Pharmacovigilance (PV) plays an analytical role in ensuring drug safety and public health. This research explores the regulatory frameworks and PV systems in India and Japan, focusing on the Central Drugs Standard Control Organization (CDSCO) and Pharmaceuticals and Medical Devices Agency (PMDA), respectively. Historical developments, adverse drug reaction (ADR) reporting systems, risk management protocols, and international harmonization practices are discussed.1 India's PV system has evolved through programs such as the Pharmacovigilance Program of India (PvPI), whereas Japan’s system emphasizes structured post-marketing surveillance (PMS) and risk management plans (RMPs). Although both systems have made significant progress, challenges such as underreporting in India and regulatory burden in Japan persist. This comparative analysis offers insights into upgrading global pharmacovigilance through interactive learning and harmonization.
