What is the Origin of FDA Drug Approval Process?

The modern, systematic drug approval process originates primarily from the Federal Food, Drug, and Cosmetic Act of 1938, which was strengthened significantly by the Kefauver-Harris Amendments of 1962, mandating proof of efficacy in addition to safety. The FDA's role as the primary regulatory body stems from its mission to protect public health.

What is the Mechanism of FDA Drug Approval Process?

The mechanism commences with an Investigational New Drug (IND) application to begin human clinical trials, which proceed through Phase I (safety), Phase II (efficacy and dosing), and Phase III (large-scale efficacy and monitoring) studies. Upon successful completion, the sponsor submits an NDA containing all data for the FDA's thorough review of the drug's benefits versus risks. Only after the FDA concludes the data supports the drug's safety and effectiveness for the specified indication is the drug granted final marketing approval.

FDA Drug Approval Process

Meaning

The rigorous, multi-stage regulatory pathway mandated by the U.S. Food and Drug Administration (FDA) that a pharmaceutical company must successfully navigate before a new drug can be legally marketed and sold to the public. This extensive process is designed to ensure that all approved medications are both safe and effective for their intended use, based on comprehensive scientific evidence. The procedure involves pre-clinical research, clinical trials across multiple phases, and a final review of the New Drug Application (NDA).
