Contraindication of Votrient 400
Severe hepatic (total bilirubin >3 times ULN) impairment and Lactation by Continue use with strong P-glycoprotein (P-gp) or breast cancer resistance protein (BCRP) inducers and inhibitors and strong CYP3A4 enzyme inducers.
Drug Interaction of Votrient 400
Votrient 400MG with strong CYP3A4 enzyme inhibitors (e.g. ketoconazole, itraconazole, voriconazole, clarithromycin, telithromycin, atazanavir, indinavir, ritonavir, sqauinavir, nefazodone, lapatinib)will Increase plasma concentration. Votrient increases incidence of ALT elevation with simvastatin. Votrient 200mg with PPI e.g. esomeprazole decreases bioavailability.
Votrient with Concomitant use of strong of P-gp or BCRP inhibitors (e.g. lapatinib) and inducers may alter the exposure and distribution of pazopanib. Votrient 200mg with rifampin(strong CYP3A4 Enzyme inducers) will decreases the plasma concentration.
