    摘要: The present invention is directed to liposomal compositions comprising a camptothecin, which are optimized to reduce camptothecin degradation and/or precipitation of camptothecin degradation products in the external medium. The invention further provides improved methods of formulating liposomal camptothecins, kits comprising liposome-encapsulated camptothecins, and methods of using the same to treat a variety of diseases and disorders, including cancer.

    摘要: Methods for encapsulating ionizable antineoplastic agents in liposomes using transmembrane potentials are provided. Trapping efficiencies approaching 100% and rapid loading are readily achieved. Dehydration protocols which allow liposomes to be conveniently used in the administration of antineoplastic agents in a clinical setting are also provided. In accordance with other aspects of the invention, transmembrane potentials are used to reduce the rate of release of ionizable drugs from liposomes.
