Nanotechnology plays a pivotal role in the biomedical field, especially in the synthesis and regulation of drug particle size. Reducing drug particles to the micron or nanometer scale can enhance bioavailability. Supercritical fluid technology, as a green drug development strategy, is expected to resolve the challenges of thermal degradation, uneven particle size, and organic solvent residue faced by traditional methods such as milling and crystallization. This paper provides an insight into the application of super-stable homogeneous intermix formulating technology (SHIFT) and super-table pure-nanomedicine formulation technology (SPFT) developed based on supercritical fluids for drug dispersion and micronization. These technologies significantly enhance the solubility and permeability of hydrophobic drugs by controlling the particle size and morphology, and the modified drugs show excellent therapeutic efficacy in the treatment of hepatocellular carcinoma, pathological scarring, and corneal neovascularization, and their performance and efficacy are highlighted when administered through multiple routes of administration. Overall, supercritical fluids have opened a green and efficient pathway for clinical drug development, which is expected to reduce side effects and enhance therapeutic efficacy.

Older people are often affected by impaired organ and bodily functions resulting in multimorbidity and polypharmacy, turning them into the main user group of many medicines. Very often, medicines have not specifically been developed for older people, causing practical medication problems for them like limited availability of easy to swallow formulations, easy to open packaging and dosing instructions for enteral administration. In 2020, the European Medicines Agency (EMA) published a reflection paper 'Pharmaceutical development of medicines for use in the older population', which discusses how the emerging needs of an ageing European population can be addressed by medicines regulation. The paper intends to help industry to better consider the needs of older people during pharmaceutical/clinical medicines development by summarising data on the most relevant topics, providing early suggestions on how to move forward and prompting expert discussions and studies into knowledge gaps. Topics include patient acceptability, (dis)advantages of an administration route, formulation, dosage form, packaging, dosing device and user instruction. While the paper is directed at older people and the pharmaceutical industry, the reflections are also relevant to younger patients with similar disease‐related needs and of value to other stakeholders parties, e.g., healthcare professionals, academics, patients and caregivers, as the paper makes clear what can be expected from industry and where collaborative work is needed. This commentary provides an overview of the different steps in the development of the reflection paper, discusses points considered most controversial and/or subject to (multidisciplinary) expert discussions and indicates their value for real world clinical practice.

This systematic review explored the multifaceted impact of drug price regulation on patient access to essential medicines. Recognizing the complexity of this relationship, the paper investigates the influence of various types of drug price regulation mechanisms, the disparities across different geographical regions and health-care systems, and the differential effects between branded and generic drugs. Our findings illustrate that the effects of drug price regulation are not universally uniform or predictable, but rather, they are highly context dependent. Direct price control measures can, on the one hand, improve accessibility through affordability; yet on the other hand, potentially disrupt drug supply. Indirect price control methods, such as reference pricing and value-based pricing, while designed to spur competition, can be hampered by administrative complexities and potentially stifle pharmaceutical innovation. Despite the pervasive use of drug price regulation, access to essential medicines remains disparate and inequitable, indicating a need for a comprehensive approach that includes health system reforms, improved health literacy, and greater collaboration between stakeholders. Future research should further investigate the enduring disparities in patient access to medicines, the long-term effects of various pricing mechanisms, and their interplay with the evolving pharmaceutical industry and health-care landscapes.

Pharmaceutical sector corruption undermines patient access to medicines by diverting public funds for private gain and exacerbating health inequities. This paper presents an analysis of UN Convention Against Corruption (UNCAC) compliance in seven countries and examines how full UNCAC adoption may reduce corruption risks within four key pharmaceutical decision-making points: product approval, formulary selection, procurement, and dispensing. Countries were selected based on their participation in the Medicines Transparency Alliance and the WHO Good Governance for Medicines Programme. Each country’s domestic anti-corruption laws and policies were catalogued and analysed to evaluate their implementation of select UNCAC Articles relevant to the pharmaceutical sector. Countries displayed high compliance with UNCAC provisions on procurement and the recognition of most public sector corruption offences. However, several countries do not penalise private sector bribery or provide statutory protection to whistleblowers or witnesses in corruption proceedings, suggesting that private sector pharmaceutical dispensing may be a decision-making point particularly vulnerable to corruption. Fully implementing the UNCAC is a meaningful first step that countries can take reduce pharmaceutical sector corruption. However, without broader commitment to cultures of transparency and institutional integrity, corruption legislation alone is likely insufficient to ensure long-term, sustainable pharmaceutical sector good governance.

Background: The US Food and Drug Administration (FDA) has expanded the use of surrogate markers in drugs approved for oncology/hematology indications. This has likely resulted in a greater number of approvals and possibly drugs coming to market faster, but it is unknown whether these drugs also improve overall survival (OS) for patients taking them. Methods: We sought to estimate the percentage of oncology drugs that have shown to improve OS in a cross‐sectional analysis of US FDA oncology drug approvals (2006–2023). We searched for OS data in registration trials and the peer‐reviewed literature. Results: We found 392 oncology drug approvals. Eighty‐seven (22%) drug approvals were based on OS, 147 drug approvals were later tested for OS benefit (38% of all approvals and 48% of drugs approved on a surrogate), and 130 (33%) have yet to be tested for OS benefit. Of the 147 drug approvals later tested for OS, 109 (28% of all approvals and 74% of drugs later tested for OS) have yet to show OS benefit, whereas 38 (10% of all approvals and 26% of drugs later tested for OS benefit) were later shown to have OS benefit. In total, 125 out of 392 (32%) drugs approved for any indication have been shown to improve OS benefit at some point, and 267 (68%) have yet to show approval. Conclusion: About 32% of all oncology drug approvals have evidence for an improvement in OS. Higher standards are needed in drug regulation to ensure that approved drugs are delivering better patient outcomes, specifically in regards to survival. [ABSTRACT FROM AUTHOR]

Innovative health technologies are not well regulated under current pathways, leading regulators to adopt contextual, life-cycle regulatory models, which authorize drugs based on earlier clinical evidence subject to the conduct of post-market trials that confirm clinical benefit and safety. In this paper, we evaluate all drugs authorized in Canada under the Notice of Compliance with conditions (NOC/c) policy from 1998 to 2021 to analyze its function, identify challenges and areas for improvement, and make recommendations to inform Health Canada's regulatory reforms. We analyzed a sample of 148 drugs authorized between 1998 and 2021, including characteristics about the pre- and post-market clinical trials, finding that most NOC/c authorizations are based on one, single-arm clinical trial using a surrogate endpoint. Post-market trials are more likely to be randomized, Phase III trials but mostly use surrogate endpoints. Based on our findings, we recommend increasing decision-making transparency throughout the regulatory process, developing comprehensive eligibility criteria for selecting appropriate health technologies, modernizing pre-market evidence requirements, adopting a more active role in designing post-market trials, and utilizing automatic expiry, stronger penalties, and ongoing disclosure of the status of post-market trials to promote compliance.

