NCI Drug Dictionary


injectable liposomal vinorelbine 
An injectable, sphingomyelin/cholesterol liposome-encapsulated formulation of the semisynthetic vinca alkaloid vinorelbine with antineoplastic activity. Vinorelbine binds to tubulin and prevents formation of the mitotic spindle, resulting in cell cycle arrest in metaphase. Like other vinca alkaloids, vinorelbine may also interfere with the metabolism of nucleic acids, lipids, amino acids, cAMP, and glutathione, as well as other biological processes including calmodulin-dependent Ca2+-transport, ATPase activity, or cellular respiration. Liposomal delivery of vinorelbine may improve drug penetration into tumors and decreases drug clearance, increasing the duration of therapeutic effects while lowering the toxicity profile. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
