The history and development of pharmacovigilance trace how drug safety evolved from the thalidomide tragedy to sophisticated global systems. This introduction covers key milestones, regulatory initiatives, WHO programmes, Uppsala Monitoring Centre, signal detection, causality assessment (Naranjo, WHO‑UMC), MedDRA coding, spontaneous reporting, post‑marketing surveillance (Phase IV), risk management plans, pharmacovigilance legislation and national programmes like PvPI. B. Pharm students will learn essential terms—adverse drug reaction (ADR), signal, disproportionality analysis, PSUR/PBRER, EudraVigilance—and the roles of industry, regulators and healthcare professionals. Practical understanding helps in reporting, analysis and patient safety. Now let’s test your knowledge with 30 MCQs on this topic.
