A cationic liposome preparation of paclitaxel with antineoplastic activity. Paclitaxel, the active ingredient in cationic liposome-encapsulated paclitaxel, binds to tubulin and inhibits the disassembly of microtubules, resulting in the inhibition of mitosis and cellular proliferation, and apoptosis. Cationic liposome encapsulation of paclitaxel allows the delivery of high doses of paclitaxel to target tissues while minimizing systemic toxicity. Tumor endothelial cells may preferentialy bind and internalize cationic liposomes. Check for active clinical trials using this agent. (NCI Thesaurus)
