Edit list (add/remove drugs)

Interactions between your drugs

Moderate

simeprevir momelotinib

Applies to: Olysio (simeprevir) and momelotinib

MONITOR: Coadministration with inhibitors of organic anion transporting polypeptides (OATP) 1B1 and/or 1B3 may increase the plasma concentrations and effects of momelotinib, which is a substrate of the hepatic uptake transporters. Clinical studies have demonstrated that concomitant use with a single dose of the OATP1B1/B3 inhibitor rifampin increased the peak plasma concentration (Cmax) and systemic exposure (AUC) of momelotinib by 40% and 57% respectively. The Cmax and AUC of the active metabolite of momelotinib, M21, was also increased, by 6% and 12%, respectively.

MANAGEMENT: Caution is advised if momelotinib is used in combination with inhibitors of OATP1B1 and/or 1B3. Dosage adjustments of momelotinib may be required. Patients should be advised to report any momelotinib-related adverse reactions such as bacterial or viral infection, thrombocytopenia, neutropenia, hepatotoxicity, thrombosis, and adverse cardiovascular events.

Drug and food interactions

Moderate

simeprevir food

Applies to: Olysio (simeprevir)

ADJUST DOSING INTERVAL: Food significantly enhances the oral bioavailability of simeprevir, although the type of food does not seem to matter. In healthy study subjects, administration of simeprevir after a high-fat, high-caloric (928 kcal) breakfast increased systemic exposure (AUC) by 61% and delayed absorption by 1 hour, while administration after a normal caloric (533 kcal) breakfast increased AUC by 69% and delayed absorption by 1.5 hours.

MANAGEMENT: To ensure maximal oral absorption, simeprevir should be administered with 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.
