Pharmaceutical composition containing bile acid sequestrant enclosed in a size-exclusion membrane

摘要

A pharmaceutical composition useful for treating hypercholesterolemia comprising a bile acid sequestrant resin such as cholestyramine and cholestipol maintained in a semipermeable water-insoluble material; wherein said semipermeable material enables bile acids from the digest tract to contact and bind to said resin while preventing substances having a higher molecular weight than bile acids from contacting said resin material. A method for treating hypercholesterolemia using the inventive composition is also disclosed.
