Heterocyclic compounds with diaryl substituents have been a milestone approach for selective cyclooxygenase 2 (COX 2) inhibition by bioisosteric replacements and modifications. It is also known that thiazole derivatives have different pharmacological activities. In this study, nine novel 2-[(1,5-diphenyl-1H-imidazole-2-yl)thio]-N-(thiazole-2-yl)acetamide derivatives (Compound 1-9) were synthesized via the reaction of 1,5-disubstitued phenyl-imidazole-2-thiole and N-thiazole acetamide. The inhibitory effects of COX-1 and COX-2 enzymes were tested for the synthesized compounds. Enzyme-ligand interactions of the most active compound on COX subtypes were elucidated by molecular modeling studies. The percent inhibitory effect for compound 1, which is the naked derivative among all the compounds, was found to be the most active on COX-2 at 10 mu M concentration (C1(COX-2): 88%, SC-560(COX-2): 98.2%, C1(COX-1): 60.9%); whereas compound 9 showed the highest inhibitory effect and was found to be the most selective derivative on COX-1 isoenzyme (C9(COX-1): 85%, DuP-697(COX-1): 97.2%, C9(COX-2): 57.9%).

- Abstract
Expression of N-glycolyl GM3 (NeuGcGM3) ganglioside was detected in the tumor specimens of patients who were on Racotumomab anti-idiotype vaccine maintenance treatment, and prognostic significance as a biomarker was investigated. No statistically significant association was observed in the multivariate analysis between overall survival and tissue NeuGcGM3 IHC levels. Although numerically there was a difference favoring less intense IHC for better prognosis, this did not reach statistical power. However, there was a strong correlation between Racotumomab doses and overall survival (OS). Mean OS of the patient with more than 10 Racotumomab application was significantly longer than the patient who had less than 10 injections (70.7 months vs. 31.1 months, p<0.001). We propose that, regardless of staining intensity, the presence of NeuGcGM3 in patient tissues might be an indicator of benefit in Racotumomab treatment., NA

Mühendislik ,Kimya - Abstract
A series of 3-hydroxy-6-methyl-2-[(substitutedpiperidine-1-yl)methyl]-4H -pyran-4-one structured compounds were synthesized by reacting 5-hydroxy-2-methyl-4H -pyran-4-one with suitable piperidine derivatives using Mannich reaction conditions. Antibacterial activities of the compounds for E. coli ATCC 25922, S. paratyphi ATCC BAA-1250, S. flexneri ATCC 12022, E. gergoviae ATCC 33426, and M. smegmatis ATCC 14468 were assessed in vitro by the broth dilution method for determination of minimum inhibitory concentration (MIC). In addition, their inhibitory effects over DNA gyrase enzyme were evaluated using a DNA gyrase supercoiling assay. All the synthesized compounds showed a MIC value of either 8 or 16 μg/mL for M. smegmatis, whereas minimum to moderate activity was achieved for the others. Those tested in the supercoiling assay had at best a very mild inhibition of the enzyme. This series deserves further attention for testing over Mycobacterium species and topoisomerase II inhibition to develop new lead drugs to treat non-tuberculous mycobacterial infections.

Nitric oxide,anti-cancer agent,arylchloroethylureas - Abstract
New series of [(2-chloroethyl)ureido] benzoic acids (compounds 3-8) and nitric oxide releasing derivatives of [(2-chloroethyl)ureido] benzoic acid esters (compounds 9-14) were synthesized as potential anti-cancer agents. These compounds were screened for their anti-proliferative activities on A549 (human lung carcinoma) cells and for their cytotoxic effects on L929 (mouse fibroblast) cells. The compounds 3-8 exhibited mild cytotoxic effects on L929 cells (cell viability from 100% to 85% -- 90% only) whereas they had very little anti-proliferative activities towards A549 lung carcinoma cells. On the other hand, compounds 10, 11, and 13 had some growth inhibition activity in A549 (human lung carcinoma) cells. Among them, compounds 11 and 13 exhibited better anti-proliferative activities towards A549 cells, but also appeared to be cytotoxic towards L929 cells. In this group, the compound 10 with (1-(2-nitrooxyethyl)-3-[(2-chloroethyl)ureido]benzoate) structure appeared to have very weak anti-neoplastic activity towards A549 cells, with very little cytotoxic activity towards fibroblasts at physiological concentrations. Therefore, this compound is a better candidate for a potential anti-cancer therapy for non-small cell lung carcinomas. However, further studies are required in order to show applicability and effectiveness in animal models for this type of cancer.

Antimycobacterial activity,DNA gyrase activity,hydroxy-4H-pyran-4-one,homology modeling - Abstract
The World Health Organization lists tuberculosis among the top 3 leading causes of death from a single infectious agent, and reported cases of multidrug-resistant tuberculosis (MDR-TB) are on the rise. In an attempt to improve MDR-TB drug-directed therapy, we synthesized 11 4-substituted piperazine derivatives of 3-hydroxy-6-methyl-4H-pyran-4-one pharmacophore by reacting 5-hydroxy-2-methyl-4H-pyran-4-one with suitable piperazine derivatives under Mannich reaction conditions. Inhibitory effects of the 11 compounds on Escherichia coli DNA gyrase were evaluated via DNA gyrase supercoiling assay. The minimum inhibitory concentrations (MIC) of the 11 compounds and 41 compounds from our previous studies against Mycobacterium tuberculosis H37RV were assessed, in vitro, by a broth dilution method. To determine the interaction pattern between active site amino acids and all 52 compounds, homology modeling for the construction of M. tuberculosis DNA gyrase B subunit was performed, followed by a docking study. The data presented here could prove useful in future studies on interaction field analysis and high throughput virtual screening of the derivatives of the 3-hydroxy-6-methyl-4H-pyran-4-one pharmacophore toward the development of more clinically applicable compounds.

