Microemulsions as solid dosage forms for oral administration

摘要

A microemulsion composition in the form of a free-flowing, compressible powder, comprises an admixture of a drug-containing oil-in-water microemulsion and a solid particle adsorbent. The drug-containing oil-in-water microemulsion comprises a oil-soluble drug, and the drug-containing microemulsion is adsorbed onto the solid particle adsorbent and forms a free-flowing, compressible powder. The composition and dosage forms of the present invention improve the bioavailability of a wide range of drugs that are known are suspected of having poor bioavailability by the utilization of several different mechanisms.
