Relevance: 27.11.2022 Reviewer: Shkutko P.M., M.D., in

In the database of official manuals used in the service creation an interaction registered by statistical results of studies was found, which can either lead to negative consequences for the patient health or strengthen a mutual positive effect. A doctor should be consulted to address the issue of joint drug administration.

Consumer:

Somatropin may reduce the blood levels and effects of aprepitant. Contact your doctor if your symptoms worsen or your condition changes during treatment with these medications. Your doctor may be able to prescribe alternatives that do not interact, or you may need a dose adjustment or more frequent monitoring to safely use both medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Professional:

MONITOR: Coadministration with inducers of CYP450 3A4 may decrease the plasma concentrations of aprepitant, which is primarily metabolized by the isoenzyme. According to the product labeling, administration of a single 375 mg dose of aprepitant on day 9 of treatment with the potent CYP450 3A4 inducer rifampin (600 mg/day for 14 days) resulted in an 11-fold decrease in aprepitant systemic exposure (AUC) and 3-fold decrease in the mean terminal half-life.

MANAGEMENT: The possibility of diminished therapeutic response to aprepitant should be considered during coadministration with CYP450 3A4 inducers, particularly potent ones like carbamazepine, enzalutamide, mitotane, phenobarbital, phenytoin, rifampin, and St. John's wort. Pharmacologic response to aprepitant should be monitored more closely whenever a CYP450 3A4 inducer is added to or withdrawn from therapy, and the dosage adjusted as necessary.