In several controversial drug approval decisions in recent years, the Food & Drug Administration ("FDA") has publicly justified its decision partly on the ground that approving the drugs in question would support innovation in those fields going forward. To some observers, these arguments were surprising, as the Agency's determination whether a drug is "safe" and "effective" does not seem to depend on whether its approval also supports innovation. But FDA'suse of these innovation arguments in drug approval decisions is just one example of the ways in which the Agency has come to make many innovation-related judgments as part of its regulation of drugs. In this Article, we investigate the broad set of innovation-related judgments that FDA has been making and argue that there are serious concerns with the major innovation role FDA has been playing, at least as the Agency is currently constituted. We conclude that FDA should not separately weigh innovation in decisions about a product's safety and effectiveness. In other areas, health policymakers could reasonably decide that FDA should have either a larger or a smaller role than it currently does in shaping the development of novel drugs. But policymakers should do so while thoughtfully considering both the opportunities and challenges of FDA actively considering innovation incentives in its decisions; those challenges have been rarely considered in the literature and policy discourse. Further, we argue that whether policymakers aim to bolster or limit the ways that FDA considers innovation in its regulatory decisions, changes are needed to the Agency's structure to support its ability to make reasoned judgments based on relevant expertise.

Background: Drug use is a major public health issue in India. Significant changes in the approach toward drug use have happened in the last few decades. Despite this, no systematic attempt has been made to document the same in the scientific literature. This narrative review attempts to discuss the major drug laws, policies, and national programs of the Government of India (GoI). Methods: A thorough search was conducted to look for policies, programs, acts, and notifications related to substance use/drug use on various websites of different ministries of the GoI. Acts, programs, and policies addressing substance use were identified. Results: Various drug laws, programs, and acts from the GoI provide a multipronged approach to curbing the procurement of drug use along with its prevention and cure. The Ministry of Social Justice and Empowerment (MoSJE) is the nodal ministry for drug demand reduction. The enactment of the Narcotic Drugs and Psychotropic Substances (NDPS) Act 1985 and Policy 2012 and the implementation of India's Drug De-Addiction Program (DDAP) are important landmarks in this journey. Conclusion: The GoI initiatives for reducing the mental health burden in this country in general and substance use disorders (SUDs), in particular, are immense. The acts/statutes/laws/notifications are all interlinked. Stakeholders in mental health, public health, and policy-making need to upgrade themselves with the relevant statutes to curb the menace of drug use. [ABSTRACT FROM AUTHOR]

Tuberculosis is a chronic and lethal infectious disease caused by Mycobacterium tuberculosis. In previous decades, most studies in this area focused on the pathogenesis and drug targets for disease treatments. However, the emergence of drug-resistant strains has increased the difficulty of clinical trials over time. Now, more post-translational modified proteins in Mycobacterium tuberculosis have been discovered. Evidence suggests that these proteins have the ability to influence tuberculosis drug resistance. Hence, this paper systematically summarizes updated research on the impacts of protein acylation and phosphorylation on the acquisition of drug resistance in Mycobacterium tuberculosis through acylation and phosphorylation protein regulating processes. This provides us with a better understanding of the mechanism of antituberculosis drugs and may contribute to a reduction the harm that tuberculosis brings to society, as well as aiding in the discovery of new drug targets and therapeutic regimen adjustments in the future.

The paper focuses on the development of a multifractal theoretical model for explaining drug release dynamics (drug release laws and drug release mechanisms of cellular and channel-type) through scale transitions in scale space correlated with experimental data. The mathematical model has been developed for a hydrogel system prepared from chitosan and an antimicrobial aldehyde via covalent imine bonds. The reversible nature of the imine linkage points for a progressive release of the antimicrobial aldehyde is controlled by the reaction equilibrium shifting to the reagents, which in turn is triggered by aldehyde consumption in the inhibition of the microbial growth. The development of the mathematical model considers the release dynamic of the aldehyde in the scale space. Because the release behavior is dictated by the intrinsic properties of the polymer–drug complex system, they were explained in scale space, showing that various drug release dynamics laws can be associated with scale transitions. Moreover, the functionality of a Schrödinger-type differential equation in the same scale space reveals drug release mechanisms of channels and cellular types. These mechanisms are conditioned by the intensity of the polymer–drug interactions. It was demonstrated that the proposed mathematical model confirmed a prolonged release of the aldehyde, respecting the trend established by in vitro release experiments. At the same time, the properties of the hydrogel recommend its application in patients with intrauterine adhesions (IUAs) complicated by chronic endometritis as an alternative to the traditional antibiotics or antifungals.

