Interactions between your drugs

Moderate

OXcarbazepine glecaprevir

Applies to: oxcarbazepine and glecaprevir / pibrentasvir

MONITOR: Coadministration with inducers of P-glycoprotein (P-gp) or CYP450 3A4 may decrease the plasma concentrations of glecaprevir and pibrentasvir. Both antiviral agents are substrates of the P-gp efflux transporter, and glecaprevir is additionally a substrate of the CYP450 3A4 isoenzyme. When a single 300 mg-120 mg dose of glecaprevir-pibrentasvir was administered to 12 study subjects following multiple dosing of the potent inducer rifampin at 600 mg once daily, glecaprevir peak plasma concentration (Cmax) and systemic exposure (AUC) decreased by 86% and 88%, respectively, while pibrentasvir Cmax and AUC decreased by 83% and 87%, respectively. Likewise, when a single dose of glecaprevir-pibrentasvir was administered to 10 study subjects following multiple dosing of carbamazepine 200 mg twice daily, glecaprevir Cmax and AUC decreased by approximately two-thirds, while pibrentasvir Cmax and AUC decreased by approximately one-half.

MANAGEMENT: The potential for diminished pharmacologic effects of glecaprevir and pibrentasvir should be considered during coadministration with CYP450 3A4 inducers. Alternative treatments may be required if an interaction is suspected.

Drug and food interactions

Moderate

OXcarbazepine food

Applies to: oxcarbazepine

GENERALLY AVOID: Alcohol may potentiate some of the pharmacologic effects of CNS-active agents. Use in combination may result in additive central nervous system depression and/or impairment of judgment, thinking, and psychomotor skills.

MANAGEMENT: Patients receiving CNS-active agents should be warned of this interaction and advised to avoid or limit consumption of alcohol. Ambulatory patients should be counseled to avoid hazardous activities requiring complete mental alertness and motor coordination until they know how these agents affect them, and to notify their physician if they experience excessive or prolonged CNS effects that interfere with their normal activities.

glecaprevir food

Applies to: 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.
