Interactions between your drugs

Minor

simeprevir niraparib

Applies to: simeprevir and niraparib

Coadministration of niraparib with a P-glycoprotein (P-gp) and/or Breast Cancer Resistance Protein (BCRP) inhibitor may increase the plasma concentration of niraparib, which is a substrate of these efflux transporters. However, due to the high permeability and bioavailability of niraparib, the risk of a clinically relevant interaction with inhibitors of these transporters is unlikely. No dose adjustment is recommended if a P-gp and/or BCRP inhibitor is added to treatment with niraparib.

Drug and food interactions

Moderate

simeprevir food

Applies to: 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.
