Rapamune Tablets and Tegretol

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.

CarBAMazepine may significantly reduce the blood levels of sirolimus, which may make the medication less effective in treating your condition. Talk to your doctor if you have any questions or concerns. Your doctor may be able to prescribe alternatives that do not interact. 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.

GENERALLY AVOID: Coadministration with potent inducers of CYP450 3A4 and/or P-glycoprotein may significantly decrease the plasma concentrations and pharmacologic effects of sirolimus. The mechanism probably involves reduced absorption as well as accelerated clearance of sirolimus due to induction of both intestinal P-glycoprotein drug efflux transporter and hepatic/intestinal CYP450 3A4 isoenzymes. In a study of 14 healthy volunteers, a potent inducer of CYP450 3A4 and P-gp, rifampin (600 mg daily for 14 days) increased the oral clearance of sirolimus (20 mg single dose) by 5.5-fold, representing mean decreases in peak blood concentration (Cmax) and area under the concentration-time curve (AUC) of 71% and 82%, respectively.

MANAGEMENT: Given the risk of organ rejection associated with inadequate immunosuppressant levels, the use of sirolimus with potent inducers of CYP450 3A4 and/or P-gp is not recommended. Alternative therapeutic agents with less enzyme induction potential should be considered.
