Post-Marketing Surveillance

Meaning

Post-Marketing Surveillance (PMS) is the continuous, systematic, and mandatory process of monitoring the safety and long-term efficacy of a pharmaceutical product, medical device, or regulated therapeutic intervention after it has successfully been released for public use. This clinical and regulatory requirement is absolutely crucial for the timely detection of rare, delayed, or long-term adverse effects that may not have been statistically apparent during the limited scope and duration of pre-market clinical trials. It represents an essential component of responsible clinical practice, ensuring ongoing safety data collection for maximum patient well-being.