NITROGLYCERIN , *OINTMENTS , *DRUGSTORES , *DISPENSATORIES , *DRUG utilization , *LABELS - Abstract
Compounded drugs in pharmacies constitute negligible rate in the whole drug utilization. However, compounded drugs sometimes do not meet required standards and unfortunately their pharmaceutical specifications are not regularly controlled. In the present study, the amount of nitroglycerin active ingredient was measured in 23 nitroglycerin (0.4%) ointment samples prepared in 23 community pharmacies. In addition to the ingredient, the packaging and labeling were also evaluated. Our findings showed that 0.4% nitroglycerin ointment was prepared in only 4% of the pharmacies admitted. None of the compounded drugs met the acceptable (0.36-0.44%) range for 0.4% nitroglycerin content. Furthermore, nine of them were below the measurable value (<0.008%). The highest concentration of the compounded drugs was found 0.24%. Only three samples met the required active ingredient amount in terms of nitroglycerin and all of them were the pharmaceutical preparations of Rectogesic® with different serial numbers. Moreover, preparations compounded in the pharmacies lacked a proper packaging and labeling. We may conclude that there is a difficulty in accessing the above mentioned medication since the ointment was available in only 4% of the pharmacies and none of the preparations contained enough active ingredient. Only a few had proper package and adequate labeling. It seems that a regular auditing needs to be conducted for compounded drugs in the pharmacies [ABSTRACT FROM AUTHOR]

However, there was a strong correlation between Racotumomab doses and overall survival (OS). Mean OS of the patient with more than 10 Racotumomab application was significantly longer than the patient who had less than 10 injections (70.7 months vs. 31.1 months, p, NA

HASTANIN ECZACIYA BAKIŞIEczacılığın tarihçesi aslında insanlık tarihi ile aynıdır. Eczacı-hasta arasındaki bağ karşılıklı güven duygusuna bağlı olarak halk eczacıyı kendisine en yakın ve kolay ulaşılabilir danışman olarak görmektedir. Hastalığın tedavi sürecine katkı sağlayabileceği gibi, bireylerin moral ve motivasyon düzeyine ve tedavinin ekonomik düzenlenmesini sağlama konusunda da halk birçok açıdan eczane ve eczacılara danışmaktadır. Hastanın Eczacıya Bakışının incelenmesini amaçlayan bu çalışma anketlerle veri toplanması üzerine tasarlanmış gözlemsel-kesitsel bir araştırmadır. Hasta ve hasta yakınlarına 10 soruluk bir anket hasta ve hasta yakınlarına uygulanmıştır. Çalışma İstanbul'da bulunan serbest eczanede yapılmıştır. Hasta veya hasta yakını olup ankete katılmayı kabul ederek hazırda bulunan anket kağıdını okuma suretiyle işaretleyip imzalamak tek çalışmaya alma kriteri olarak kabul edilmiştir. Anket sorularının seçenekleri ki-kare (X2) fark analizi ile değerlendirilmiştir ve cinsiyet hariç bütün anket sorularının kendi içerisinden birbirinden farklı olduğu saptanmıştır. Anlamlı korelasyonların olduğu görülmüştür ve halkın eczaneleri bir sağlık sorunları olduğunda danışmak için gördüğü saptanmıştır. Katılımcıların yarıdan fazlasının (%53) her hafta (haftada 1 kere) eczaneye uğradığı görülmektedir. Eczaneye grip ve soğuk algınlığı için uğrama oranın %64 olduğu görülmektedir. Eczaneye uğrama gerekçesi değerlendirildiğinde bütün katılımcıların (%100) reçeteli ilaç almaya; %32'si eczaneye danışmaya geldikleri anlaşılmıştır. Ayrıca eczaneye uğrama bağımlı değişkeni regresyon analizi modeli oluşturulmuş bu regresyon modelin genel tahmin etme oranı %85 olarak saptanmıştır. Regresyon modeli için özgüllük %94,2; duyarlılık %64,5 olarak saptanmıştır. Regresyon modeli ile eczaneye uğrama durumu %59 açıklanabilmektedir. Katılımcıların nerdeyse tamamının (%97) eczacıların danışmanlığını yeterli görürken; %87'sinin eczacının reçeteye müdahalesini kabul ettiği saptanmıştır. Sonuç olarak Hastanın Eczacıya Bakışı çalışması eczacıların hem danışmanlık hem de reçete kontrolünde sık sık danışılan kişiler olduğunu ve halkın bazı hastalıklarda da doktorlardan önce eczaneye gittiğini göstermektedir.Anahtar Sözcükler: eczane, eczacınıza danışın, eczane teknisyeni, ilaç danışmanlığı PUBLIC VIEW OF THE PHARMACISTThe history of pharmacy is as similar as mankind history. Public feels the pharmacist the nearest and reachable advisor because of the pharmacist – patient relationship which depends on the mutual trust. Public ask pharmacists and community pharmacies for advice about treatment period of disease, motivation of individuals, financial design of the treatment. This study was designed by collecting data about public view of the pharmacist with questionnaires as observational, cross-sectional research. A questionnaire of 10 questions was applied on patients and patients' relatives to evaluate public view of the pharmacists. The