Brazil x United States: A Comparison of Post-Marketing Pharmacovigilance Requirements (RDCs x FDA)

Anvisa

Post-marketing pharmacovigilance is a critical component of medicines regulation in both Brazil and the United States. While both countries share the common goal of protecting public health, their regulatory frameworks differ in reporting timelines, safety reporting systems, and approaches to risk minimization.

This Blog provides a comparative analysis of Brazilian requirements—primarily established under RDC No. 406/2020 and RDC No. 967/2025—and the U.S. pharmacovigilance model overseen by the Food and Drug Administration (FDA), with a focus on reporting timelines, VigiMed x FAERS, and risk management strategies.

Brazil’s Pharmacovigilance Framework: From RDC 406/2020 to RDC 967/2025

Brazil has undergone a significant regulatory evolution in pharmacovigilance over the past few years. With the publication of RDC No. 406/2020, the country established a consolidated framework for Good Pharmacovigilance Practices applicable to Marketing Authorization Holders (MAHs). In 2025, this framework was further strengthened by RDC No. 967/2025, reinforcing governance, risk-based oversight, and international harmonization.

The National Health Regulatory Agency (ANVISA) has published a new set of guidelines regarding the classification, identification, and control of impurities and degradation products in medicines. This update is crucial for the pharmaceutical industry as it establishes clearer and more rigorous criteria for demonstrating product safety and quality. The focus of the new guidelines is to harmonize national practices with international guidelines and ensure that acceptable limits for these substances are consistently monitored throughout the drug’s lifecycle, from production to expiration date.

Navigating the Frontier: The Global Regulatory Landscape for AI/ML-Enabled Medical Devices

Navigating the Frontier

The incorporation of Artificial Intelligence and Machine Learning (AI/ML) into medical devices has the potential to revolutionize diagnosis, treatment, and health management. However, the adaptive and constantly evolving nature of these algorithms challenges traditional regulatory frameworks. This article provides an overview of the complex and dynamic global regulatory landscape—with a focus on leading agencies like the FDA (USA) and the European Union (EU)—highlighting the main challenges and the innovative approaches being developed to ensure the safety and effectiveness of these “learning” devices.

Towards Sanitary Sovereignty: The Infliximab API and the Challenge of National Production

Anvisa

The recent authorization by Anvisa (Brazil’s Health Regulatory Agency) for the national production of the Active Pharmaceutical Ingredient (API) of infliximab by Bionovis marks a strategic step for the health and national security of Brazil. The biopharmaceutical, essential for treating autoimmune diseases, symbolizes the effort to reverse the critical dependence on imported inputs, which currently accounts for about 95% of the total. This article explores the historical importance of this recovery, the structural and professional capacity challenges involved, and the crucial role of policies such as the Productive Development Partnerships (PDPs) for the rebirth of the Health Economic-Industrial Complex (CEIS).
