Active Moiety

Active Moiety

The molecule or ion which is responsible for the physiological or pharmacological action of the drug or chemical substance. Active moiety does not refer to the appended portions of the molecule which define it as an ester, salt, including a salt with hydrogen or coordination bonds, or other noncovalent derivative—e.g., a complex, chelate, or clathrate—of the molecule.

The FDA defines bioequivalence as "the absence of a significant difference in the rate and extent to which the active ingredient or active moiety in pharmaceutical equivalents or pharmaceutical alternatives becomes available at the site of drug action when administered at the same molar dose under similar conditions in an appropriately designed study." In statistical terms, this translates into allowing a generic to vary from 80% to 125% of the original drug.