study was made in a pharmacy in Istanbul. The only inclusion criteria of this study were reading, marking and signing the questionnaire by the patient or patient relative who were in the pharmacy. The questionnaire question options were analyzed with chi- square difference analysis (X2) and it was found that all the options were different in each group except gender. Significant correlations were found by correlation analysis and it was concluded that public consider pharmacies as an advisory when they have health problems. It was found that more than half of the participants (53%) visits pharmacy every week (once a week). Visiting pharmacy because of common cold was 64%. The reason to visit pharmacy was 100% buying prescribed drugs and 32% asking for advice. Regression analysis model of dependent variable of visiting pharmacy was made, and the general prediction rate of this model was found as 85%. The specificity of this regression model was 94.2%, sensitivity was 64.5%. Visiting pharmacy could be explained as 59% by regression model. While almost all of the participants (97%) consider pharmacist advisory is enough, 87% of them reported to accept pharmacist to interfere with the prescription. As a result, the public view of the pharmacist study shows that pharmacists are being referred both for advisory and supervision of prescription and public prefer to visit pharmacy before physicians for some diseases.

Kanser tüm Dünyada hızla yayılan, ölüm riski yüksek ve ülkemizde dolaşım sistemi hastalıklarından sonra en fazla ölüme sebep olan ikinci hastalıktır. Kanser tedavisinde cerrahi, radyoterapi ve/veya kemoterapi kullanılmaktadır. Cerrahi ve radyoterapi daha lokal bir alana uygulanabiliyorken kemoterapi sistemik etki sağlamaktadır. Kemoterapi tedavisinde kullanılan ilaçlar yüksek maliyetli ilaçlar olduğu için sağlığa ayrılan bütçede önemli bir yer tutmaktadır. Çalışmamız kemoterapide kullanılan ilaçlarda yarım doz imha maliyetlerini, maliyet tasarrufu sağlayarak kemoterapi ilaçlarına ayrılan gideri azaltmayı ve maksimum düzeyde ilaç, hasta ve çalışan güvenliğini hedeflemektedir. Çalışmamızda üç eğitim araştırma hastanesinin ilaçları ortak kemoterapi ilaç hazırlama cihazlarında hazırlanmaktadır. Hastane otomasyon programları üzerinden fatura edilen ilaç miktarları ve yarım doz ilaç imha miktarları raporlanmıştır. Excelde raporlar pivot tabloyla birleştirilerek analiz yapılmıştır. Hastanelerden ilaç hazırlama ünitesine görevlendirilen eczacılar, sorumlu eczacılar, hekimler ve hastane yönetimleriyle birlikte ortak çalışmalar ve takipler yapılmıştır. Hafta içerisinde patolojiye göre kemoterapi seanslarının rasyonel dağılımı, makul doz yuvarlaması yapılmış ve en önemli unsur da bir hastanede kalan yarım doz ilacın diğer hastane için kullanımı sağlanmış ve ilaç imhalarının önüne geçilerek gider azaltılmıştır. 18 aylık süreci kapsayan çalışmamızda imha maliyetlerinde yaklaşık 255.979,20 ₺ tutarında gider azalması gerçekleşmiştir. Çalışma yapılan merkezde ilaç hazırlama hizmetinin onkoloji alanında profesyonel, donanımlı eczacılar tarafından takibinin ve organizasyonun yapılmış olmasının, ilaç, hasta güvenliği ve düşük maliyet açısından olumlu sonuçlar verdiği görülmüştür. İstanbul, Ankara, İzmir gibi büyükşehirlerde büyük kompleks onkoloji merkezleri kurulmasının mevcut uygulamada olan ssitemlerden daha etkin olacağı düşünülmektedir.Anahtar Kelime: Kemoterapi, Antineoplastik, İmha, Maliyet Cancer incidence, rising rapidly in the World, carries a high mortality rate and causes the most deaths after cardiovascular diseases in our country. Surgery, radiotherapy and chemotherapy are different ways in which cancer is treated. While surgery and radiotherapy can be used in treatment of a local area, chemotherapy yields a systemic effect. Drugs used in chemotherapy treatment occupy an important place in the budget allocated to health, given their high costs. This study aims that reduce the half dose costs, reducing the chemotherapy drugs expense by the cost saving and drug, patient and employee safety in maximum level. In our work, drugs of three educational research hospitals are prepared in shared chemotherapy drug preparation devices. Drug amounts, invoiced through hospital automation programs, and the disposal cost of half dose drugs were reported. These reports were then consolidated into pivot tables in Excel and analyzed. Together with pharmacists assigned to drug preparation units by hospitals, authorized pharmacists, physicians and hospital managers studies and follow-up analyses were undertaken. Chemotherapy sessions on weekdays based on pathology reports were rationally distributed, reasonable dose rounding was conducted and most notably, half dose drugs left unused in hospitals were put to use in others, whereby drug disposals were prevented and costs were reduced. Throughout this work spanning across 18 months a cost reduction of approximately 255.979,20 TL was generated in the amount of disposal costs. This work observed that, at the center where this study was conducted, having well-equipped pharmacists specialized in the field of oncology serve in and watch drug preparation services yields positive results both in drug and patient safety as well as in reducing costs. It is suggested that establishing large-scale, complex oncology centers in major cities like Istanbul, Ankara, Izmir will prove to be more effective than existing systems.Anahtar Kelime: Kemoterapi, Antineoplastik, İmha, Maliyet 85

