PHARMACEUTICAL COMPOSITIONS RELEASING THEIR ACTIVE AGENTS FROM A BUCCAL OR SUBLINGUAL LOCATION TO OVERCOME AN ABSORPTION WINDOW PROBLEM

摘要

Disclosed are controlled release dosage forms of pharmaceutical or nutritional agents that are intended for retention in a buccal or sublingual location for administration. The dosage forms are particularly useful for the sustained release administration of drugs that have a limited window of absorption in the gastrointestinal tract and that are minimally, if at all, absorbed nucosally.
