It involves the collection, detection, assessment, monitoring, and prevention of adverse events or any other drug-related problems. Pharmacovigilance aims to ensure that medicines are used safely by identifying and evaluating risks associated with medications throughout their lifecycle, from development to post-marketing. This field plays a crucial role in ensuring patient safety and promoting public health by identifying and managing risks associated with pharmaceutical products.
