Abstract:
The present invention provides compositions and methods for the multiple release of a drug in the gastrointestinal tract of a subject through the use of an oral multiple drug release system. The system provides site-specific release of the drug to both the small intestine and the colon in the form of multiple controlled doses for long-lasting efficacy, thereby reducing the drug dosing frequency.