Diyabetli hastalar genel popülasyona göre daha fazla enfeksiyona eğilimlidirler ve bunlar arasında üriner enfeksiyonlara (ÜE) daha sık rastlanmaktadır. Bu çalışmada diyabet tanılı hastalardaki ÜE; kan ve idrar tahlillerinin parametreleri, hastaların demografik özellikleri, hastaların kullandığı ilaçlar bütüncül bir değerlendirmeye tabi tutulmuştur. 2015 yılının muhtelif aylarında İstanbul'da bulunan bir hastanenin uzman hekim/lerinin ÜE tanısını koyduğu ve idrar tahlili ile eczane ve/veya hastane elektronik sağlık verilerinden ÜE ve eşlik eden hastalıkları tespit edilen hasta verileri SPSS istatistik programı ile analiz edilmiştir. Tamamı diyabetik olan örneklemde ÜE görülme oranı %22 (Kadın: %32; Erkek: %3), örneklemin cinsiyete göre ÜE açısından farklı olduğu saptanmıştır. Hipertansiyonun, dislipidemi, miyalji, ASYE, Göğüs ve GİS hastalıkları, görülme sıklığı ÜE grupları arasında birbirinden farklı olmadığı saptanmıştır. ÜE gruplarının TSH, VitB12, serbest tiroksin, trigliserit, HBA1C, AKŞ, CRP, WBC açılarından birbirinden farklı olmadığı görülmüştür. ÜE olanlarda idrar lökosit ortalaması 4,4 iken olmayanlarda idrarda bulunan lökosit ortalama değeri 1,8 olarak saptanmıştır. ÜE grupların idrar lökositi ve idrar eritrositi açılarından birbirinden farklı oldukları saptanmıştır. ÜE görülenlerde insülin kullanma oranı %64 iken; ÜE görülmeyenlerde bu oranı %24 olarak saptanmıştır. ÜE görülenlerde OAD ve insülinin beraber kullanılma oranı %55 iken; ÜE görülmeyenler arasında sadece OAD ve insülinin beraber kullanma oranı %15 olarak saptanmıştır. İnsülin kullananlardaki ÜE görülme riski insülin kullanmayanların 3,6 katıdır (RR=3,6; p=0,001). OAD ve/veya insülin kullananlar arasında HBA1C ve CRP açısından grupların birbirinden farklı olduğu saptanmıştır. Enfeksiyon ilacı kullanımı cinsiyete göre anlamlı derecede farklılık göstermektedir. Siprofloksasin kullanımı kadınlarda %29 erkeklerde %3 olarak saptanmıştır. Çalışma diyabetik ÜE hastalarının ilaç kullanımı ve multimorbidite yönetiminde literatürle uyuşmayan yönlerinin olduğunu ortaya koymuştur. Klinik eczacının bu karmaşık ilaç kullanımını yeniden değerlendirmeye tabi tutmasının hastanın yararına olacağı düşünülmektedir.Anahtar Sözcükler: diyabet, multimorbidite, üriner enfeksiyon, polifarmasi The patients with diabetes are more vulnerable to infections compared with normal population and urinary tract infection (UTI) is more common infection type. In this study UTI, blood, urine sample parameters, the demographic data and medications of patients are analyzed holistically. The data of patients that were diagnosed as UTI by physician/s in nonspecific months of 2015 in İstanbul, which is urine sample that was provided by digital health data of hospital or pharmacy of patients was analyzed by SPSS statistic program. In the sample which all of it is diabetic, the UTI frequency was found 22% (32% female, 3% male), the sample differs in between UTI according to gender. There was no difference between UTI groups in frequency of hypertension, dyslipidemia, myalgia, lower respiratory tract infection, pulmonary and gastrointestinal diseases. There was no difference between UTI groups in TSH, VitB12, free T4, triglyceride, HBA1C, fast blood glucose, CRP, WBC results. The urine WBC was found 4.4 in UTI positive patients, and it was 1.8 that were UTI negative. It was found that urine WBC and RBC was different between groups. Insulin prescription rate was 64% in UTI positive group and it was 24% in UTI negative group. The OAD and insulin together prescription rate was 55% in UTI positive group, and it was only 15% in UTI negative group. The risk of UTI in insulin prescribed patients is 3.6 times more than non-insulin prescribed patients (RR=3.6; p=0,001). HBA1C and CRP levels were different between groups among OAD and/or insulin prescribed patients. The prescription of infection medications was significantly different among genders. Ciprofloxacin prescription frequency was 29% in female, and 3% in males. This study found that diabetic UTI patients differs from literature in medication and multimorbidity management. It is thought that it will be for benefit of patient to be evaluated by clinical pharmacist the complex medical drug prescription.Key Words: diabetes, multimorbidity, urinary tract infection, polypharmacy 118

