A drug API is the primary ingredient that produces the intended pharmacological effect in a drug formulation. It can be derived from natural sources, such as plants or animals, or synthesized through chemical processes. The quality, purity, and consistency of the API are critical, as impurities or variations can lead to ineffective treatments or adverse side effects. Drug APIs undergo rigorous testing and must comply with stringent regulatory standards established by agencies such as the U.S. Food and Drug Administration (FDA) or the European Medicines Agency (EMA).
