Interactions between your drugs
telithromycin vorapaxar
Applies to: telithromycin, vorapaxar
GENERALLY AVOID: Coadministration with potent inhibitors of CYP450 3A4 may significantly increase the plasma concentrations of vorapaxar, which is a substrate of the isoenzyme. When vorapaxar was coadministered with ketoconazole 400 mg, mean vorapaxar peak plasma concentration (Cmax) and systemic exposure (AUC) increased by nearly 2-fold.
MANAGEMENT: Concomitant use of vorapaxar with potent CYP450 3A4 inhibitors should generally be avoided. Some authorities recommend avoiding concomitant use of vorapaxar during and for 2 weeks after treatment with itraconazole.
