ABSTRACT:
A method for preparing a pharmaceutical microdispersion exhibiting enhanced bioavailability, including the steps of providing a thermodynamically stable pharmaceutical composition comprising at least one lipophilic pharmaceutical agent incorporated in a physiologically acceptable liquid carrier, the liquid carrier comprising one or more lipophilic solvents such as fluorochemicals and preferably at least one nonfluorinated co-solvent, and combining the stable pharmaceutical composition with an amount of at least one miscible diluent sufficient to initiate phase separation of the lipophilic pharmaceutical agent from the pharmaceutical composition wherein a microdispersion of the pharmaceutical composition is formed. Also disclosed are microdisperse pharmaceutical compositions and kits for forming such compositions.
