-histamine tablets + corticosteroids tablet (18.39%). It can be concluded that the most used prescribing pattern of antibiotic in dosage of extemporaneous prescribing suspension is antibiotic suspension + anti-histamine tablets + corticosteroids tablet.

Extemporaneous oral liquid preparations are commonly used when there is no commercially available dosage form for adjustable dosing. In most cases, there is a lack of stability data to allow for an accurately assigned shelf life and storage conditions to give greater confidence of product safety and efficacy over its shelf life. The aim of this study was to evaluate the physical, chemical and microbiological stability of an extemporaneous oral liquid suspension of losartan potassium, 5 mg/mL, used to treat paediatric hypertension in Our Lady’s Children’s Hospital Crumlin, Ireland. The losartan content of extemporaneous oral suspensions, prepared with and without addition of water, was measured by UV and confirmed by HPLC analysis. Suspensions were stored at 4 °C and room temperature (RT) and were monitored for changes in; pH, colour, odour, re-dispersibility, Total Aerobic Microbial Count, Total Yeast and Mould Count and absence of E. coli. Results showed that suspensions prepared by both methods, stored at 4 °C and RT, were physically and microbiologically stable over 28 days. Initial losartan content of all suspensions was lower than expected at 80–81% and did not change significantly over the 28 days. HPLC and NMR did not detect degradation of losartan in the samples. Suspensions prepared in water showed 100% losartan content. The reduced initial losartan content was confirmed by HPLC and was related to the acidic pH of the suspension vehicle. Physiochemical properties of the drug are important factors for consideration in the selection of suspension vehicle for extemporaneous compounding of oral suspensions as they can influence the quality, homogeneity and efficacy of these preparations.

Background: Extemporaneous compounding is practiced globally by pharmacists to allow for dispensing of personalised doses of medicinal products not commercially available. Extemporaneous compounding must result in a product which is safe and effective. However, data on formulation and expiry of extemporaneous products may not be readily available. Pharmacists access various resources including compounding databases to obtain information on composition, preparation, and expiry of extemporaneous preparations., Objectives: The aim of this study was to evaluate the type and frequency of extemporaneous compounding in hospital and community pharmacies in the Republic of Ireland (ROI) and to obtain contemporary information on compounding practices and resources used., Methods: All community and hospital pharmacists registered with the Pharmaceutical Society of Ireland, were invited to participate in an on-line survey. The study was approved by the Royal College of Surgeons in Ireland (RCSI) research ethics committee., Results: A total of 202 pharmacists responded to the survey, of which 145 were community-based, 52 hospital-based, and 5 practicing in both. On average, hospital and community pharmacists ( n  = 138) dispensed <2-10 prescriptions for extemporaneous products per month. Pharmacists reported compounding 13 different types of extemporaneous preparations. Of these, dermatological preparations and oral liquid formulations (OLFs) were most commonly compounded. Extemp.ie, an Irish compounding database, was the most frequently used resource for compounding guidance and product expiry., Conclusions: The results of this study show that extemporaneous compounding is still practiced in hospital and community pharmacies in the ROI. The limited response of 4.6% obtained may reflect that extemporaneous compounding is concentrated in a relatively small number of pharmacies. There remains a clinical need for extemporaneous products in the ROI and extemporaneous compounding continues to be an invaluable skillset for pharmacists., Competing Interests: None., (© 2023 The Authors.)

