The FDA stands for the Food and Drug Administration. It is a federal agency of the United States Department of Health and Human Services, responsible for regulating and supervising food safety, pharmaceuticals, medical devices, cosmetics, and other products related to public health.

The FDA was established in 1906 with the passage of the Pure Food and Drugs Act, which was enacted to ensure the safety and quality of food and drugs sold in the United States. The agency is responsible for enforcing regulations and guidelines related to the development, testing, and distribution of products related to public health.

The FDA's main goals are to protect public health, ensure the safety and effectiveness of products regulated by the agency, and promote innovation and development in the industry. The FDA achieves these goals through a combination of regulatory oversight, scientific research, and public education.

The FDA is a significant player in the global pharmaceutical industry, and its regulations and guidelines are followed by many other countries. Its role is critical in ensuring that products consumed by the American public are safe, effective, and of high quality.
