receptor (VEGFR)-1, VEGFR-2, VEGFR-3, platelet-derived growth factor receptor (PDGFR)-á and -a, fibroblast growth factor receptor (FGFR) -1 and -3, cytokine receptor (Kit), interleukin-2 receptor inducible T-cell kinase (Itk), leukocyte-specific protein tyrosine kinase (Lck), and transmembrane glycoprotein receptor tyrosine kinase
Pharmacokinetics
Absorption: Pazopanib is absorbed orally with median time to achieve peak
concentrations of 2 to 4 hours after the dose. Daily dosing at 800 mg results
in geometric mean
Pregnancy and lactation:
USE IN SPECIFIC POPULATIONS
1 Pregnancy
Pregnancy Category D
VOTRIENT can cause fetal harm when administered to a pregnant woman.

are excreted in human milk and because of the potential for serious adverse
reactions in nursing infants from VOTRIENT,a decision should be made whether
to discontinue nursing or to discontinue the drug, taking into account the
importance of the drug to the mother
3 Pediatric Use
The safety and effectiveness of VOTRIENT in pediatric patients have not been
established.
4 Geriatric Use
In clinical trials with VOTRIENT for the treatment of RCC,
196 subjects (33%) were aged 65 years, and 34 subjects (6%) were