Günümüzde akne vulgaris tanısı alan hastalar arasında isotretinoin kullanımı gittikçe artış göstermektedir. Bu çalışmaya isotretinoin tedavisi alan akne vulgaris tanılı eczaneye ilaçlarını temin etmeye gelmiş hastalar arasından seçilen 194 hasta dahil edilmiştir. Bu çalışma ile isotretinoin tedavisi alan hastaların klinik eczacı tarafından eğitimi ve hasta takibi ile hastaların tedavilerinin doğru planlanması amaçlanmıştır. Oral isotretinoin tedavisi gören 194 hastanın 52'sinde ilaç etkileşimi ve 2'sinde kontrendike durum tespit edilmiş ve eczacı tarafından hastaların doktorları ile birlikte gerekli düzenlemeler yapılmıştır. Bu gibi istenmeyen durumların, ilaç etkileşimleri ve ilacın doğru kullanımı gibi bilgilerin klinik eczacı tarafından farkedilerek hasta eğitiminin sağlanmasının ve doktoru bilgilendirmesinin hastanın tedavi uyuncuna etkisinin büyük olduğu görüldü. Yine hasta eğitimi kapsamında tedavinin belirli bir süreç olması sebebiyle hastaların bu süreci eczacıların danışmanlığıyla en uyumlu şekilde geçirebileceği bilgileri verildi. Eczacılarından yeterli bilgi ve eğitim alan, tedavi süresince eczacılarına danışan hastaların tedavi başarı oranında artış görülerek klinik eczacıların isotretinoin tedavisi alan hastalarda önemli bir rolü olduğu görülmüştür. Çalışma sonunda tedavide hastanın öncelikle doktoru sonrasında eczacı tarafından eğitiminin yapılmasının tedavinin doğru yapılması ve hastanın uyuncunun sağlanmasında büyük öneme sahip olduğu görülmüştür. Hasta eğitimi ve takibinde multidisipliner ekibin içerisinde klinik eczacının bulunmasının etkili ve değerli olduğu anlaşılmıştır. Today, isotretinoin use is increasing among patients diagnosed with acne vulgaris. This study included 194 patients selected from patients who came to the pharmacy with the diagnosis of acne vulgaris on isotretinoin treatment. The aim of this study was to educate the patients who received isotretinoin treatment by clinical pharmacist and to plan the treatment of the patients with patient follow-up. Of the 194 patients receiving oral isotretinoin, 52 had drug interactions and 2 had contraindicated conditions, and the pharmacist made the necessary arrangements with the doctors of the patients. It was observed that such adverse events, drug interactions and correct use of the drug were recognized by the clinical pharmacist, and the provision of patient education and informing the doctor had a significant effect on the compliance of the patient. In the context of patient education, because the treatment was a specific process, the patients were informed that they could pass this process in the most compatible way with the pharmacist's counseling. The success rate of the patients who received adequate information and training from pharmacists and who consulted the pharmacists during the treatment was increased and clinical pharmacists played an important role in patients receiving isotretinoin treatment. At the end of the study, it was found that the training of the patient first by the doctor and then by the pharmacist makes great importance in ensuring the correct treatment and ensuring the compliance of the patient. It was understood that the presence of a clinical pharmacist in the multidisciplinary team was effective and valuable in patient education and follow-up.

Diyabet, insülin sekresyonu ve/ veya etki mekanizmasındaki bozukluklar sonucu ortaya çıkan, hiperglisemi ile karakterli, enfeksiyon dışı epidemilere sebep olan endokrin hastalıklar içinde önemli bir yere sahip metabolik bir hastalık grubudur. Bu hastalık dünya genelinde gitgide artan prevelansıyla gözlenmesi gereken ve hayat boyu tedavisi imkânsız olan metabolik bir hastalıktır. Uluslararası Diyabet Federasyonu (IDF) küresel diyabet prevalansının hızlı ve tehlikeli bir şekilde artış gösterdiğini belirtmiştir. Araştırmalara göre 2012 yılında 371 milyon kişinin bu hastalığa maruz kaldığı gözlenmiştir. Bu araştırmada diyabetik hastalarda klinik eczacının ve verdiği bilgi ve eğitimlerin etkisinin tespit edilmesi hedeflenmiştir. Bu amaç doğrultusunda diyabetli hastalarda HbA1c düzeyi, klinik eczacı tarafından verilen eğitimi almadan önce ve sonrasındaki farklılık analiz edilmiştir. Çalışmamıza yaşları 38-75 arasında olan, 29'u erkek (%58), 21i kadın (42) olmak üzere toplam 50 diyabetli hasta dahil edilmiştir. Yapılan çalışmada elde edilen verilerin analizi neticesinde klinik eczacı tarafından eğitim alan hastların HbA1c düzeyi daha düşük çıktığı görülmüştür. Araştırmamıza katılan hastaların tedavi öncesi HbA1c değerleri ortalaması 7,21±1,37 (5,1-11,7)'dir. Bilgilendirme sonrası 