NCIt definition : A synthetic formulation in which the antineoplastic agent cisplatin is encapsulated
in lipids. Cisplatin liposomal consists of small aggregates of cisplatin covered by
a single lipid bilayer. Encasement in liposomes improves cisplatin's tumor bioavailability
and toxicity profile. Liposomal encapsulation does not affect the pharmacological
properties of cisplatin directly. Cisplatin forms highly reactive, charged, platinum
complexes which bind to nucleophilic groups such as GC-rich sites in DNA, inducing
intrastrand and interstrand DNA cross-links, as well as DNA-protein cross-links. These
cross-links result in apoptosis and cell growth inhibition. (NCI04);
