Active pharmaceutical ingredient
An Active Pharmaceutical Ingredient, or API, is the substance in drug that is pharmaceutically active .
A capsule, tablet, syrup, intravenous fluid, or any other formulation of a drug is traditionally composed of two things: The API, which is the drug itself; and an excipient, which is the substance of the tablet, or the liquid the API is suspended in, or other material that is pharmaceutically inert.
