Pharmacovigilance in developing countries (part I): importance and challenges.

The thalidomide disaster was the significant historical event that acted as a catalyst for pharmacovigilance activity. Following this event developed countries initiated drug monitoring systems that evolved and now extend their scope to broader drug-related safety issues; however, this was not the case in developing countries. Pharmacovigilance is still a relatively new concept with low priority in developing countries although various issues are raising concerns that magnify the need for systems to monitor post marketing drug safety in these countries. This article analyzes the barriers to introducing robust pharmacovigilance systems in developing countries.