Diazoxide is a potential candidate for the treatment of transitional hypoglycaemia in infants. A clinical trial is currently underway to investigate whether low-dose oral diazoxide is beneficial for severe or recurrent transitional neonatal hypoglycaemia (the NeoGluCO Study, registration ANZCTR12620000129987). The present study aimed to develop and validate the parameters for quantifying diazoxide from neonatal plasma samples, and to assess the stability of extemporaneously prepared diazoxide suspensions to support the NeoGluCO Study. To determine the plasma concentration of diazoxide, a protein precipitation mediated extraction protocol was developed, which demonstrated >94% diazoxide extraction recoveries from all samples. The method was linear over the range of 0.2-40 μg/mL (R 2  > 0.9994) with a limit of quantification of 0.2 μg/mL. Accuracy of the method was within 97-106% with relative standard deviation < 6% for all samples. Diazoxide-plasma samples were stable for up to three months at -20 °C and up to 48 h when stored in the auto-sampler. Samples were stable for up to two freeze-thaw cycles, with further cycles compromising stability of diazoxide in plasma. The developed method was applied to determine chemical stability of the extemporaneously prepared diazoxide suspensions. These were stable at both 2-8 °C and 25 °C/60% RH, with 98% of diazoxide remaining after 35 days in both storage conditions. Diazoxide was successfully quantified from plasma collected from six neonates enrolled in the NeoGluCO Study, using the developed protocol. Overall, an efficient and reproducible extraction protocol was developed and validated for the estimation of diazoxide from human plasma., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2023 The Authors.)

Purpose: The feasibility of preparing an eslicarbazepine acetate suspension using Aptiom tablets for administration via enteral feeding tubes was evaluated. Methods: Eslicarbazepine acetate suspension (40 mg/mL) was prepared using Aptiom tablets after optimizing the tablet crushing methods and the vehicle composition. A stability-indicating high-performance liquid chromatography (HPLC) method was developed to monitor the eslicarbazepine stability in the prepared suspension. Three enteric feeding tubes of various composition and dimensions were evaluated for the delivery of the suspensions. The suspension was evaluated for the physical and chemical stability for 48 hours. Results: The reproducibility and consistency of particle size reduction was found to be best with standard mortar/pestle. The viscosity analysis and physical stability studies showed that ORA-Plus: water (50:50 v/v) was optimal for suspending ability and flowability of suspension through the tubes. The developed HPLC method was found to be stability indicating and suitable for the assay of eslicarbazepine acetate in the prepared suspension. The eslicarbazepine concentrations in separately prepared suspensions were within acceptable range (±3%), indicating accuracy and reproducibility of the procedure. The eslicarbazepine concentrations in suspensions before and after delivery through the enteric feeding tubes were within acceptable range (±4%), indicating absence of any physical/chemical interactions of eslicarbazepine with the tubes and a successful delivery of eslicarbazepine dosage via enteric feeding tubes. The stability study results showed that eslicarbazepine concentration in the suspension remained unchanged when stored at room temperature for 48 hours. Conclusion: The study presents a convenient procedure for the preparation of a stable suspension of eslicarbazepine acetate (40 mg/mL) using Aptiom tablets, for administration via enteral feeding tubes.

Many children require medications in oral liquid dosage forms when their dose does not conform to a manufactured tablet or capsule size. Liquid medications are also needed for children who are unable to swallow solid dosage forms. This statement from the PPAG is in support of standardizing the concentrations of extemporaneous formulations of liquid medications for the benefits of safety, accuracy, and overall communication between providers.

In this work, it is aimed to determine pharmacists' attitude, level of knowledge on extemporaneous formulations including how accurate the formulations are prepared, the problems pharmacists face during preparation, and their approach to solve problems on extemporaneous preparation. Additionally with this work, we aim to gather data on frequently written extemporaneous prescriptions during the recent years. In this work, a questionnaire with the title of "Evaluation of pharmacy manager's knowledge and attitude on extemporaneous preparation" was applied to pharmacy managers. This questionnaire was completed by 54 community pharmacists. According to our results, it was found that extemporaneous preparations were prescribed to all of the pharmacies that the questionnaire applied, however pharmacists were confronted with various problems during preparation of the formulations.

On October 3, 2016, the U.S. Food and Drug Administration published in theFederal Registeran expanded list of drug products that are not to be used in compounding extemporaneous dosage forms. This list contains numerous analgesic or anti-inflammatory agents and other chemicals sometimes used to manage pain and related symptoms. Because pharmacies are licensed by the states and other jurisdictions (districts, territories) as opposed to the federal government, regulation of extemporaneous compounding is inconsistent across the nation and minimal to nonexistent is some jurisdictions. Clinicians are urged to assure that pharmacies they and their patients use adhere to this list and compound only dosage forms for which there is good evidence of both safety and efficacy.

