What is the Origin of Postmarket Surveillance?

This is a regulatory and public health term combining Postmarket, meaning after the product has entered the commercial marketplace, and Surveillance, meaning continuous, close observation. The concept arose from the need for real-world data collection to complement the controlled environment of clinical trials. It is a critical component of a comprehensive product lifecycle management system.

What is the Mechanism of Postmarket Surveillance?

The process involves collecting and analyzing data from various sources, including spontaneous adverse event reporting systems, patient registries, and large-scale observational studies. Regulatory bodies utilize this information to identify safety signals, assess risk-benefit profiles in diverse populations, and, when necessary, implement regulatory actions. These actions may include updating product labeling, issuing safety warnings, or, in rare cases, withdrawing the product from the market to protect public health.

Postmarket Surveillance

Meaning

Postmarket Surveillance is a systematic, ongoing process of monitoring the safety and efficacy of a pharmaceutical drug, medical device, or biologic product after it has been approved by regulatory agencies and released for commercial use by the general public. This phase of monitoring is crucial for detecting rare, long-term, or previously unknown adverse effects that may not have been observed during pre-market clinical trials. It represents a vital public health and regulatory function.
