What is pazopanib?

Pazopanib is a type of medicine called a targeted therapy. This medicine is a tyrosine kinase inhibitor or vascular endothelial growth factor (VEGF) inhibitor. It acts to block certain cell signals to help keep cells from growing. It can also help block the growth of blood vessels that supply oxygen to tumors.

Patients will have regular blood draws to check blood counts and electrolyte levels in the blood and monitor liver and kidney function. Blood pressure and heart function may also be monitored. The dose of pazopanib may change based on results of lab tests.
