The role of competition in determining the prices of generic drugs in Brazil

Abstract

The objective of this article is to analyze the role of competition in selected relevant markets (RM) and its influence on the price differential between generic and reference medicines. This is a case study of 268 commercial presentations of drugs, classified as RM in 2001 and 2016. The data to obtain the degree of concentration came from the database used by Hasenclever (2002) and the 2016 Statistical Yearbook of the Pharmaceutical Market. The prices in 2019 were taken from 10 pharmacy and drugstore websites. The results indicate that the 35% margin on the price of the reference drug imposed at the factory price for the entry of the generic on the market is low compared with the differential average retail prices. Furthermore, it was noted that the greater the number of suppliers, the greater tended to be the price differential between generics and reference medicines.