The word "psychedelic" (psyche (i.e., the mind or soul) and delos (i.e., to show)) has Greek origin and was first coined by psychiatrist Humphry Osmond in 1956, who had been conducting research on lysergic acid diethylamide (LSD) at the time. Psychedelic drugs such as N,N-DMT/DMT (N,N-dimethyltryptamine), 5-MeO-DMT (5-methoxy-N,N-dimethyltryptamine), LSD (lysergic acid diethylamide), MDMA (3,4-methylenedioxymethamphetamine) and psilocybin have had significant value as an entheogen in spiritual, religious (shamanic) and sociocultural rituals in Central and South American cultures for thousands of years. In the 1960s, the globalization of these drugs and their subsequent spread outside of their indigenous, old-world cultures, led to the subsequent implementation of strict drug control laws in many Western countries. Even today, psychedelics are still classified as Schedule I drugs, resulting in a still lingering negative stigmatization/perception, vilification, and ultimate criminalization of psychedelics. This controversy still lingers and still limits scientific research and full medical acceptance. For many years up until recently, the spiritual, religious and medicinal value of these drugs could not be explored in a scientific context. More recently, a second wave of psychedelic research is now focusing on psychedelics as neuropharmaceuticals to treat alcohol and tobacco addiction, general mood and anxiety disorders and cancer-related depression. There is now a vast array of promising evidence-based data to confirm the years of anecdotal evidence of the medicinal values of psychedelics. Natural therapeutic alternatives such as psychedelic drugs may provide a safe and efficacious alternate to conventional drugs used to treat mood and anxiety disorders. In a Western context in particular, psychedelic drugs as therapeutic agents for mood and anxiety disorders are becoming increasingly of interest amidst increasing rates of such disorders globally, changing social constructions, the implementation of government regulations and increasing investment opportunities, that ultimately allow for the scientific study to generate evidenced-based data. Alternative psychotherapeutic interventions are gaining interest also, because of their low physiological toxicity, relatively low abuse potential, safe psychological effects, and no associated persisting adverse physiological or psychological effects during and after use. On the other hand, conventional psychotic drugs and anti-depressants are becoming less favorable because of their adverse side effects. Psychedelic neuropharmaceutical interventions may with medical oversight be the solution to conventional psychiatric disorders such as depression and anxiety, and an alternative to conventional psychiatric treatment options. This paper will review the therapeutic potential of psychedelic drugs as alternative therapeutic options for mood and anxiety disorders in a controlled, clinical setting, where the chances of adverse psychological episodes occurring are mitigated.

Background: Regulatory assessment of anthroposophic medicinal products (AMPs) can be challenging due to their specific features. Objective: The aim of this paper is therefore to provide adequate scientific information on AMPs for regulatory purposes. Methods: A literature review was executed with database searches in PubMed, Cinahl, Merkurstab, Anthromedics, and https://iaap-pharma.org/. Search terms were: anthroposophic medicinal products, anthroposophic medicines, anthroposophic pharmacy. There was no language restriction; searches were executed from onset until June 11, 2020. In addition, experts were invited to suggest relevant literature. Results: Eighty-seven of 660 identified publications were included. The system of anthroposophic medicine (AM) with its conceptual background and various aspects of AMPs was described: definition, pharmaceutical properties, an example of AMP development, use in clinical practice, similarities with and differences to conventional medicinal products, societal aspects, scientific and regulatory assessment. Conclusion: AMPs are part of the integrative whole medical system of AM. AMPs are manufactured according to Good Manufacturing Practice and national drug regulations and have an excellent safety status; the limited available evidence suggests clinical benefits. Current drug regulation of AMPs in the EU and most European countries does not take the special properties of AMPs into account. Future research should focus on appropriate methodologies for the evaluation of effects of AMPs as part of the AM whole medical system, the scientific quality of its non-atomistic holistic ontological position, and the integration of AM and conventional medicine in clinical practice. Future policies should focus on appropriate ways of addressing regulatory challenges to AMPs. [ABSTRACT FROM AUTHOR]

A balanced approach using an integrated combination of strategies, namely, demand reduction, supply reduction and harm reduction, was suggested to be implemented in a balanced way to the policy vision of a South Africa 'free of substance abuse'. Responding on the call for a comprehensive review of the National Drug Master Plan 2013–2017 to ensure consistency in policy approach, this article explores the integrative propositional analysis (IPA)‐based analysis to evaluate 'how systemic' and integrated were the policy strategies applied. The analysis draws insights from the internal consistency of the policy and provides complementary evidence on the systemic breakdown of the policy, which correlates with previous studies. The findings are indicative of the usefulness of the IPA‐based tools to more pragmatically develop policy that better reflects the systemic/integrated relationship of the three strategies based on their conceptual systemic integrity. This research has implications for interdisciplinary scholars and practitioners, of policy and theory. [ABSTRACT FROM AUTHOR]

The article focuses on the impact of state drug testing laws on opioid therapy patients and their implications for employment-based health plans. It highlights that state drug testing laws increase testing rates among chronic pain patients prescribed opioids but have no impact on opioid prescribing rates, suggesting that these laws are an important diagnostic tool for doctors in treating employees most in need of opioid therapy.

Objective: To pilot a global policy scan assessing how governments worldwide regulate weight-loss supplements (WLS). Design: Experts on WLS policies from thirty countries that varied by World Bank income classification, with five from each of the six WHO regions, completed an online survey on WLS regulation in their country. The survey covered six domains: legal frameworks; pre-market requirements; claims, labelling, and advertisements; product availability; adverse events reporting; and monitoring and enforcement. Percentages were calculated for presence or absence of a type of regulation. Setting: Experts were recruited through websites of regulatory bodies and professional LinkedIn networks and scientific article searches on Google Scholar. Participants: Thirty experts, one from each country (i.e. researchers, regulators, other experts in food and drug regulation). Results: WLS regulations varied widely across countries, and a number of gaps were identified. One country (Nigeria) has a minimum legal age to purchase WLS. Thirteen countries reported independently evaluating the safety of a new WLS product sample. Two countries have limitations on where WLS can be sold. In eleven countries, reports on adverse events related to WLS are publicly available. In eighteen countries, safety of new WLS is to be established through scientific criteria. Penalties for WLS non-compliance with pre-market regulations exist in twelve countries and labelling requirements in sixteen countries. Conclusions: Results of this pilot study document wide variability in national WLS regulations globally, exposing many gaps in important components of consumer protection regulatory frameworks for WLS, which likely put consumer health at risk.

