Interactions between your drugs

Moderate

esomeprazole lenacapavir

Applies to: esomeprazole and lenacapavir

MONITOR: Coadministration with lenacapavir may increase the plasma concentrations of drugs that are substrates of the CYP450 3A4 isoenzyme. According to the manufacturer, lenacapavir is a moderate inhibitor of CYP450 3A4 and due to its long half-life after subcutaneous administration, it may increase the exposure to and risk of adverse reactions to drugs primarily metabolized by CYP450 3A4 that are initiated within 9 months after the last subcutaneous lenacapavir dose. In pharmacokinetic studies in fed subjects without HIV, coadministration of oral lenacapavir (600 mg twice daily for 2 days, then a single 600 mg dose) with the sensitive CYP450 3A4 substrate midazolam (single 2.5 mg dose orally at the same time as the single lenacapavir dose) led to an increase in midazolam peak plasma concentration (Cmax) and systemic exposure (AUC) by 1.9-fold and 3.6-fold, respectively.

MANAGEMENT: Caution is advised if lenacapavir is coadministered with drugs that are substrates of CYP450 3A4, particularly sensitive substrates or those with a narrow therapeutic index. Due to its long half-life, the effect may persist for up to 9 months after the last subcutaneous dose, so caution and monitoring for adverse effects are also advised during this time. The prescribing information for the coadministered drug should also be consulted for specific dosing recommendations.

Drug and food interactions

Moderate

esomeprazole food

Applies to: esomeprazole

ADJUST DOSING INTERVAL: Food may interfere with the absorption of esomeprazole. The manufacturer reports that the area under the concentration-time curve for esomeprazole following a single 40 mg dose was 33% to 53% lower when administered after food intake as opposed to during fasting conditions.

MANAGEMENT: Esomeprazole should be taken at least one hour before meals. When administered to patients receiving continuous enteral nutrition, some experts recommend that the tube feeding should be interrupted for at least 1 hour before and 1 hour after the dose of esomeprazole is given.

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.
