Interactions between your drugs
vismodegib tucatinib
Applies to: Erivedge (vismodegib), tucatinib
MONITOR: Coadministration with inhibitors of CYP450 2C8 may increase the plasma concentrations of tucatinib, which is primarily metabolized by the isoenzyme. When gemfibrozil (600 mg twice daily), a potent CYP450 2C8 inhibitor, was administered with a single tucatinib dose of 300 mg, tucatinib peak plasma concentration (Cmax) and systemic exposure (AUC) increased by 1.6-fold and 3-fold, respectively.
MANAGEMENT: Increased monitoring is advised if tucatinib is coadministered with CYP450 2C8 inhibitors. Dosage adjustments may be required based on clinical response and tolerance.
