Though excipients were at one time assumed to be "inactive" ingredients, it is now understood that they can sometimes be a key determinant of dosage form performance.

FDA regulations and standards require that all ingredients in drugs, as well as their chemical decomposition products, be identified and shown to be safe.

Often, more excipient is found in a final drug formulation than active ingredient, and practically all marketed drugs contain excipients.

As with new drug substances and dosage forms thereof, novel excipients themselves can be patented; sometimes, however, a particular formulation involving them is kept as a trade secret instead (if not easily reverse-engineered).
