ABSTRACT:
This invention relates to proliposomal drug-delivery systems for medicaments. In particular, it relates to enteric-coated proliposomal formulations for poorly water soluble drugs and methods for making the same. The drug delivery system comprises a pharmaceutical agent, a phospholipid and a coating material. The present invention provides enhanced stability and bioavailability for pharmaceutical formulations.
