Regulatory approval is the official authorization granted by a government agency—such as the FDA, EMA, or other health authority—allowing a medical product to be marketed or used in a specific region. This decision is based on a comprehensive review of clinical, nonclinical, and manufacturing data to ensure the product meets established standards for safety, efficacy, and quality. Securing regulatory approval is a critical milestone in the drug and device development process, marking the transition from research to real-world use.
