Patent

CA 2142653

A novel delivery system for targeting drugs to the colon is comprised of three parts: (1) an enteric coating to prevent penetration of gastric fluid into the delivery system, thereby preventing any drug release in the stomach; (2) an erodible polymer layer which is exposed and gradually erodes during transit through the upper intestinal tract, and (3) a core, which is a conventional tablet or beadlet containing an active ingredient(s), which readily disintegrates and subsequently releases the drug to the target site, the colon, after erosion of the erodible polymer layer.
