Excipient. An excipient is generally a pharmacologically inactive substance formulated with the active ingredient of a medication. Excipients are commonly used to bulk up formulations that contain potent active ingredients, to allow convenient and accurate dispensation of a drug substance when producing a dosage form.
Excipients can also be useful in the manufacturing process, to aid in the handling of the active substance concerned such as by facilitating powder flowability or non-stick properties, in addition to aiding in vitro stability such as prevention of denaturation or aggregation over the expected shelf life.