Dermatophytosis has acquired an epidemic-like proportion, fuelling a wide gamut of irrational, unethical and unscientific prescriptions. The menace can be attributed to poorly regulated legislative laws controlling the approval of molecules, unscientific marketing gimmicks by the pharmaceutical industry, over-the-counter availability of drugs and lack of awareness and knowledge among the prescribing physicians. In this review, we have attempted to enlist the irrational and unethical prescription patterns for dermatophytosis. [ABSTRACT FROM AUTHOR]

The so-called neurorights are emerging human rights, or rather reconfigurations of already existing human rights, seeking to address the impact of the possible misuse of neurotechnologies, which have the potential to become more invasive and harmful in the future if not regulated. The aim of specifying neurorights is to protect the dignity and autonomy of the individual in the face of neurotechnological advances. Recently, Chile proposed a Constitutional reform inspired by the neurorights, opening a debate. One of the proposed neurorights is fair and equitable access to cognitive enhancement, which will be the specific object of this perspective article. Starting from the legal proposal, we analyse and discuss some perspectives on cognitive enhancement, or “neuroenhancement”, which could be considered as part of enhancement neurotechnologies, pointing out that pharmacological enhancers, or “smart drugs”, might be considered as part of these enhancers. We present a classification of the dierent types of cognitive enhancements as it has been proposed in the literature, into which pharmacological cognitive enhancement can be included, concluding that there is currently no agreement amongst scholars and lawyers about the ethical consideration of pharmacological cognitive enhancement. We therefore argue that it is necessary for the legislator to explicitly address the issue in the proposed regulations, in order to take a clear position on the topic, as it has been done in the United Kingdom, where the pharmacological neuroenhancers have been explicitly excluded from the regulation. If pharmacological neuroenhancers are going to be considered neurotechnologies, then new law proposals should seek harmonization with the already existing legislation regulating pharmacological health and consumer rights (both globally, taking into account international drug laws, and locally, according to each country’s internal regulations) and of course, with the whole system of fundamental rights. Finally, we briefly discuss the ethical problem of equitable access to this new type of neurotechnologies (as part of the neurorights) and leave the debate open for new insights from the scientific community on the possible consequences of including (or not) pharmacological neuroenhancers as neurotechnologies for cognitive enhancement in the framework of the ethical and legal debate.

Breast cancer with bone metastasis accounts for serious cancer-associated pain which significantly reduces the quality of life of affected patients and promotes cancer progression. However, effective treatment using nanomedicine remains a formidable challenge owing to poor drug delivery efficiency to multiple cancer lesions and inappropriate management of cancer-associated pain. In this study, using engineered macrophage membrane (EMM) and drugs loaded nanoparticle, we constructed a biomimetic nanoplatform (EMM@DJHAD) for the concurrent therapy of bone metastatic breast cancer and associated pain. Tumor tropism inherited from EMM provided the targeting ability for both primary and metastatic lesions. Subsequently, the synergistic combination of decitabine and JTC801 boosted the lytic and inflammatory responses accompanied by a tumoricidal effect, which transformed the tumor into an ideal decoy for EMM, resulting in prolonged troop migration toward tumors. EMM@DJHAD exerted significant effects on tumor suppression and a pronounced analgesic effect by inhibiting μ-opioid receptors in bonemetastasismousemodels.Moreover, the nanoplatformsignificantly reduced the severe toxicity induced by chemotherapy agents. Overall, this biomimetic nanoplatform with good biocompatibility may be used for the effective treatment of breast cancer with bone metastasis. [ABSTRACT FROM AUTHOR]

Objective: The RNA-binding protein RBM10 can regulate apoptosis during the proliferation and migration of pancreatic cancer, endometrial cancer, and osteosarcoma cells; however, the molecular mechanism underlying lung adenocarcinoma is rarely reported. Recent studies have detected multiple truncated and missense mutations in RBM10 in lung adenocarcinoma, but the role of RBM10 in lung adenocarcinoma is unclear. This study mainly explored the immune regulation mechanism of RBM10 in the development of lung adenocarcinoma and its influence on sensitivity to targeted therapy drugs. Methods: The transcriptome data of CGAP were used to analyze the RNA-seq data of lung adenocarcinoma patients from different subgroups by using the CIBERSORT algorithm to infer the relative proportion of various immune infiltrating cells, and Spearman correlation analysis was performed to determine the gene expression and immune cell content. In addition, this study utilized drug trial data from the GDSC database. The IC50 estimates for each specific targeted therapy were obtained by using a regression method, and the regression and prediction accuracy were tested via ten cross-validations with the GDSC training set. An immunohistochemical test was performed on the samples of 20 patients with lung adenocarcinoma in the subcomponent analysis of immune cells, and the protein expression of RBM10 in lung adenocarcinoma tissues was verified by cellular immunofluorescence assays. Nucleic acids were extracted at low temperatures, and qRT-PCR was used to verify the expression levels of the mRNA of RBM10 in lung adenocarcinoma tissues and normal tissues (p < 0.05). Results: After screening and inclusion using a machine language, the results showed that RBM10 was significantly highly expressed in the lung adenocarcinoma tissues. The related signaling pathways were mainly concentrated in ncRNA processing, rRNA metabolic processes, ribosome biogenesis, and the regulation of translation. The qRT-PCR for 20 lung adenocarcinoma tissues showed that the expression of RBM10 in these tissues was significantly different from that in normal tissues (p = 0.0255). Immunohistochemistry analysis and cell immunofluorescence staining also confirmed that RBM10 was involved in the immune regulation of lung adenocarcinoma tissues, and the number of immune cell aggregations was significantly higher than that of the control group. RBM10 regulates B cell memory-CIBERSORT (p = 0.042) and B cell memory-CIBERSOTRT-abs (p = 0.027), cancer-associated fibroblast-EPIC (p = 0.001), cancer-associated fibroblast- MCPCounter (p = 0.0037), etc. The risk score was significantly associated with the sensitivity of patients to lapatinib (p = 0.049), nilotinib (p = 0.015), pazopanib (p = 0.001), and sorafenib (p = 0.048). Conclusions: RBM10 can inhibit the proliferation and invasion of lung adenocarcinoma cells through negative regulation and promote the apoptosis of lung adenocarcinoma cells through immunomodulatory mechanisms. The expression level of RBM10 affects the efficacy of targeted drug therapy and the survival prognosis of lung adenocarcinoma patients, which has a certain guiding significance for the clinical treatment of these patients.

