Pharmacovigilance and materiovigilance
One line
The Indian Pharmacopoeia Commission and Andhra Pradesh MedTech Zone convened national monitoring centres to strengthen drug and medical-device safety surveillance.
Summary
Clinical trials cannot detect every rare or long-term adverse event. Post-market surveillance collects and analyses reports after products enter widespread use and can trigger warnings, label changes, recalls, or regulatory action.
PYQ pattern
UPSC may connect pharmaceutical regulation with trials, quality control, adverse-event reporting, and public trust. Review the official UPSC question-paper archive.
