Post Marketing Surveillance (PMS)

Post marketing surveillance (PMS) is the practice of monitoring the safety of a pharmaceutical drug or device after it has been relapsed on the market and is an important part of the science of Pharmacovigilance.

Post-marketing surveillance is important because at the time a drug is approved for marketing a number of clinically and epidemiologically important questions are unanswered. Post-marketing surveillance of drugs therefore plays an important role to discover undesirable effects that might present a risk. Post-marketing surveillance studies provide additional information on the benefits and risks of a drug, resulting in possible drug safety hazards being identified which impact on, or may influence the overall benefit/risk ratio of a medicinal product.

PMS used as a number of approaches to monitor the safety of license drugs including spontaneous reporting databases, prescription event monitoring , electronic health records, patient registries and record linkage between health databases.