AIMS:The aims of this study were to explore the extent of extemporaneous compounding in veterinary centres throughout New Zealand and to determine whether pharmacists could collaborate with veterinarians to improve this service in New Zealand. METHODS:Questionnaires were sent to 200 randomly selected veterinarians in New Zealand. Semi-structured interviews were also conducted with selected participants from four animal facilities (zoos, research facilities and animal shelters) and two compounding pharmacies. RESULTS:Of the 200 veterinarian questionnaire recipients, 99 responded. Ten replies were withdrawn from the study giving a response rate of 44.5%. Of these 89, 33 (37%) compounded in their practice. Of the 33 compounding professionals, 3 (9%) compounded daily for animals under their care; 11 (34%) weekly, 18 (54%) monthly and 1 (3%) compounded yearly. Compounding was done by 29/33 (88%) veterinarians, 16/33 (48%) veterinary nurses or 6/33 (18%) others. It was carried out due to the unavailability of commercial products, or the need for dose adjustment to ease administration or improve compliance. The animals most commonly requiring veterinary compounding were dogs (21/33; 64%), cats (19/33; 58%) or cattle (15/33; 46%). Products which were commonly compounded included cyclosporin eye drops, methimazole gels and potassium bromide solutions. Issues commonly faced when compounding included unavailability of dosage forms (18/33; 55%) or appropriate ingredients (14/33; 42%), stability (12/33; 36%), time constraints (10/33; 30%) or unavailability of equipment (9/33; 27%). Reasons given for not compounding included medicines being commercially available (38/56; 68%), pharmacy compounding for those particular practices (24/56; 43%), lack of training (21/56; 38%), ingredients (16/56; 29%) or equipment (15/56; 11%). All participants who worked with a pharmacist (11/33; 33%) described this relationship as beneficial and indicated they would continue to do so in the future. CONCLUSIONS:Veterinary extemporaneous compounding exists in New Zealand. As pharmacists have extensive knowledge in formulating medications and compounding they could be of greater value to veterinarians and their patients. Educating both professions on the opportunities available to them from this collaboration could be an important step forward. CLINICAL RELEVANCE:This study provides new information regarding extemporaneous compounding for veterinary patients in New Zealand. [ABSTRACT FROM AUTHOR]

Abstract: Background: Administration of medications to pediatric patients is challenging because many drugs are not commercially available in appropriate dosage formulations and/or strengths. Consequently, these drugs are prepared extemporaneously as oral liquid (OL) formulations using marketed tablets or capsules. In many cases, the stability of these extemporaneous preparations, which may affect their tolerability, has not been documented. An alternative extemporaneous solid formulation, such as a fast-dispersing tablet (FDT), may offer enhanced stability as well as dosing flexibility because it may be administered as an orodispersible tablet or as a reconstituted suspension/solution. Although FDTs are available increasingly as patient-friendly oral dosage formulations, and their simple method of manufacture can be applied to extemporaneous formulations, such applications have not been explored to date. Objectives: The use of extemporaneous captopril OL formulations in hospitals in Ireland was surveyed, and the stability of the most commonly used captopril formulation (reference) was investigated and compared with that of a newly available extemporaneous FDT formulation. Methods: The survey was carried out in 120 hospitals in the Republic of Ireland. The 56-day stability of the most commonly used formulation was compared with that of a newly available extemporaneous captopril FDT preparation. The captopril content of the formulations was measured by high-performance liquid chromatography analysis. Formulations were also monitored for changes in appearance, including color; odor; and pH (OLs only). Results: The survey showed that extemporaneously prepared captopril OLs were extensively used, particularly in specialist children''s hospitals. The most commonly used preparation was a xanthan gum–based oral suspension. Analysis of these OL preparations showed the OLs to have been stable up to day 7, but that the captopril concentration decreased to 72% to 84% at day 14 and to 59% to 68% at day 56; this decrease was accompanied by a pungent odor suggestive of captopril oxidation. In contrast, FDT formulations demonstrated greater stability, with 96% of captopril present at day 56. Conclusions: The results of this study support only a 7-day stability for the currently dispensed captopril OL in hospitals in Ireland. In contrast, a stability of at least 56 days was shown with the FDTs. The FDTs may represent an alternative and convenient oral solid extemporaneous preparation of captopril and, potentially, other extemporaneous pediatric medications. [Copyright &y& Elsevier]

