VOTRIENT tablets are for oral use. Each 200-mg tablet of VOTRIENT contains 200 mg of pazopanib equivalent to 216.7 mg of pazopanib hydrochloride. The inactive ingredients of VOTRIENT are: Tablet Core: magnesium stearate, microcrystalline cellulose, povidone, and sodium starch glycolate. Coating: Gray or pink film-coat: hypromellose, iron oxide black, macrogol/polyethylene glycol 400 (PEG 400), polysorbate 80, and titanium dioxide.
Mechanism of Action
Pazopanib is a multi-tyrosine kinase inhibitor of vascular endothelial growth factor receptor (VEGFR)-1, VEGFR-2, VEGFR-3, platelet-derived growth factor receptor (PDGFR)-α and -β, fibroblast growth factor receptor (FGFR)-1 and -3, cytokine receptor (Kit), interleukin-2 receptor-inducible T-cell kinase (Itk), lymphocyte-specific protein tyrosine kinase (Lck), and transmembrane glycoprotein receptor tyrosine kinase (c-Fms). In vitro, pazopanib inhibited ligand-induced autophosphorylation of VEGFR-2, Kit, and PDGFR-β receptors. In vivo, pazopanib inhibited VEGF-induced VEGFR-2 phosphorylation in mouse lungs, angiogenesis in a mouse model, and the growth of some human tumor xenografts in mice.