3. ay HbA1c değerleri ortalaması 7,01±1,07 (5,0-8,9) bulunmuştur. Diyabetin kısa ve uzun dönemde insanlarda oluşturduğu tüm olumsuzluklar eğitim ve takip ile giderilebilir. Hastaya verilen eğitim ile bilincin artması bu olumsuzlukları giderecek ve devletin de üstüne binen sağlık masraflarından kurtaracaktır.Anahtar kelimeler: Diabet, Diabet Eğitimi, Klinik Eczacı. Diabetes is a group of metabolic endocrine diseases that occur due to insulin secretion and / or impaired mechanism of its action, characterized by hyperglycemia and and cause non-infectious epidemics. This disease is observed worldwide with its increasing prevalence and it is a life-long treatment. The International Diabetes Federation stated that the prevalence of global diabetes has increased rapidly and dangerously. In 2012, 371 million people suffered from this disease. The aim of this study was to determine the role of clinical pharmacists and the education they provide in diabetic patients. In this study, HbA1c level in patients with diabetes was analyzed before and after the education given by the clinical pharmacist. A total of 50 diabetic patients were included in the study, aged between 38-75 years, 29 male (58%) and 21 female (42). As a result of the analysis of the data obtained from the study, it was seen that HbA1c level of the patients trained by the clinical pharmacist was lower. The mean HbA1c values of the patients participating in our study before treatment were 7.21 ± 1.37 (5.1-11.7). The mean HbA1c values at the third month after the information was 7.01 ± 1.07 (5.0-8.9). All shortcomings of diabetes in the short and long term can be solved by training and follow-up. Raising awareness with the education given to the patient will eliminate these negativities and save the health expenses incurred by the state.Keywords: Diabetes, Diabetes Education, Clinical Pharmacist. 52

Birçok ülkede yaşlıların uygunsuz ilaç kullanımlarını azaltmak üzere bazı kriterler konsensüs şeklinde belirlenmektedir. Beers 2019 Kriterleri esas alınarak yaptığımız bu çalışma ile birinci basamak sağlık merkezi olarak kabul edilen serbest eczanelerde karşılanan geriatrik reçetelerin dağılımı ve kriterlere uygunluğu raporlanmıştır. Çalışma İstanbul merkezli retrospektif kesitsel bir çalışmadır. Ocak 2014 -Şubat 2019 arasında İstanbul Şişli'deki bir eczanede karşılanan 13906 ayrı hastanın, toplam 66136 reçetesine ait elektronik kayıtlar analiz edilmiştir. Her ilaç grubu için bir ortalama yaş hesaplanmış olup bütün olgularda ortalama yaş 16,8-68,1 yıl arasında değişirken; geriatrik olgular için 73,4-76,1 yıl olarak saptanmıştır. Çalışmamızın 66136 (21980 geriatrik) reçete sayısı ile 13906 (2856 geriatrik) farklı hastada yapılmıştır. Başka bir ifade ile bu süre boyunca bir hasta yaklaşık 5 defa (4,76) eczaneye uğramıştır. Reçetelerin %33,2'si geriatrik iken; hasta bazında bu oranın %20,5 olduğu saptanmıştır. Reçete bazında geriatrik oranın daha yüksek olması geriatrik hastaların daha fazla reçete alması ile açıklanabilir. Altmış bir aylık sürede karşılanan 66136 reçetenin 40187'si kadın (%61) reçetesi; 25949'u (%39) erkek reçetesi olup kadınların %33,1'i geriatrik iken erkeklerin %33,4'ü geriatrik olarak saptanmıştır. Hasta sayısı olarak bakıldığında 13906 hastanın 8282'inin (%59,6) kadın olduğu ve bu kadınların 1729'unun (%21) geriatrik olduğu saptanmıştır. Geri kalan 5624 erkek hastanın 1127'sinin (%20,0) geriatrik olduğu saptanmıştır. Çalışmamız ayrıntılı olarak reçete bazında incelendiğinde Nifedipin (n=410) %68,8; Amiodaron (n=43) %44,2; MSS ilaçları (n=506) %21,5; Barbiturat (n=67) %0; Glimepiride (n=177) %53,7; PPİ (n=2052) %29,2 olarak Beers kriterlerine uygunsuzluk saptanmıştır. Dünya genelinde, Beers ve benzerleri ile tespit edilen uygunsuzluk prevelansı %13-35 dolaylarında iken Avrupa için bu oran ortalama %23 iken ülkemizde %33 civarındadır. Bu çalışmanın ülkemiz özelinde yaşlılar ile ilgili yapılacak Beers kriteri benzeri bir çalışmanın ilk adımları olabileceği düşünülmektedir. In many countries to decrease inappropriate medicine use of elderly people some criteria are identified in consensus. By the help of this study that we arranged based on Beers 2019 criteria, the geriatric prescription variance which are processed in community pharmacies that are primary health care centers and fitting the criteria has been reported. The research is retrospective, cross-sectional Istanbul centered study. Electronic records of 66136 prescriptions that belong to 13906 different patients which were processed between January 2014- February 2019 in a pharmacy in İstanbul Şişli was analyzed. For each medicine group a mean age has been calculated. The age means of these medicine groups varies between 16.8 – 68.1 for the whole sample. The age means varies between 73.4- 76.1 for geriatric patient group. 