Evaluation of the effects of a generic substitution policy implemented in Chile.

Introduction: Chile implemented a generic substitution policy in 2014 to improve access to medicines. This study aims to measure if the generic substitution policy had an effect on the sales volume and prices of referent and the branded generic products with demonstrated bioequivalence (BEQ) in the private pharmaceutical market.
