Talk:Postmarketing surveillance

Is Pharmacovigillance equal to Post Marketing Surveillance?
If they are same, why not to redirect one article to other? And if they are different, what is the exact difference? I have also asked this question at the talk page of article of Pharmacovigillance. Thanks in advance. --Abhijeet Safai (talk) 13:44, 1 April 2015 (UTC)
 * After reading the article in detail, I am able to understand the PMS is a part of PV. Is PMS a subgroup of PV? Is it that, that when it is done by company, it is known as PMS and when done by government, it is known as PV? Is PMS targeted at less population and is PV targeted at larger population? Thanks. --Abhijeet Safai (talk) 13:47, 1 April 2015 (UTC)

Prevalence studies
Is there any studies on how often approved medices are withdrawn from market due to postmarketing surveillance or pharmacovigilance? --Custoo (talk) 12:11, 5 November 2017 (UTC)