Many references exist in the literature identifying the usefulness of oxandrolone in treating muscle wasting due to various conditions including severe burns. However, there is an absence of dosage form alternatives as it is only available as tablets. The dose for children is weight based (0.1mg/kg) which is difficult to achieve with the currently available tablets of 2.5mg and 10mg. The literature provides ample evidence of clinical importance but little guidance on extemporaneous oral liquid formulation of oxandrolone. In order to develop and validate an extemporaneous liquid formulation, suspensions of oxandrolone were developed using locally available (New Zealand) vehicles. Combinations of these vehicles with ethanol, as advised in some articles were also tried. Assay method was developed for oxandrolone using High Performance Liquid Chromatography (HPLC) and Mass Spectroscopy (LC–MS). The formulations were evaluated for stability as per the International Conference on Harmonization (ICH) stability guidelines. They were observed for physical and chemical stability at different time points over a period of 28 days. A stable and validated liquid formulation of oxandrolone has been developed which can be made under the hospital and community pharmacy conditions. The formula utilises commercially available oxandrolone tablets, crushed and dispersed in Simple Syrup BP or Orablend® vehicle. The formulation has confirmed stability for 21 days and can be easily made with locally available vehicles. [Copyright &y& Elsevier]

Despite a plethora of pre-packaged topical products produced by the pharmaceutical industry for treating skin diseases, the practice of extemporaneous compounding continues, albeit at a low level (<1% of prescriptions). Sourcing prescription compounding services via the Internet has increased dramatically in recent years, posing new risks to patients and prescribing physicians. The technical, economic, and medico-legal issues associated with the practice of ad hoc compounding are reviewed and updated. A practical set of recommendations are provided for prescribing physicians and their recipient patients with the hope that, if followed, they will reduce the potential risks associated with the use of products that are formulated extemporaneously.

Objective: Recently, a premature neonate, born at 26.5 weeks, was treated with sirolimus for kaposiform hemangioendothelioma with Kasabach-Merritt phenomenon at the University of New Mexico Children's Hospital. Because of the lipophilic properties of the drug and an inability to draw the correct dose needed for the neonate with the standard 1 mg/mL concentration, sirolimus was diluted to 0.01 mg/mL (10 mg/L) in medium-chain triglyceride (MCT) oil. The objective of this study was to evaluate the stability of sirolimus diluted in MCT oil., Methods: Commercially available sirolimus oral solution was diluted with MCT oil from 1 mg/mL to 10 mg/L. The diluted samples were prepared by measuring 0.1 mL of the commercial product in an oral syringe and mixing with 9.9 mL of MCT oil. The 3 diluted samples were placed in amber glass vials, stored at 10°C, and analyzed over 14 days., Results: The initial concentration of the 3 samples ranged from 8.5 to 10.8 mg/L sirolimus, or 85% to 108% of the target value. No significant differences were seen between average concentrations on the days tested. However, the average drug concentration fell to approximately 90% of the theoretical 10 mg/L target concentration between days 7 and 10., Conclusions: This study shows that sirolimus oral solution diluted with MCT oil to a final concentration of 10 mg/L was stable for at least 7 days when stored at 10°C, suggesting that the beyond-use date should be 7 days., Competing Interests: Disclosures.

