Overview of Brazilian Requirements for Therapeutic Equivalence of Orally Inhaled and Nasal Drug Products


Brazil has established a framework for provision of generic pharmaceuticals including for orally inhaled and nasal drug products (OINDP) to its populace. This includes the development of guidelines or “resolutions” and normative instructions describing the Brazilian medicines agency’s (Anvisa) expectations for demonstrating OINDP therapeutic equivalence. The Anvisa regulatory framework for OINDP therapeutic equivalence, challenges, and comparisons with the US Food and Drug Administration and European Medicines Agency approaches are assessed and discussed.

A Normative Instruction provides details associated with Resolution requirements such as testing procedures, acceptance criteria, etc, and is also subject to public consultation.
