Interactions between your drugs

Moderate

rufinamide benzgalantamine

Applies to: rufinamide and Zunveyl (benzgalantamine)

Consumer information for this interaction is not currently available.

MONITOR: Rufinamide may modestly or moderately decrease the plasma concentrations and therapeutic effects of drugs that are CYP450 3A4 substrates. The mechanism is enhanced metabolism by CYP450 3A4 enzyme induction. Enzyme induction is more pronounced with larger doses of rufinamide. After treatment with rufinamide 400 mg twice daily for 11 days, the clearance of triazolam was increased by 55% and the exposure was decreased by 36%.

MANAGEMENT: During concomitant treatment with rufinamide and drugs that are CYP450 3A4 substrates, it is recommended that patients should be monitored for 2 weeks when rufinamide is added to or withdrawn from therapy, or after increases of the dose. Dose adjustments of the coadministered drug may be required if an interaction is suspected. The manufacturer also recommends that monitoring should be considered during concomitant use of drugs with a narrow therapeutic index, including digoxin and warfarin.

Drug and food interactions

rufinamide food
