A drug delivery vehicle comprising a pharmaceutical carrier particle bearing microparticles of a drug deposited on the pharmaceutical carrier particle from a solid solution of the drug in a sublimable carrier.
A method of making a drug delivery vehicle comprising the steps of:
- a) forming a solid solution of the drug and a sublimable carrier on the surface of a pharmaceutical carrier particle, and
- b) subliming the sublimable carrier from the solid solution to deposit microparticles of the drug on the surface of the pharmaceutical carrier particle to obtain the drug delivery vehicle.
A pharmaceutical composition comprising a plurality of microparticles of a drug and at least one pharmaceutically acceptable excipient, wherein the microparticles are formed by removing sublimable carrier from a solid solution of the drug in the sublimable carrier.
