Delivery system with increased bioavailability

摘要

The present invention is directed to a dry composition which allows delivery of active agents with good bioavailability. These compositions are prepared by emulsifying the active agent using liposome technology known in the art and then encapsulating with a modified starch. The modified starch is prepared by enzymatic hydrolysis of starch after the preparation of a starch derivative containing a hydrophobic group or both a hydrophobic and a hydrophilic group. The resultant composition is a dry powder with excellent bioavailability. Further, the composition has good load levels and stability.
