How New Drugs Are Discovered and Developed

Abstract

Drug discovery and development is a complex, multidisciplinary process that transforms a scientific concept into a safe and effective therapeutic product, encompassing target identification and validation, hit discovery, lead optimization, preclinical studies, clinical trials, and eventual regulatory approval. Over the past two decades, India has emerged as a significant center for pharmaceutical research and innovation, supported by a strong generic drug industry, advanced contract research organizations, and expanding academia & industry collaborations. However, translating laboratory research into marketable medicines requires strict adherence to regulatory standards to ensure safety, efficacy, and quality. In India, the Central Drugs Standard Control Organization (CDSCO), operating under the Drugs and Cosmetics Act, 1940 and its amendments, serves as the national regulatory authority, while the New Drugs and Clinical Trials Rules, 2019 have streamlined approval procedures, strengthened compliance with Good Clinical Practice guidelines, and aligned domestic regulatory processes with international standards. Despite persistent challenges such as high attrition rates, regulatory complexities, and funding limitations, India continues to enhance its translational research infrastructure and global regulatory compliance, progressively advancing an ecosystem that balances innovation with stringent quality and safety requirements to address unmet medical needs.
