Document Type and Number:
WIPO Patent Application WO/2003/013471
Kind Code:
A2
Abstract:
An enteric coated pharmaceutical composition containing chitosan is protected from the acidic stomach environment and exposed in the alkaline environment of the small intestine where it can bind fat. An activator, typically a pharmaceutically acceptable acid, is included in the composition to create an acidic micro-environment in the alkaline medium of the small intestine to increase the solubility of the chitosan and hence its ability to bind fat.
