Interactions between your drugs
oritavancin lesinurad
Applies to: oritavancin and Duzallo (allopurinol / lesinurad)
Consumer information for this interaction is not currently available.
MONITOR: Coadministration with inhibitors of CYP450 2C9 may increase the plasma concentrations of lesinurad, which is primarily metabolized by the isoenzyme. According to the manufacturer, administration of lesinurad with the moderate CYP450 2C9 inhibitor fluconazole (200 mg daily) increased lesinurad peak plasma concentration (Cmax) and systemic exposure (AUC) by approximately 35% and 55%, respectively, compared to administration of lesinurad alone. In a cross-study pharmacogenomic analysis conducted in patients receiving single or multiple doses of lesinurad, patients who were deficient in CYP450 2C9 activity (i.e., CYP450 2C9 poor metabolizers) had an approximately 1.8-fold higher exposure to lesinurad at the 400 mg dose than extensive metabolizers.
MANAGEMENT: Caution is advised when lesinurad is prescribed with CYP450 2C9 inhibitors. Patients should be closely monitored for adverse renal effects such as serum creatinine elevations, renal function impairment, and nephrolithiasis. It may be advisable to avoid concomitant use with a potent CYP450 2C9 inhibitor such as gemfibrozil.
Drug and food interactions
allopurinol food
Applies to: Duzallo (allopurinol / lesinurad)
Allopurinol should generally be taken after a meal to reduce side effects. If your daily dose exceeds 300 mg, you may also ask your healthcare provider if it is okay to divide the total daily dose into smaller doses given more frequently instead of once a day, as this may also reduce stomach upset that can happen with allopurinol. It is best to avoid or limit the consumption of alcohol, as it can increase drowsiness or other nervous system side effects of allopurinol. You should also avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medication affects you. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
