This invention relates to an oramucosal pharmaceutical dosage form in the form of a wafer. The wafer comprises a porous, hydroscopic, muco-adhesive polymeric matrix with at least one desired pharmaceutically active compound added thereto. The polymer is selected from a number of polymers having different dissolution rates and, in use when taken orally, the matrix adheres to an oramucosal surface to dissolve over a predetermined period of time to release the pharmaceutically active compound. The invention also extends to a method of manufacturing an oramucosal pharmaceutical dosage form in the form of a wafer which involves freeze drying or lyophilisation.
