NCIt definition : A formulation of the poorly soluble, semi-synthetic, second-generation taxane docetaxel
encapsulated within liposomes, with antineoplastic activity. Upon intravenous administration,
docetaxel binds to and stabilizes tubulin, thereby inhibiting microtubule disassembly
which results in cell-cycle arrest at the G2/M phase and cell death. This liposomal
formulation solubilizes docetaxel without the use of toxic solvents such as Tween
80, permitting the administration of larger doses of docetaxel while avoiding solvent-associated
toxicity, including hypersensitivity reactions. In addition, liposomal delivery of
docetaxel improves drug penetration into tumors and decreases drug clearance, thereby
increasing the duration of therapeutic drug effects while lowering the toxicity profile.;
