Methods and dosage forms for improving the bioavailability of therapeutic agents

摘要

The present invention relates to methods and dosage forms for improving the bioavailability of therapeutic agents that are metabolized in the upper gastrointestinal (GI) tract. The present invention improves the bioavailability of by administering such therapeutic agents in a floating dosage form. The floating dosage forms are kept in the stomach for extended periods of time and the therapeutic agents are not immediately released after ingestion. Controlled release of such therapeutic agents from the dosage forms prevents enzyme saturation thereby improving the bioavailability of such therapeutic agents.
