Abstract: Modified release pharmaceutical composition and method for the treatment of inflammatory bowel diseases (IBD) such as Crohn's disease and Colitis Ulccrosa, said compositions comprising as active the ingredient 5-aminosalicylic acid (5-ASA), and being adapted for modified and targeted release so as to obtain a clinically important localized effect profile of 5-ASA by means of releasing an appropriate amount of 5-ASA in both the small and large bowel.

Abstract: Compositions for use in the regulation of subnormal pH values in intestinal tract and for treatment of bowel diseases. The compositions comprise a coating and a substantially insoluble alkaline material confined within said coating, the composition being adapted so as to ensure the availability of an amount of said pH regulating alkaline material in the lumen of the gastrointestinal tract exhibiting subnormal pH values. E.g. In the proximal small intestine, the mid small intestine, the distal small intestine, the caecum, the ascending colon, the transverse colon, the descending colon, the sigmoid colon and/or the rectum. The compositions may also comprise a medicament for treatment of bowel disease, e.g. 5-aminosalicylic acid for the treatment of Crohn's disease and colitis ulcerosa. The administration may be oral composition or enemas or suppositories.

Abstract: Suppositories, produced by a process in which a suppository basic mass is produced containing (a) 50-75% of 5-aminosalicylic acid as an active ingredient, (b) 2-5% talc, magnesium stearate and/or polyvinyl pyrrolidone and (c) 20-48% by weight of a polyethylene glycol having an average molecular weight of at least 4000, and the produced mass is compressed to suppositories in a tabletting machine.
