Interactions between your drugs

Minor

ezogabine vibegron

Applies to: ezogabine and vibegron

Coadministration with moderate or potent inhibitors of CYP450 3A4 and/or P-glycoprotein (P-gp) may increase the plasma concentrations (AUC) of vibegron, which has been shown in vitro to be a substrate of the isoenzyme and transporter. Although CYP450 3A4 is the predominant enzyme in vibegron metabolism, metabolic pathways have only a minor role in the elimination of vibegron. In a phase 3 Japanese study, coadministration of vibegron (100 mg) with moderate (diltiazem) and potent (ketoconazole) inhibitors of CYP450 3A4, resulted in a 1.6- and 2.1-fold increase in vibegron AUC, respectively, which was not considered clinically significant. No dosage adjustment is recommended when vibegron is administered in combination with moderate or potent CYP450 3A4 and/or P-gp inhibitors.

Drug and food interactions

Moderate

ezogabine food

Applies to: ezogabine

GENERALLY AVOID: Alcohol may increase the plasma concentrations of ezogabine. In a study of healthy volunteers, the administration of ezogabine 200 mg in combination with ethanol 1g/kg (5 standard alcohol drinks) over 20 minutes resulted in an increase in the ezogabine peak plasma concentration (Cmax) and systemic exposure (AUC) by 23% and 37%, respectively.

Food does not significantly affect the bioavailability of ezogabine. According to the product labeling, high-fat food does not affect the extent to which ezogabine is absorbed, but increases peak plasma concentration (Cmax) by approximately 38% and delays the time to reach peak concentration (Tmax) by 0.75 hour.

MANAGEMENT: In general, alcohol consumption should be avoided or limited during treatment with CNS-depressant agents. Patients should be advised of the potential for increased dose-related adverse reactions of ezogabine (e.g., dizziness, somnolence, nausea, constipation, urinary retention, blurred vision, memory impairment, tremor) when taken with alcohol, and to avoid hazardous activities that require mental alertness and motor coordination until they know how the medication affects them. Ezogabine can be taken with or without food.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
