Drug safety surveillance and assessment

Drug Safety Surveillance and Assessment

Drug safety surveillance and assessment are critical components of pharmacovigilance, which is the science and activities related to the detection, assessment, understanding, and prevention of adverse effects or any other drug-related problems. Pharmacovigilance ensures that patients receive safe and effective medications by monitoring and evaluating the safety of drugs throughout their lifecycle, from pre-clinical development to post-marketing surveillance.
