Post-Marketing Studies

Frequently, pharmaceutical companies carry out post-marketing studies (PMS) following market approval of medicinal products and devices. These observational studies are intended to provide scientific insight into the long-term safety, application and interaction of drugs in everyday medical practice. Government regulators use PMS to monitor drug safety and especially to detect rare and very rare side effects. This important task of PMS is legally defined and standardized within the European Union. There is little known about the content and methodological aspects of PMS. The project investigates the practice of PMS to assess its scientific value.
