As drug development continues to evolve, regulatory expectations are becoming increasingly focused on scientific rigor, product quality, and reliable clinical evidence. Two recently published U.S. Food and Drug Administration (FDA) guidances address important areas of pharmaceutical development—clinical investigations for psychedelic drugs and bioequivalence evaluation of topical dermatologic corticosteroids. While these guidances focus on different therapeutic areas, both em

Before submitting an Over-the-Counter (OTC) Monograph Order Request (OMOR) or advancing the development of an OTC monograph drug, early engagement with the U.S. Food and Drug Administration (FDA) can help sponsors clarify regulatory expectations, discuss scientific evidence, and address potential development challenges. Structured interactions with the Agency allow sponsors to obtain timely feedback, improve development planning, and support efficient regulatory decision-maki

Before approving a New Drug Application (NDA) or Abbreviated New Drug Application (ANDA), the U.S. Food and Drug Administration (FDA) must ensure that the manufacturing facilities are capable of consistently producing medicines that meet Current Good Manufacturing Practice (CGMP) requirements. Preapproval Inspections (PAIs) are conducted to evaluate manufacturing readiness, verify the accuracy of Chemistry, Manufacturing and Controls (CMC) information, and confirm that facili

Innovation is transforming medicinal product development through the introduction of novel methodologies such as biomarkers, digital health technologies, artificial intelligence (AI), modelling and simulation, real-world data, patient registries, and advanced non-clinical testing methods. These approaches have the potential to improve evidence generation, streamline drug development, and support more informed regulatory decision-making. However, before they can be widely adop

Timely access to innovative medicines and biosimilars is an important objective for regulatory authorities worldwide. Collaborative assessment models enable regulators to share scientific expertise, reduce duplication of effort, and accelerate the availability of high-quality, safe, and effective medicines for patients. International work-sharing initiatives also promote regulatory convergence while maintaining robust scientific evaluation standards. The Medicines and Healthc

Access to accurate and up-to-date medicinal product information is essential for the safe prescribing, dispensing, and use of medicines. Healthcare professionals rely on authorised product information to make informed clinical decisions, while patients depend on clear instructions to use medicines safely and effectively. Providing easy access to approved regulatory information also promotes transparency throughout a medicine's lifecycle. The Medicines and Healthcare products

Pharmacovigilance plays a critical role in protecting public health by enabling the timely identification, assessment, and management of medicine safety concerns. Accurate reporting of adverse drug reactions (ADRs) and Adverse Events Following Immunisation (AEFIs) allows regulatory authorities to continuously monitor the benefit-risk profile of authorised medicines and implement appropriate regulatory actions when necessary. To strengthen electronic pharmacovigilance reportin

Artificial Intelligence (AI) is rapidly transforming drug development by enabling more efficient data analysis, predictive modelling, and evidence-based decision-making. Early-phase clinical trials, particularly Phase 1 studies, represent one of the most challenging stages of drug development due to uncertainties surrounding dose selection, patient recruitment, safety monitoring, and progression decisions. Improving the efficiency of these trials has the potential to accelera

Marketing Authorisations (MAs) require updates throughout a medicine's lifecycle to reflect changes in manufacturing, quality, safety, efficacy, product information, or administrative details. To ensure that these changes are appropriately assessed and approved while maintaining product quality and patient safety, the Medicines and Healthcare products Regulatory Agency (MHRA) provides detailed guidance on applying for variations to UK Marketing Authorisations. The MHRA guidan

Medicines labelling and packaging are fundamental to the safe and effective use of medicines. Clear packaging enables patients, carers, pharmacists, and healthcare professionals to correctly identify medicines, understand essential safety information, and minimise the risk of medication errors. Poor label design, confusing layouts, or lookalike packaging can contribute to dispensing mistakes and inappropriate medicine use. To promote consistent and patient-focused packaging,

Medicines packaging, labelling, and Patient Information Leaflets (PILs) are essential components of medicine safety and regulatory compliance. They provide healthcare professionals and patients with critical information regarding the safe use, storage, administration, and identification of medicinal products. Throughout a medicine's lifecycle, these materials must remain accurate, up to date, and consistent with the approved product information to support patient safety and r

Next-generation sequencing (NGS) has become an essential tool in antiviral drug development, enabling detailed analysis of viral genetic changes and the identification of resistance-associated variants. Compared with traditional sequencing methods, NGS generates extensive sequence data that provides a deeper understanding of viral populations throughout clinical development. To promote consistent and high-quality regulatory submissions, the U.S. Food and Drug Administration (

Maintaining the safety of the blood supply is a critical public health priority, particularly during outbreaks of emerging infectious diseases. Ebola disease, caused by viruses of the Orthoebolavirus genus, is associated with severe illness and can be transmitted through direct contact with infected body fluids. Although transfusion-transmitted Ebola disease has not been widely documented, the potential risk of transmission through blood and blood components requires appropri

Determining whether a product qualifies as a medical device is one of the most important regulatory decisions for manufacturers before placing a product on the Great Britain market. Many products fall into a "borderline" category because they may share characteristics with medicines, cosmetics, food supplements, biocides, personal protective equipment (PPE), or other regulated products. To provide greater regulatory clarity, the Medicines and Healthcare products Regulatory Ag

As regulatory systems become increasingly digital, standardized medicinal product data has become essential for improving regulatory efficiency and ensuring consistent information across the European medicines network. To support this transition, the European Medicines Agency (EMA) published the guidance Product Management Services (PMS) – Implementation of ISO Standards for the Identification of Medicinal Products (IDMP) in Europe – Chapter 3: Process for the Electronic Subm

Environmental sustainability is becoming an essential consideration in pharmaceutical manufacturing as production activities consume significant amounts of energy, water, raw materials, and solvents while generating emissions, effluents, and waste. These activities can affect ecosystems, contribute to climate change, and influence long-term public health. To help manufacturers integrate sustainable practices into pharmaceutical operations, the World Health Organization (WHO)

Manufacturers who intend to place medical devices on the market in Great Britain or Northern Ireland must comply with the registration requirements established by the Medicines and Healthcare products Regulatory Agency (MHRA). The Register Medical Devices to Place on the Market guidance explains which devices require registration, who is responsible for registration, applicable timelines, registration procedures, and the associated fees. It also outlines the differences in re

Clinical trials have traditionally been conducted using separate protocols to evaluate individual drugs for specific diseases or patient populations. While this approach has contributed significantly to medical innovation, it can be resource-intensive, time-consuming, and challenging when studying rare diseases or rapidly evolving therapeutic areas. To improve the efficiency of clinical development, the FDA issued the draft guidance "Master Protocols for Drug and Biological P

Demonstrating that a drug works as intended is one of the most important requirements for FDA approval. Before a new drug or biological product can reach patients, sponsors must provide strong scientific evidence showing that the product delivers meaningful clinical benefits. To clarify current expectations, the FDA issued the draft guidance "Demonstrating Substantial Evidence of Effectiveness for Human Drug and Biological Products." The guidance explains how sponsors can est

Selecting an appropriate starting dose for first-in-human (FIH) clinical trials is one of the most critical decisions in drug development. An initial dose that is too high may expose participants to unnecessary safety risks, while a dose that is too low may provide limited scientific value and delay clinical development. To support safer and more informed dose selection, the FDA released the draft guidance "Quantitative Systems Pharmacology (QSP)-Based Dose Selection for Mini
