The article enables release of a drug at a constant plateau level, followed by a pulse of drug after a predetermined time, thus making the composition of the invention especially suitable for use in, e.g., treatment of rheumatoid arthritis or related disorders with non-steroidal anti-inflammatory agents. | InventorsAssigneeApplicationNo. 505924 filed on 04/06/1990US Classes:424/473, With porous, perforated, apertured, or sieved layer (e.g., dialyzing layer, microporous layer, etc.)424/485, Natural gums, resin or latex424/488Polysaccharides (e.g., cellulose, etc.)Field of Search424/485, Natural gums, resin or latex424/488, Polysaccharides (e.g., cellulose, etc.)424/473With porous, perforated, apertured, or sieved layer (e.g., dialyzing layer, microporous layer, etc.)ExaminersPrimary: Page, Thurman K.Assistant: Phelan, D.