66136 (21980 of that was geriatric) prescriptions and 13906 (2856 of that was geriatric) different patients were analyzed in this study. In a different saying a patient has visited the pharmacy almost 5 times (4.76) during this period. 33.2 % of prescriptions were geriatric, while 20.5 % of patients were geriatric. The percentage of geriatric prescription is higher which is explained by geriatric patients getting more prescriptions than the other age group patients. 40187 of 66136 prescription was female prescription (61%), 25949 was male prescription (39%) which were studied during the research period that is 61 months. 33.1% of female patients were geriatric, 33.4% of male patients were geriatric. Of 13906 patients 8282 (59.6%) were female and 1729 (21%) of them were geriatric. 5624 of the patients were male and 1127 (20%) of them were geriatric. When the prescriptions analyzed in detail; it was found inappropriate prescribing according to Beers criteria in the following medicines respectively; nifedipine (n=410) 68.8 %, amiodarone (n=43) 44.2%, CNS medicine (n=506) 21.5%, barbiturate (n=67) 0%, glimepiride (n=177) 53.7%, PPI (n= 2052) 29.2%. While the inappropriateness prevalence, which is determined by Beers and similar criteria, is between 13-35% all around the world, it is 23% in European countries and 33% in our country. It is thought that this study may be the first step of a study similar to the Beers criterion related to the elderly in our country. 103

Ülkemizde dünyadakinin aksine yeniden kullanım potansiyeli olan ilaçların ne yapılacağı hakkında bir düzenleme henüz yoktur. Kontrolsüz yürütülen ilaç toplama faaliyetlerinin düzenli bir şekilde yürütülmesi için literatür ve mevzuat eksikliğinin olması ve ilgili konuda literatüre katkı amacıyla bu anket çalışmasına ihtiyaç duyulmuştur.Katılımcı eczacıların yaş ortalamasının 36,1±9,8 olduğu; %63'ünün erkek %37'sinin kadın olduğu; %65'inin İstanbul'da %35'inin İstanbul dışında mesleğini icra ettiği;13±9,1 yıl mesleki tecrübeye sahip olduğu ve bunun cinsiyete göre birbirinden farklı olduğu saptanmıştır.Kullanılmayan ilaçların toplanmasını organize edecek olan bir organizasyona destek verenler hem maddi hem de bizatihi destek verme isteğindedir. Eczanelerde miadı dolduğu için imha edilen ilaçlar nedeniyle yıllık ortalama 3397 TL mali kaybın olduğu,eczanelerde aylık ortalama 17kutu (561 TL) ilaç unutulduğu; evlerinde kullanılmayan ilaç sayısı ortalama 10,1±7,76 kutu; kullanımı bırakılan 6,2±6,11 (198±315,6 TL)kutu;miadı dolan ortalama kutu sayısının 2,9±4,67 olduğu, eczacıların %70'inin miadı dolan ilaçları kullandığı tespit edilmiştir.Eczacıların %68'inin bağış/hibe ilaç kabul ettiğini belirtmişken; %83'üne en az bir kere ilaç bağışının yapıldığıancak %92'sinin ceza almaktan çekindiği anlaşılmıştır.Son bir senede eczacı/eczanelerin miadı dolduğu için imha ettiği ilaçların kutu sayısıgruplara göre sırasıyla şu şekilde olmuştur: Antihipertansif, Antibiyotik, Analjezik, Antidepresan-antipsikotik, Diyabet ilaçları ilk 4 grup olup bunlarınçalışmanın %62'sini oluşturduğu saptanmıştır.Şu anda eczanenizde mevcut olan ve hastaların iade/bağış/hibe etmiş olduğu ilk üç grup ilacın etken maddesi/maddeleri sorusuna cevap olarak da toplamda 131 (53 farklı) etken madde belirtilmiştir.Sonuç olarak çalışmamız ilaç israfının büyük boyutlarda olduğunu ve eczacıların bu israfı azaltmak için maddi ve manevi destek vermeye hazır olduğunu göstermiştir. Kullanılmayan ilaçların tekrar ekonomiye kazandırılması organizasyonlarından uzak kalan eczacıların buna sebep olarak en fazla yürürlükteki mevzuatlardan şikayetçi oldukları görülmüştür.Anahtar Sözcükler:farmako-ekonomi,ilaçbağışı, eczanelerdeki ilaç israfı There is not any policy about what to do with the medicines that have the potential to be reused, opposite to the World. This survey was needed because of lacking literature which will decrease the waste of medicine for the process of gathering the medicines by the people who are not professional. It was found that the mean age of the pharmacist that took place in the survey was 36,1±9,8; 63% of them was male, while 37% was female; 65% of them were working İstanbul, while 35% were working out of İstanbul; mean years of working was 13±9,1 and this was different between genders. In other words, the pharmacists that give the medicines to an organization to gather the medicines support this process both financially and personally. The pharmacists have mean money waste per year 3397 TL and 17 (561 TL) boxes of medicines is forgotten in pharmacies per month. The mean boxes of the medicines that are not used at home is 10,1±7,76, the given up medicine at home is 6,2±6,1 the mean of the medicine boxes that have the expiration date were 2,9±4,67. 