This document is a project report submitted by Abhishek Saurabh for the degree of Bachelor of Pharmacy at Birla Institute of Technology in Ranchi, India in 2015. The report provides an overview of the historical development of pharmaceutical regulatory affairs in the United States, Europe, and India from the early 19th century to the present. It discusses key events that shaped drug regulation, such as the vaccine tragedy of 1901 in the US that led to the Biologics Control Act of 1902, and various tragedies in the 1950s that increased legislation around drug quality, safety and efficacy.
