Ingredient (API)?
Active Pharmaceutical Ingredient (API) is a substance or a mixture of substances intended to be used in the manufacture of a pharmaceutical dosage form, and that, when used in the production of a drug, becomes an active ingredient that produces a pharmacological effect in the body. APIs can be synthesized, extracted from natural sources, or produced by fermentation, and they are the key components of any pharmaceutical drug. They are often referred to as the "active ingredients" in a drug formulation because they are responsible for the therapeutic effects of the drug.
