Pharmacovigilance (or drug safety surveillance) is a branch of science which deals with adverse reactions of pharmaceutical products enclosing collection, detection, monitoring, assessment and prevention of adverse reaction of pharmaceutical products. It is one of the crucial steps in drug development process, which ensures safety of newly developed pharmaceutical product.
