ABSTRACT:
Compositions comprising microaggregates containing hydrophobic drugs, as well as methods for their production, are described. Such microaggregates may include micelle structures or combinations thereof with liposomes, and constitute an effective delivery vehicle for a hydrophobic agent. Methods for microaggregate production include the use of preferred lipid compounds and processing conditions favoring the production of small aggregates for improved filter sterilization.
