[Precautions] 1) Elevated serum transaminase and bilirubin levels have been observed. Severe and fatal hepatotoxicity has occurred. Liver chemistries should be monitored prior to initiating treatment and periodically during treatment. 2) QT interval prolongation and *torsades de pointes* have been observed. Use with caution in patients at higher risk for QT interval prolongation. ECG and electrolyte monitoring should be considered. 3) Fatal hemorrhagic events have been reported. VOTRIENT has not been studied in patients with a history of hemoptysis, cerebral hemorrhage, or clinically significant gastrointestinal bleeding within the past 6 months; therefore, it should not be used in these patients. 4) Arterial thrombotic events, some of which were fatal, have been observed. Use with caution in patients at increased risk for these events. 5) Gastrointestinal perforation or fistula formation has occurred. Fatal perforation events have occurred. Use with caution in patients at increased risk for gastrointestinal perforation or fistula formation. 6) Hypertension has been observed. Blood pressure should be well-controlled prior to initiating VOTRIENT. Monitor and treat hypertension as needed. 7) Discontinuation of VOTRIENT treatment is recommended in patients undergoing surgery. 8) Hypothyroidism may occur. Monitoring of thyroid function is recommended. 9) Proteinuria: Monitor for urinary protein. Discontinue the drug in cases of Grade 4 proteinuria. 10) VOTRIENT may cause fetal harm when administered to pregnant women. Women of childbearing potential should be advised of the potential hazard to the fetus and to avoid pregnancy while taking the medication. Please read the package insert carefully and use strictly according to physician's instructions.

[Drug Interactions] Pazopanib is a tyrosine kinase inhibitor of VEGFR; it acts by selectively inhibiting VEGFR-1, VEGFR-2, and VEGFR-3, competitively binding with ATP at the intracellular ligand-binding sites, thereby blocking intramolecular tyrosine autophosphorylation, inhibiting VEGFR activation, and consequently accelerating apoptosis, inhibiting angiogenesis, and suppressing tumor infiltration and metastasis. In in vitro studies, pazopanib effectively inhibited vascular endothelial growth factor (VEGF)-induced VEGFR phosphorylation and angiogenesis in mouse lungs. Additionally, pazopanib specifically targets platelet-derived growth factor receptors (PDGFR)-α and PDGFR-β, fibroblast growth factor receptors (FGFR)-1 and -3, stem cell factor receptor (Kit), inducible T-cell kinase (Itk), leukocyte-specific protein tyrosine kinase (Lck), and transmembrane glycoprotein receptor tyrosine kinase (c-Fms).
