REGULATORY AFFAIRS IN PHARMACEUTICAL PRODUCT DEVELOPMENT: A COMPREHENSIVE REVIEW

Abstract

Pharmaceutical product development is a complex and highly regulated process that ensures medicines are safe, effective, and of high quality before they reach patients. Regulatory affairs play a central role in coordinating scientific, technical, and legal requirements throughout the product life cycle, from early research and development to post-marketing surveillance. Regulatory professionals work closely with research, manufacturing, quality assurance, and clinical teams to ensure compliance with national and international regulations. They are responsible for preparing regulatory submissions, maintaining communication with health authorities, and ensuring that pharmaceutical products meet applicable standards for approval and marketing. In recent years, globalization, harmonization of regulatory guidelines, and advances in digital technologies have significantly influenced regulatory practices. This review highlights the importance of regulatory affairs in pharmaceutical product development, discusses the major regulatory authorities and essential guidelines, outlines key regulatory responsibilities during product development, and summarizes current challenges and future perspectives in the field.