70% of the pharmacists use the medicines that reached the expiration date. 68% of the pharmacists accept charity medicine and 83% of them had at least once a charity medicine but 92% of them were afraid of being charged by healthauthorities. Because of reaching the expiration date, the extirpated medicine box number during the last year was respectively; antihypertensives, antibiotics, analgesics, antidepressants- antipsychotic, diabetes mellitus were the first 4 groups and formed 62 % of the study. The answer of the mostly taken 3 groups of medicine as charity in the pharmacies were 131 active ingredients and 53 of them were different. As a conclusion our research found that medicine waste is too much and the pharmacists are ready to decrease this waste both financially and personally. The reason for pharmacists not to take place in organizations that design the reuse of the medicines is mostly the laws.Key Words: pharmaco-economy, charity medicine, drug waste in pharmacies 108

Amaç: Non-steroidal antienflamatuvar ilaçlar (NSAİİ), dünya genelinde en sık reçete edilen, ağrı ve enflamasyon için oldukça etkili ilaç gruplarından biridir. Ancak gastrointestinal yan etkileri sebebiyle hastalar kronik tedavileri tolere edememektedir. Bu çalışmada daha önce sentezlenmiş olan imidazolil-tiyoasetil-pirazolinon türevi 12 maddenin siklooksigenaz (COX) enzim inhibisyonu, enflamasyon ve mide mukozası üzerine etkileri incelenmiştir.Gereç ve Yöntem: COX-1 ve COX-2 enzim inhibisyonu floresan görüntüleme kiti yardımıyla in vitro olarak çalışılmış, COX-2 inhibiyonu yüksek olan 4 madde seçilerek in vivo antienflamatuvar aktiviteleri incelenmiştir. Bu amaçla, 8-12 haftalık erkek, BALB/c fareler kontrol (DMSO), referans grupları (indometazin, naproksen) ve 4 deney grubu (2b,2c,2d,2e) olmak üzere 7 gruba (n=7) ayrılmıştır. İn vivo olarak tüm hayvanlarda karagenan ile indüklenmiş pençe ödemi oluşturulmuş ve gavaj yoluyla kontrol, referans ve deney maddeleri uygulanmıştır. Saat başı pençe kalınlığı ölçülmüştür ve sonuçlar kontrol ve referans grupları ile karşılaştırılmıştır. 7 saat sonunda fareler sakrifiye edilerek mideleri alınmış ve mide mukozasında peteşiler gözlenmiştir.Bulgular: İn vitro enzimatik aktivite analizi sonucu maddelerin COX enzimlerini inhibe ettiği gözlenmiş, COX-2 inhibisyonu yüksek olan 4 madde ile in vivo çalışma yapılmıştır. Referans ve test edilen 4 maddenin kontrol DMSO grubuna kıyasla pençe ödemini anlamlı derece azalttığı gözlenmiştir. 2b ve 2c maddeleri indometazine benzer etkinlik göstermiştir. Mide ülserasyon sonuçlarında ise referans gruplarda görülen mukoza hasarı imidazolil-tiyoasetil-pirazolinon türevi 4 grup için gözlenmemiştir.Sonuç: İmidazolil-tiyoasetil-pirazolinon türevi moleküller günümüzde kullanılan NSAİ ilaçlar benzeri antienflamatuvar aktivite göstermesi ve gastrointestinal yan etki oluşturmaması sebebiyle COX-2 selektif yeni ilaç olmaya adaydır. Anahtar Kelimeler: enflamasyon, NSAİİ, siklooksigenaz, ülserasyon, analjezik Aim: Non-steroidal anti-inflammatory drugs (NSAIDs) are one of the most commonly prescribed medication groups for pain and inflammation worldwide. However, patients cannot tolerate chronic treatments due to gastrointestinal side effects. This study aims to investigate the effects of synthesized imidazolyl-thioacetyl-pyrazolinone derivatives on cyclooxygenase (COX) enzyme inhibition, inflammation and gastric mucosaMaterial and metods: Inhibition of COX-1 and COX-2 enzymes were studied by using the fluorescent screening. In vivo anti-inflammatory activities were investigated by selecting 4 compounds with high COX-2 inhibition. 8-12 weeks old male, BALB/c mice were divided into 7 groups (n=7) including control (DMSO), reference groups (indomethacin, naproxen) and 4 experimental groups (2b,2c,2d,2e). Carrageenan-induced paw edema was induced in all animals and control, reference and experiment compounds were administered by gavage. The paw thickness was measured and the results were compared to the control and reference groups. After 7 hours, the mice were sacrificed, stomachs were removed and gastric petechias were observed. Results: In vitro enzymatic activity analysis showed that molecules inhibit COX enzymes and in vivo studies were conducted with 4 substances with high COX-2 inhibition. It was observed that the 4 tested molecules significantly reduced paw edema compared to the control DMSO group. Items 2b and 2c showed similar activity to indomethacin. In gastric ulceration results, mucosal damage in reference groups was not observed for imidazolyl-thioacetyl-pyrazolinone derivative 4 groups. Conclusion: Imydazolyl-thioacethyl-pyrazolinone-derived molecules are potential candidates for COX-2 selective NSAIDS, regarding anti-inflammatory effects as well as these do not show any gastrointestinal side effects as current NSAIDs.