Purpose: Access to medication for opioid use disorder (MOUD) varies across the rural-urban continuum. The Hub & Spoke Model (H&S) emerged to address these gaps in service whereby hubs with staff expertise in MOUD support delivery of specialized care to a network of spoke locations, often located in rural communities with workforce shortages. This paper presents a case study of efforts to implement the hub and spoke model in a frontier and rural (FAR) state: Montana. Methods: The primary data are structured interviews with 65 MOUD program staff in hub and spoke locations within Montana. Both inductive and deductive coding were used to analyze the transcripts. Findings: Using the H&S structure to expand access to MOUD in Montana led to mixed results. There were consistent themes identified in the interviews about the reasons why hubs struggled to successfully recruit spokes, including (1) geographic barriers, (2) a lack of interest among medical providers, (3) fears about excessive demand, (4) concerns about the financial viability of the model, and (5) a preference for informal technical assistance rather than a formal H&S relationship. In addition to these 5 themes, efforts to implement H&S across different medical systems were unsuccessful, whereas the H&S model worked more effectively when H&S locations were within the same organization. Conclusion: This case study identified limits to the H&S model utility in supporting states' abilities to expand access to MOUD treatment and offers suggestions for adapting it to accommodate variation across divergent rural contexts. We conclude with recommendations for strategies that may assist in expansion of MOUD in rural communities that are like those found in Montana. [ABSTRACT FROM AUTHOR]

In 2021, during a drug-related death crisis in the UK, the Government published its ten-year drugs strategy. This article, written in collaboration with the Faculty of Public Health and the Association of Directors of Public Health, assesses whether this Strategy is evidence-based and consistent with international calls to promote public health approaches to drugs, which put 'people, health and human rights at the centre'. Elements of the Strategy are welcome, including the promise of significant funding for drug treatment services, the effects of which will depend on how it is utilized by services and local commissioners and whether it is sustained. However, unevidenced and harmful measures to deter drug use by means of punishment continue to be promoted, which will have deleterious impacts on people who use drugs. An effective public health approach to drugs should tackle population-level risk factors, which may predispose to harmful patterns of drug use, including adverse childhood experiences and socioeconomic deprivation, and institute evidence-based measures to mitigate drug-related harm. This would likely be more effective, and just, than the continuation of policies rooted in enforcement. A more dramatic re-orientation of UK drug policy than that offered by the Strategy is overdue.

The recent benefit–risk framework (BRF) developed by the Food and Drug Administration (FDA) is intended to improve the clarity and consistency in communicating the reasoning behind the FDA's decisions, acting as an important advancement in US drug regulation. In the PDUFA VI implementation plan, the FDA states that it will continue to explore more structured or quantitative decision analysis approaches; however, it restricts their use within the current BRF that is purely qualitative. By contrast, European regulators and researchers have been long exploring the use of quantitative decision analysis approaches for evaluating drug benefit–risk balance. In this paper, we show how quantitative modelling, backed by decision theory, could complement and extend the FDA's BRF to better support the appraisal of evidence and improve decision outcomes. After providing relevant scientific definitions for benefit–risk assessment and describing the FDA and European Medicines Agency (EMA) frameworks, we explain the components of and differences between qualitative and quantitative approaches. We present lessons learned from the EMA experience with the use of quantitative modelling and we provide evidence of its benefits, illustrated by a real case study that helped to resolve differences of judgements among EMA regulators.

Background: The rapid expansion and anticipated U.S Food and Drug Administration regulation of 3D printing at the point-of-care necessitates the creation of robust quality management systems. A critical component of any quality management system is a document control system for the organization, tracking, signature collection, and distribution of manufacturing documentation. While off-the-shelf solutions for document control exist, external programs are costly and come with network security concerns. Here, we present our internally developed, cost-effective solution for an electronic document control system for 3D printing at the point-of-care. Methods: We created a hybrid document control system by linking two commercially available platforms, Microsoft SharePoint and Adobe Sign, using a customized document approval workflow. Results: Our platform meets all Code of Federal Regulations Title 21, Part 11 guidances. Conclusion: Our hybrid solution for document control provides an affordable system for users to sort, manage, store, edit, and sign documents. The system can serve as a framework for other 3D printing programs to prepare for future U.S Food and Drug Administration regulation, improve the efficiency of 3D printing at the point-of-care, and enhance the quality of work produced by their respective program.

It has been 3 years since China implemented new management regulations for drug clinical trial institutions in December 2019, the most important of which is to change the qualification recognition of drug clinical trial institutions into recordkeeping system. The original intention of the institution record-keeping system was to solve the shortage of clinical trial resources in China, effectively expand the number of clinical trial institutions, and effectively alleviate the contradiction between medical treatment and scientific research. After implementing the record-keeping system, although these goals have been achieved to a certain extent, there are still areas worthy of optimization and improvement. Therefore, we evaluated the new process, in particular the requirements, in order to see what possible barriers in the record-keeping system of institutions. We find that the requirements for principal investigator (PI) qualifications are the key to the recordkeeping system. This reflects the shift of Chinese regulators' supervision of clinical trials to supervision of the ability to conduct clinical trials. However, the ambiguity of the definition of PI qualification has hindered implementation of the recordkeeping system and reduced the release of clinical trial resources. [ABSTRACT FROM AUTHOR]

Drugs are increasingly authorized based on less mature evidence, leaving payors faced with significant clinical and cost-effectiveness uncertainties. As a result, payors must often choose between reimbursing a drug that may not turn out to be cost-effective (or may even be unsafe) or delaying the reimbursement of a drug that is cost-effective and offers clinical benefit to patients. Novel reimbursement decision models and frameworks, such as managed access agreements (MAAs), may address this decision challenge. Here, we provide a comprehensive overview of the legal limitations, considerations, and implications for adopting MAAs in Canadian jurisdictions. We begin with an overview of current drug reimbursement processes in Canada, terminology and definitions of the different types of MAAs, and select international experiences with MAAs. We discuss the legal barriers to MAA governance frameworks, design and implementation considerations, and legal and policy implications of MAAs. Finally, we provide recommendations to guide policy development for implementing MAAs in Canada, based on existing literature, international experience, and our legal analysis. We conclude that legal and policy barriers likely prevent the adoption of a pan-Canadian MAA governance framework. More feasible is a quasi-federal or provincial approach, building on existing infrastructure. [ABSTRACT FROM AUTHOR]

