STABLE TABLET DOSAGE FORMS OF PROTON PUMP INHIBITORS

摘要

This invention relates to a method of making oral formulations of practically water insoluble, or very slightly water soluble proton pump inhibitors, the oral dosage forms so made, and methods of use thereof. The oral dosage form has a core tablet of compressed particles composed of powder particles of a pharmaceutically acceptable material, having coated thereon admixture of an amorphous, salt form of a benzimidazole proton pump inhibitor produced in-situ; and a pharmaceutically acceptable, water-soluble, hydrophilic polymer having a surfactant functionality. The coated core tablet has a pharmaceutically acceptable sub-coating on the core tablet; and a pharmaceutically acceptable enteric coating on the sub-coating. The coated tablet may provide enhanced absorption when administered orally.
