Interactions between your drugs

Moderate

omeprazole glecaprevir

Applies to: omeprazole and Mavyret (glecaprevir / pibrentasvir)

MONITOR: Coadministration with omeprazole may decrease the plasma concentrations of glecaprevir. The mechanism of interaction has not been established. When a single 300 mg-120 mg dose of glecaprevir-pibrentasvir was administered with omeprazole 20 mg once daily to 9 study subjects, glecaprevir peak plasma concentration (Cmax) and systemic exposure (AUC) decreased by 22% and 29%, respectively. When the dose of glecaprevir-pibrentasvir was administered with omeprazole 40 mg once daily (one hour before glecaprevir-pibrentasvir) to 12 study subjects, glecaprevir Cmax decreased by 64% and AUC decreased by 51%. The pharmacokinetics of pibrentasvir were not affected.

MANAGEMENT: According to the manufacturer, no dosage adjustment is necessary for glecaprevir-pibrentasvir during coadministration with omeprazole. However, the potential for diminished pharmacologic effects of glecaprevir-pibrentasvir should be considered during coadministration with higher dosages of omeprazole. Alternative treatments may be required if an interaction is suspected.

Drug and food interactions

Moderate

glecaprevir food

Applies to: Mavyret (glecaprevir / pibrentasvir)

ADJUST DOSING INTERVAL: Food enhances the oral bioavailability of glecaprevir and pibrentasvir. Relative to fasting conditions, mean glecaprevir systemic exposure (AUC) increased by 83% to 163% and mean pibrentasvir AUC increased by 40% to 53% when administered with moderate to high fat meals.

MANAGEMENT: Glecaprevir-pibrentasvir 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.