Over the past 25 years, Congress and the FDA have determined the safest and most beneficial way to regulate the use of mifepristone (Mifeprex), the medication that accounts for the majority of abortions in the United States. The Dobbs decision has renewed the importance of those scientific determinations, especially FDA's decisions implementing the Risk Evaluation and Mitigation Strategy (REMS) provisions of the Federal Food Drug and Cosmetic Act (FDCA), that mifepristone may be taken by patients outside the presence of any healthcare provider (often through telemedicine prescription and shipment across state lines). Now that Dobbs has been decided, state officials have indicated that they will seek to enforce state statutes which conflict with FDA's regimen for the proper use of mifepristone, by banning its use entirely, prohibiting telemedicine prescription, or imposing other requirements which FDA has specifically considered and now rejected as contrary to the congressional mandate that FDA-approved drugs be as accessible as safety considerations allow. Litigation has already been filed to invalidate such statutes on the grounds that they are preempted by the doctrine that state law which conflicts with, or undermines the purposes of, FDA actions with respect to approved drugs are preempted under the Supremacy Clause of the Constitution. This article examines the Supreme Court caselaw and FDA actions which will dictate the outcome of that litigation. Part I details the statutory basis for FDA preemption of conflicting state law and the four decisions by the Supreme Court over the last 13 years (Levine, Mensing, Bartlett and Albrecht) which enunciate the governing legal standards for FDA preemption. We pay particular attention to the opinions of Justice Alito and the other conservative justices, which hold that such FDA preemption should be robust to ensure that there is one consistent, national policy for the distribution and regulation of drugs, under the science-based decisions of the FDA, rather than the 'parochialism' of differing state standards. Part II details FDA's comprehensive program for the balanced, though appropriately restricted, use of mifepristone, and the 22 years of FDA actions that brought that about. It then catalogs the state statutes limiting the use of the drug which, in material ways, conflict with those FDA determinations. Part III outlines the arguments made in one early lawsuit seeking preemption of the statutes of one state (Mississippi)–a law suit which previews the wider litigation to come. It then sets forth the strong arguments for FDA preemption of each type of state restriction and responses to the 'defenses' of those statutes that have been offered in an effort to avoid FDA preemption under the Supremacy Clause. That review shows that a straight-forward application of the FDCA and the Supreme Court caselaw should result in the preemption of the state restrictions that squarely conflict with the relatively free access to abortion medications which FDA has mandated.

Background: In the past decades, economic sanctions imposed on Iran for its nuclear program. The embargo made difficulty in foreign trade and led to lack of timely access to medicines. As the internationally-led sanctions caused to the shortage of medicine there, healthcare systems need to applied the new policies for maintaining health service quality especially in pharmaceutical sector. Objectives: This paper is about policies applied in Iran health system during the crisis reached its peak in 2012 as a good experience for guarantying access to pharmaceutical products. Methods: Through interviewing experts and managers in pharmaceutical regulatory system, the implemented policies in targeted historical period were extracted, then quantitative data were analyzed to show the impact of the policies on the access and affordability of medicines before and after their implementation in Iran food and drug administration (IFDA). This paper tries to show strategies employed by to tackle the crisis caused by sanctions and to offer practical policies to make medicines more accessible at the time of crisis. Results: In order to reduce the harmful effects of this crisis, IFDA proposed some changes at different levels ranging from organizational procedures to parliament legislations. The main achievements of IFDA were making drugs easily available are as follows, significantly reducing prices, decreasing the share of market regarding the imported medicines, facilitating the manufacture of domestic medicines, encouraging foreign investment in manufacturing drugs domestically, controlling the shortage of drugs, and finally giving financial support to all patients in general and to those patients who had problem paying for drugs in particular. Conclusion: These experiences which made the Iran pharmaceutical sector survive during the international sanctions, can be considered as a good example of resilience strategies in similar situations.

Collective efforts among governments and regional organizations is a vital part of the fight against piracy that represents a security threat to all nationstates with respect to freedom to navigate the high seas. This paper provides a concise overview of piracy, contemporary maritime drug laws, and cases among the circuit courts to illustrate the procedural concerns that affect fundamental constitutional principles of jurisdiction. A possible solution to existing substantive and procedural due process issues is establishment of a regional judicial institution with broad powers to preside over criminal prosecutions that include maritime crimes. The suggestion may be a viable means to resolve some concerns with respect to jurisdictional principles, regional stability, and the need for a comprehensive, coordinated response within the Western Hemisphere. Establishing a tribunal to preside over enforcement practices alleviates dependency on the existing legal framework that may not fully resolve jurisdictional issues associated with maritime drug trafficking. In addition, a regional tribunal minimizes the need for the United States to function as the only viable, sovereign nation-state in the Americas to ensure that pirates engaged in illicit trades are not roaming the high seas with impunity.

Cannabidiol (CBD) product regulatory efforts must be informed by research regarding consumer perceptions. This mixed-methods study examined CBD product information sources, knowledge, perceptions, use and use intentions among young adults. This study analyzed (i) Fall 2020 survey data from 2464 US young adults (M age = 24.67, 51.4% ever users, 32.0% past 6-month users) and (ii) Spring 2021 qualitative interviews among 40 survey participants (27.5% past-month users). Overall, 97.9% of survey participants reported having heard of CBD, 51.4% ever/lifetime use and 32.0% past 6-month use. Survey participants learned about CBD from friends/family (58.9%), products/ads at retailers (36.4%), online content/ads (34.8%), CBD stores (27.5%) and social media (26.7%). One-fourth believed that CBD products were required to be US Food and Drug Administration-approved (24.9%), tested for safety (28.8%) and proven effective to be marketed for pain, anxiety, sleep, etc. (27.2%). Survey and interview participants perceived CBD as safe, socially acceptable and effective for addressing pain, anxiety and sleep. Interview findings expanded on prominent sources of marketing and product exposure, including online and specialty retailers (e.g. vape shops), and on participants' concerns regarding limited regulation and/or evidence regarding CBD's effectiveness/risks. Given young adults' misperceptions about CBD, surveillance of CBD knowledge, perceptions and use is critical as the CBD market expands. [ABSTRACT FROM AUTHOR]

