Pharmacovigilance is the science and practice related to detection, analysis, understanding and avoidance of adverse reactions or any other problems connected with the use of drugs.
Pharmacovigilance studies adverse reactions, which are caused not only by pharmacological properties of a drug, but are also triggered by a number of other factors:
- medical errors;
- failure to use drugs based on indications;
- cases of acute and chronic intoxication;
- excessive use;
- various types of interactions.
