Use of peg-derivatized lipids as surface stabilizers for nanoparticulate compositions

摘要

Nanoparticulate compositions comprising an insoluble organic drug and at least one polyethylene glycol-derivatized lipid adsorbed on the surface of the drug are described. The polyethylene glycol-derivatized lipid can be a PEG-phospholipid, PEG-cholesterol, PEG-cholesterol derivative, PEG-vitamin A, PEG-vitamin E, or a mixture thereof The compositions have an effective average particle size of less than about 1 micron. The invention also describes methods of making and using such compositions.