Drugs administered to children in the United States fall into two broad categories: (1) those that have followed the US Food and Drug Administration (US-FDA) pediatric drug approval process and are marketed as finished dosage forms with pediatric labeling; and (2) all others, many of which are used "off-label". The use of most drug products in pediatrics is still off label, often requiring special preparation, packaging, and, in some cases, compounding into preparations. The latter category includes compounded preparations that incorporate either a US-FDA approved finished dosage form (e.g., a sterile solution, sterile powder, nonsterile capsules, oral solution, crushed tablets, etc.), or rely on bulk active pharmaceutical ingredients (APIs). Compounded preparations are prepared for individual patients in 503A pharmacies, or on a larger scale and not just for specific patients, in licensed 503B establishments. Critical gaps in the current drug approval process for finished dosage forms have created a proverbial "Gordian knot" that needs to be untangled thoughtfully to facilitate increased production and approval of vitally needed medications for pediatric patients. This opinion will describe current regulatory processes pertaining to pediatrics-only drug approval in the United States. Additionally, discussed are steps required for a product to acquire pediatric labeling. Gaps in regulatory approval pathways for both manufactured and compounded pediatric drugs will be identified, especially those that complicate and slow development and availability to patients. Finally, suggestions for regulatory modifications that may enhance pediatric product development strategies for both manufacturers and compounders are suggested. [ABSTRACT FROM AUTHOR]

Bacterial drug resistance is one of the major challenges to present and future human health, as the continuous selection of multidrug resistant bacteria poses at serious risk the possibility to treat infectious diseases in the near future. One of the infection at higher risk to become incurable is tuberculosis, due to the few drugs available in the market against Mycobacterium tuberculosis. Drug resistance in this species is usually due to point mutations in the drug target or in proteins required to activate prodrugs. However, another interesting and underexplored aspect of bacterial physiology with important impact on drug susceptibility is represented by the changes in transcriptional regulation following drug exposure. The main regulators involved in this phenomenon in M. tuberculosis are the sigma factors, and regulators belonging to the WhiB, GntR, XRE, Mar and TetR families. Better understanding the impact of these regulators in survival to drug treatment might contribute to identify new drug targets and/or to design new strategies of intervention.

The development of specific drug therapy for children was a paradigm‐changing event that transformed paediatric medical practice. However, a series of tragedies involving drug treatment for children resulted in a gap developing between drug regulation and practice, with the majority of drugs used in child healthcare being used off‐label, rendering children therapeutic orphans. Over the past two decades changes in drug regulation led by the US Food and Drug Administration and followed by the European Union's European Medicines Agency have led to substantial changes in how new drugs with potential use in children are studied and labelled. While these changes have substantially improved labelling for new drugs, there has been much less progress with older drugs. Although the unique challenges of conducting clinical research in children have been addressed by novel clinical trial designs, many of these innovations have not been translated into approaches accepted for the drug approval process. The regulations applying to the need for paediatric studies currently are only applicable in the United States and the European Union, and there is less impetus for paediatric labelling in other jurisdictions. This impacts on a number of issues beyond labelling, including the availability of child‐friendly formulations. Finally, the impact of Brexit on paediatric drug studies in the UK remains unclear and is subject to ongoing negotiations between the UK government and the European Union. [ABSTRACT FROM AUTHOR]

Overdose Good Samaritan laws (GSLs) aim to reduce mortality by providing limited legal protections when a bystander to a possible drug overdose summons help. Most research into the impact of these laws is dated or potentially confounded by coenacted naloxone access laws. Lack of awareness and trust in GSL protections, as well as fear of police involvement and legal repercussions, remain key deterrents to help-seeking. These barriers may be unequally distributed by race/ethnicity due to racist policing and drug policies, potentially producing racial/ethnic disparities in the effectiveness of GSLs for reducing overdose mortality. We used 2015–2019 vital statistics data to estimate the effect of recent GSLs on overdose mortality, overall (8 states) and by Black/White race/ethnicity (4 states). Given GSLs' near ubiquity, few unexposed states were available for comparison. Therefore, we generated an "inverted" synthetic control method (SCM) to compare overdose mortality in new-GSL states with that in states that had GSLs throughout the analytical period. The estimated relationships between GSLs and overdose mortality, both overall and stratified by Black/White race/ethnicity, were consistent with chance. An absence of effect could result from insufficient protection provided by the laws, insufficient awareness of them, and/or reticence to summon help not addressable by legal protections. The inverted SCM may be useful for evaluating other widespread policies. [ABSTRACT FROM AUTHOR]

Background: This paper has set out to map the state of pharmaceutical regulation in the developing world through the construction of cross-national indices drawing from World Health Organization data. The last two decades have been characterized by deep changes for the pharmaceutical sector, including the complete transformation of intellectual property systems at the behest of the World Trade Organization and the consolidation of global active ingredient suppliers in China and India. Although the rules for ownership of medicine have been set and globally implemented, we know surprisingly little about how the standards for market entrance and regulation of pharmaceutical products have changed at the national level. How standardized are national pharmaceutical market systems? Do we find homogeneity or variation across the developing world? Are their patterns for understanding why some countries have moved closer to one global norm for pharmaceutical regulation and others have developed hybrid models for oversight of this sector? Access to medicine is a core tool in public health. This paper gauges the levels of standards in public and private generics markets for developing countries building on national-level pharmaceutical market surveys for 78 countries to offer three indicators of market oversight: State Regulatory Infrastructure, Monitoring the Private Market and Public Quality Control. Identifying the different variables that affect a state's institutional capacity and current standard level offers new insights to the state of pharmaceuticals in the developing world. It is notable that there are very few (none at the time of this paper) studies that map out the new global terrain for pharmaceutical regulation in the post-TRIPS context.Results: This paper uses item response theory to develop original indicators of pharmaceutical regulation. We find remarkable resistance to the implementation of global pharmaceutical norms for quality standards in developing states and in regulatory infrastructure. Human capacity across many developing countries remains limited. Most notably, variation among states is stark. Countries that have been leaders in establishing global norms do not appear to have influenced their neighbors in establishing regional patterns. Finally, in contrast to traditional theories of international norms diffusion, global standard-setters such as the United States or European Union appear to have surprisingly little influence on standard setting across our survey.Conclusions: Our research has implications for the framing of technical support on public health initiatives aimed at strengthening local public institutions in medicine and offers a new methodological approach for analyzing drug regulation systems in developing countries.

