The Food, Drug, and Cosmetic Act (FDCA) is a pivotal piece of legislation enacted in 1938 that gives the Food and Drug Administration (FDA) the authority to oversee the safety of food, drugs, and cosmetics. This law established a framework for regulating these products, ensuring they are safe for consumption and use. It is crucial in defining the FDA’s regulatory process, particularly regarding medical devices and their classification, as it sets forth guidelines that manufacturers must follow to obtain approval for their products.
