Abstract
A pharmaceutical composition is provided which comprises an aqueous suspension of solid particles, the solid particles comprising a camptothecin, the solid particles having mean diameters between about 0.05 um and 10 um, the particles coated with a 0.3 nm to 3.0 um thick layer of a membrane-forming amphipathic lipid. The pharmaceutical composition is particularly well suited for delivering camptothecins, particularly 9-nitro-camptothecin intravenously.