Background: Antibiotics have played an essential role in decreasing morbidity and mortality from infectious diseases. However, indiscriminate use and unrestricted access is contributing to the emergence of bacterial resistance. This paper reports on a situational analysis of antimicrobial use and resistance in Ghana, with focus on policy and regulation.Methods: Relevant policy documents, reports, regulations and enactments were reviewed. PubMed and Google search engines were used to extract relevant published papers. Websites of stakeholders such as Ministry of Health (MOH) and its agencies were also reviewed. An interview guide was used to elicit responses from selected officials from these sectors.Results: Laws and guidelines to control the use of antimicrobials in humans were available but not for animals. There was no National Antimicrobial Policy (NAP). A health practice regulatory law mandates Physicians, Physician Assistants, Midwives and trained Nurses to prescribe antimicrobials. However, antibiotics are widely prescribed and dispensed by unauthorised persons, suggesting weak enforcement of the laws. Antibiotics were also supplied to and from unapproved medicine outlets. The Standard Treatment Guidelines (STG), Essential Medicines List (EML) and the National Health Insurance Scheme Medicines List (NHISML) provide restrictions regarding levels of prescribing of antimicrobials. However, existing guidelines on antibiotic use are mostly not adhered to. The use of Automatic Stop Orders to avoid wastage in the hospitals is also not practiced. Data on use of antibiotics for individuals are not readily available in most facilities. Again, there are no standards or guidelines on veterinary use of antibiotics. Surveillance systems for consumption of antibiotics and resistance monitoring were not in place in most health facilities. However, there is an ongoing national action to create awareness on bacteria resistance, strengthening knowledge through research and surveillance and development of NAP in line with global action plan on antimicrobial resistance.Conclusion: Absence of national antimicrobial policy, weak regulatory environment and non-adherence to practice standards may have contributed to increased and unregulated access to antimicrobials in Ghana, a catalyst for development and spread of antimicrobial resistance.

Recently, many studies have shown that lncRNA can mediate the regulation of TF-gene in drug sensitivity. However, there is still a lack of systematic identification of lncRNA-TF-gene regulatory triplets for drug sensitivity. In this study, we propose a novel analytic approach to systematically identify the lncRNA-TF-gene regulatory triplets related to the drug sensitivity by integrating transcriptome data and drug sensitivity data. Totally, 1570 drug sensitivity-related lncRNA-TF-gene triplets were identified, and 16 307 relationships were formed between drugs and triplets. Then, a comprehensive characterization was performed. Drug sensitivity-related triplets affect a variety of biological functions including drug response-related pathways. Phenotypic similarity analysis showed that the drugs with many shared triplets had high similarity in their two-dimensional structures and indications. In addition, Network analysis revealed the diverse regulation mechanism of lncRNAs in different drugs. Also, survival analysis indicated that lncRNA-TF-gene triplets related to the drug sensitivity could be candidate prognostic biomarkers for clinical applications. Next, using the random walk algorithm, the results of which we screen therapeutic drugs for patients across three cancer types showed high accuracy in the drug-cell line heterogeneity network based on the identified triplets. Besides, we developed a user-friendly web interface-DrugSETs (http://bio-bigdata.hrbmu.edu.cn/DrugSETs/) available to explore 1570 lncRNA-TF-gene triplets relevant with 282 drugs. It can also submit a patient's expression profile to predict therapeutic drugs conveniently. In summary, our research may promote the study of lncRNAs in the drug resistance mechanism and improve the effectiveness of treatment. [ABSTRACT FROM AUTHOR]

Introduction: TETRAXIM™ (Sanofi), a combined diphtheria, tetanus, acellular pertussis, and inactivated poliovirus (DTaP-IPV) vaccine, has been licensed in South Korea since 2009. In accordance with the Ministry of Food and Drug Safety regulations, this post-marketing surveillance (PMS) study evaluated the safety of the DTaP-IPV vaccine in real-world clinical practice in infants and children who received it as either a part of the three-dose primary series dose at 2, 4, and 6 months or school entry booster between 4 and 6 years of age. Methods: This multicenter, observational, PMS study was conducted in real-world practice in South Korea for 6 years (2009–2015) in participants aged between 2 months and 6 years. The study outcomes included solicited reactions, unsolicited adverse events (AEs)/adverse drug reactions (ADRs), unexpected AEs/ADRs, and serious AEs (SAEs)/ADRs. Results: Data from 647 participants was included in the safety analysis. Overall, 268 AEs were reported by 181 (28%) participants: 47 (17.5%) solicited reactions, 220 (82.1%) unsolicited AEs, and 1 (0.4%) unsolicited ADR. A total of 48 AEs (including 47 solicited reactions) were reported to have a causal relationship with the DTaP-IPV vaccine and were reported by 36 (5.6%) participants. A total of 212 unexpected AEs were reported by 152 (23.5%) participants, none of which had a causal relationship with the DTaP-IPV vaccine. Neither immediate AEs nor SAEs were reported during the study. Among the participants who reported AEs, 220 (34%) were on concomitant medications. Most AEs were of mild intensity, and all participants recovered. Conclusion: No safety concerns related to the DTaP-IPV vaccine in a real-world setting were raised in participants aged 2–6 months for the primary series and 4–6 years for the school-entry booster dose in the Korean population. The DTaP-IPV vaccine was well tolerated and can be continued as part of routine immunization programs in infants and children. Trial Registration: NCT01437423. [ABSTRACT FROM AUTHOR]
