Regulatory Information and Guidance for Drugs and Drug-Device Combinations

Medicinal products for delivery via respiratory tract (orally inhaled or intranasal drug products) typically combine the medicinal formulation (“drug”) and a delivery system (“device”).  Depending on their configuration and primary mode of action, they are regulated as drugs, or as devices, or as drug-device combination products.   

Regulatory agencies around the world have been actively supporting efforts to curb and combat the SARS-CoV-2 pandemic, and to adjust their other activities accordingly.

Medical Devices - Regulatory Information and Guidance

The regulation of medical devices is complex and often jurisdiction-specific. To help you better navigate this uncertainty, we have compiled the following list of resources of regulatory guidance and requirements by country. 

Brazil - Medical Devices

  • In response to the COVID-19 pandemic, Anvisa defined temporary criteria and procedures for certification of Good Manufacturing Practices for registration and post-registration changes of medicines, supplies, and health products. “Coronavirus: alternatives to GMP certification(March 13, 2020, Updated: March 18, 2020)

History of FDA regulation of medical devices 1976-2020

The Association for the Advancement of Medical Instrumentation® (AAMI) publishes resources to assist developers and manufacturers of ventilators and other medical equipment.

The US Food and Drug Administration’s Center for Devices and Radiological Health (FDA CDRH) is responsible for regulation of medical devices in the United States. CDRH publishes guidance documents for industry as well as information and resources for healthcare providers and general public. CDRH maintains a free public catalogue of regulatory tools for evaluation of medical devices.  Additionally, FDA CDRH maintains a webpage specifically dedicated to COVID-19 diagnostic tests, ventilators, and personal protective equipment (PPE).

Agencies of different countries do cooperate where appropriate.  See, for example:
