Microemulsions as solid dosage forms for oral administration

A microemulsion composition in the form of a free-flowing, compressible powder, comprising:

• an admixture of a drug-containing self-microemulsifying drug delivery system and a solid particle adsorbent;
• wherein said drug-containing self-microemulsifying drug delivery system is adsorbed on said solid particle adsorbent and forms a free-flowing, compressible powder.

A solid dosage for the oral administration of a therapeutically effective amount of a drug, comprising:

• an admixture of a drug-containing microemulsion and a solid particle adsorbent;
• wherein said microemulsion is adsorbed on said solid particle adsorbent and forms a free-flowing, compressible powder.

A method for preparing a microemulsion, comprising the steps of:

• preparing a drug-containing microemulsion;
• converting said drug-containing microemulsion into a free-flowing, compressible powder by admixing said drug-containing microemulsion with a solid particle adsorbent.

A method for preparing a solid dosage for the oral administration of a therapeutically effective amount of a drug, comprising the steps of:

• preparing a drug-containing microemulsion;
• converting said drug-containing microemulsion into a free flowing compressible powder by admixing said drug-containing microemulsion with a solid particle adsorbent;
• compressing said free-flowing, compressible powder into a solid dosage form.

A stable microemulsion composition which is the product of the process of:

• preparing a drug-containing microemulsion;
• converting said drug-containing microemulsion into a free-flowing, compressible powder by admixing said drug-containing microemulsion with a solid particulate adsorbent.

A method for delivering a drug to a mammal comprising the steps of:

• preparing a drug-containing microemulsion;
• converting said drug-containing microemulsion into a free-flowing, compressible powder by admixing said drug-containing microemulsion with a solid particle adsorbent;
• orally administering said free, flowing compressible powder to a mammal.
