Active pharmaceutical ingredients can be described as the biologically active components in a drug product. They serve as the primary therapeutic agents that treat diseases and conditions. As such, the sourcing and supply of APIs are critically important, influencing both the quality of pharmaceutical products and their regulatory compliance. Suppliers of APIs must adhere to stringent regulations laid out by health authorities such as the U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA). These regulations ensure that APIs are produced in facilities that meet Good Manufacturing Practices (GMP), safeguarding the consistency and quality of the ingredients.