Background: Extemporaneous compounding (EC) involves the preparation of a therapeutic product for specific patient need. However, there is a potential relationship between this procedure and the occurrence of health incidents (HI). The use of trigger tools increases HI identification., Objective: This study assessed the performance of EC as a trigger to detect potential health incidents arising from this procedure., Methods: A one-month observational and cross-sectional study was performed in internal medicine ward and intensive care unit of medium-sized hospital. Data collection was carried out in 5 stages: all triggered patients with dysphagia or enteral feeding tube with prescription of EC were included; EC executed in prescribed standardized drugs was observed; the procedure was compared with the hospital guide and scientific literature; HI monitoring and their evaluation using WHO and NCC MERP algorithms; a search for pharmaceutical alternatives (PA) that would avoid the observed EC., Results: 197 patients were recruited. Almost half of them were triggered by EC from 84 standardized drugs. 48 patients met the inclusion criteria. 28 adverse drug reactions, 01 therapeutic ineffectiveness, and 29 medication errors were identified. EC as a trigger tool showed a PPV value of 0.38. Only 24 drugs have PA available in the market, which could avoid one third of all observed EC., Conclusion: It was possible to detect potentially HI in one of two patients with enteral feeding tubes using EC as a trigger tool. The use of EC as a trigger tool contributes to identifying potential HI arising from drugs, which have not gotten pharmaceutical alternatives to be administered via enteral feeding tube., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

Extemporaneous oral liquid preparations are commonly used when there is no commercially available dosage form for adjustable dosing. In most cases, there is a lack of stability data to allow for an accurately assigned shelf life and storage conditions to give greater confidence of product safety and efficacy over its shelf life. The aim of this study was to evaluate the physical, chemical and microbiological stability of an extemporaneous oral liquid suspension of losartan potassium, 5 mg/mL, used to treat paediatric hypertension in Our Lady's Children's Hospital Crumlin, Ireland. The losartan content of extemporaneous oral suspensions, prepared with and without addition of water, was measured by UV and confirmed by HPLC analysis. Suspensions were stored at 4 °C and room temperature (RT) and were monitored for changes in; pH, colour, odour, re-dispersibility, Total Aerobic Microbial Count, Total Yeast and Mould Count and absence of E. coli. Results showed that suspensions prepared by both methods, stored at 4 °C and RT, were physically and microbiologically stable over 28 days. Initial losartan content of all suspensions was lower than expected at 80–81% and did not change significantly over the 28 days. HPLC and NMR did not detect degradation of losartan in the samples. Suspensions prepared in water showed 100% losartan content. The reduced initial losartan content was confirmed by HPLC and was related to the acidic pH of the suspension vehicle. Physiochemical properties of the drug are important factors for consideration in the selection of suspension vehicle for extemporaneous compounding of oral suspensions as they can influence the quality, homogeneity and efficacy of these preparations.

Background: Previously, we reported the efficacy of Lichtena® – a phytocosmetic cream product – in atopic dermatitis (AD). Later, fraudulent triamcinolone acetonide (TACA) was detected at low doses (16–40 μg/g) in Lichtena. This suggested that TACA may be effective at much lower concentrations than used in commercial products (1,000 μg/g). Objectives: To investigate the efficacy in AD of low-dose TACA in Lichtena compared to plain Lichtena. Methods: Fourteen patients presenting symmetrical lesions of AD were treated for 1 month with Lichtena plus 25 μg/g TACA (= verum) and plain Lichtena (= placebo). The severity of the lesions was assessed by the Severity Scoring of Atopic Dermatitis (SCORAD) on days 0 (= baseline), 7, 14 and 28. Results: Already after 1 week of treatment, significant SCORAD differences to baseline were observed comparing verum- and placebo-treated areas. No improvement was observed using plain Lichtena. Conclusions: TACA displayed a significant improvement of AD at doses up to 40 times lower than in commercial products. Copyright © 2005 S. Karger AG, Basel [ABSTRACT FROM AUTHOR]
