Istradefylline and Viramune
Determining the interaction of Istradefylline and Viramune and the possibility of their joint administration.
In the database of official manuals used in the service creation an interaction registered by statistical results of studies was found, which can either lead to negative consequences for the patient health or strengthen a mutual positive effect. A doctor should be consulted to address the issue of joint drug administration.
Consumer:Consumer information for this interaction is not currently available.MONITOR: Coadministration with moderate inducers of CYP450 3A4 may decrease the plasma concentrations of istradefylline, which is primarily metabolized by CYP450 3A4 and 1A1. In study subjects, administration of istradefylline with the potent CYP450 3A4 inducer rifampin (600 mg daily for 20 days) led to a reduction in the peak plasma concentration (Cmax) and total systemic exposure (AUC(inf)) of istradefylline by 45% and 81%, respectively, when compared with istradefylline administered alone. No data are available regarding the effects that other, less potent CYP450 3A4 inducers will have on the pharmacokinetics of istradefylline. MANAGEMENT: Caution is advised if istradefylline is used with moderate CYP450 3A4 inducers. Clinical monitoring of istradefylline should be considered whenever a moderate CYP450 3A4 inducer is added to or withdrawn from therapy. Patients should be monitored for diminished therapeutic effects. References "Product Information. Nourianz (istradefylline)." Kyowa Kirin, Inc, Bedminster, NJ.
