Abstract: This invention is concerned with an oral sustained release pharmaceutical preparation which is prepared as a pharmaceutical preparation comprising lower alkyl ether of cellulose, polyacrylic acid or its pharmaceutically acceptable salt, and active drugs, or a pharmaceutical preparation comprising lower alkyl ether of cellulose, polyacrylic acid or its pharmaceutically acceptable salt, and active drugs together with a foaming agent, so that it may release the active drugs by such slow degrees in the stomach or the intestinal tract as to make it possible to provide an adequate supply of active drugs in enough concentration to display their therapeutic value for many hours.

Abstract: A method for administering a medicament which comprises adhering to the mucosa of the oral or nasal cavity a pharmaceutical preparation comprising(a) a water-swellable and mucosa-adhesive polymeric matrix comprising about 50 to about 95% by weight of a cellulose ether and about 50 to about 5% by weight of a homo- or copolymer of acrylic acid or a pharmaceutically acceptable salt thereof, and(b) dispersed therein, a pharmaceutically effective amount of the medicament,said preparation releasing continuously the medicament at a controlled rate; and causing the released medicament to be absorbed through the mucosa or enterally; said mucosa-adhesive preparation; and process for said preparation.
