PHARMACEUTICAL ANALYSIS AND QUALITY ASSURANCE IN DRUG DEVELOPMENT: EMERGING TECHNIQUES, REGULATORY FRAMEWORK, AND MODERN INNOVATIONS

Abstract

Pharmaceutical analysis and quality assurance (QA) are fundamental pillars of the pharmaceutical industry, ensuring the safety, efficacy, purity, and consistency of drug products. With increasing complexity in modern drug formulations, including biologics, nanomedicines, and combination therapies, advanced analytical and quality systems have become essential. Pharmaceutical analysis involves the identification, quantification, and purity assessment of drugs using classical and instrumental methods, while quality assurance ensures that all manufacturing processes comply with regulatory standards such as Good Manufacturing Practices (GMP). Recent innovations such as hyphenated techniques (LC-MS, GC-MS), quality by design (QbD), process analytical technology (PAT), and artificial intelligence-based quality monitoring have significantly improved drug development efficiency. This review discusses the principles of pharmaceutical analysis, modern analytical techniques, QA systems, validation protocols, regulatory guidelines, and emerging trends shaping the future of pharmaceutical quality systems.
