Abstract:
Submicron particles of an organic compound, such as therapeutic and diagnostic agent are disclosed. The organic compound particles are associated with a least two surfactants including a block copolymer and phospholipids conjugated with a hydrophilic polymer.
Abstract:
The present invention is concerned with the formation of small particles of an organic compound by mixing a solution of the organic compound dissolved in a water-miscible organic solvent with an aqueous medium to form a mix and simultantously homogenizing the mix while continuously removing the organic solvent to form an aqueous suspension of small particles essentially free of the organic solvent. These processes are preferably used to prepare an aqueous suspension of small particles of a poorly water-soluble, pharmaceutically active compound suitable for in vivo delivery by an administrative route such as parenteral, oral pulmonary, nasal, buccal, topical, ophthalmic, rectal, vaginal, transdermal or the like.

Abstract:
The present invention is concerned with the formation of submicron particles of an antineoplastic agent, particularly paclitaxel, by precipitating the antineoplastic agent in an aqueous medium to form a pre-suspension followed by homogenization. Surfactants with phospholipids conjugated with a water soluble or hydrophilic polymer such as PEG are used as coating for the particles. The particles produced generally have an average particle size of less than about 1000 nm and are not rapidly soluble.
