  • Publication number: 20110256217
    Abstract: Delayed release oral pharmaceutical formulations and methods for enhanced intestinal drug absorption. The formulation comprises a first population of carrier particles comprising a drug and a penetration enhancer which are released at a first location in the intestine, and a second population of carrier particles comprising a penetration enhancer and a delayed release coating or matrix. This penetration enhancer is released at a second location in the intestine downstream from the first location and enhances absorption of the drug when it reaches the second location.
    Type: Application

  • Publication number: 20030083286
    Abstract: Compositions and methods for enhanced intestinal drug absorption. The formulation comprises a first population of carrier particles comprising a drug and a bioadhesive compound and a second population of carrier particles comprising a penetration enhancer. The bioadhesive extends the residence time of the drug and its absorptive potential across the portion of the intestinal mucosa made permeable by the penetration enhancer.
