- sofpironium topical
Interactions between your drugs
ranolazine sofpironium topical
Applies to: Aspruzyo Sprinkle (ranolazine) and sofpironium topical
MONITOR: Coadministration with inhibitors of CYP450 2D6 may increase the plasma concentrations of topical sofpironium, which has been shown to be partially metabolized by the isoenzyme. In a pharmacokinetic study in patients with primary axillary hyperhidrosis, sofpironium systemic exposure (AUC) and peak plasma concentration (Cmax) increased approximately 2-fold following concomitant use with the potent CYP450 2D6 inhibitor paroxetine at a 20 mg oral dose. Clinical data for sofpironium use in combination with other less potent CYP450 2D6 inhibitors are not available.
MANAGEMENT: Caution is advised when sofpironium topical is used concurrently with CYP450 2D6 inhibitors. Patients should be more closely monitored for adverse effects such as blurred vision, urinary retention, difficulty controlling body temperature in warm environments, and dry mouth.

Drug and food interactions
ranolazine food
Applies to: Aspruzyo Sprinkle (ranolazine)
GENERALLY AVOID: Grapefruit and grapefruit juice may significantly increase the plasma concentrations of orally administered ranolazine. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruit. Because ranolazine prolongs QT interval in a dose-dependent manner, high plasma levels of ranolazine may increase the risk of ventricular arrhythmias such as ventricular tachycardia, ventricular fibrillation, and torsade de pointes.
MANAGEMENT: Patients treated with ranolazine should avoid consumption of grapefruit juice and other grapefruit products if possible. Otherwise, the dosage of ranolazine should be limited to 500 mg twice a day.
