__Abstract__
As defined by World Health Organization (WHO), pharmacovigilance is the
science and activities relating to the detection, assessment, understanding and
prevention of adverse effects or any other drug-related problem (adverse drug
reactions, ADRs). The aims of pharmacovigilance are to improve patient care
and patient safety in relation to the use of medicines and to support public health
programmes by providing reliable, balanced information on the risk-benefit profile
of medicines
