Immunosuppressants everolimus, rapamycin (also known as sirolimus), temsirolimus budesonide, ciclesonide, cyclosporine, dexamethasone, fluticasone, methylprednisolone, tacrolimus Rapamycin (sirolimus): Ketoconazole tablets 200 mg daily for 10 days increased the C max and AUC of a single 5 mg dose of sirolimus by 4.3 fold and 10.9 fold, respectively in 23 healthy…

Co-administration with Inducers or Inhibitors of CYP3A Metabolism Agents Inducing CYP3A Metabolism: Strong inducers of CYP3A4/5 such as dexamethasone, carbamazepine, phenytoin, phenobarbital, rifampin, rifabutin, and rifampacin may decrease exposure of the active metabolite, sirolimus.

Agents Inhibiting CYP3A Metabolism: Strong CYP3A4 inhibitors such as atazanavir, clarithromycin, indinavir, itraconazole, ketoconazole, nefazodone, nelfinavir, ritonavir, saquinavir, and telithromycin may increase blood concentrations of the active metabolite sirolimus.

Strong inducers of CYP3A4/5 and inhibitors of CYP3A4 may affect concentrations of the primary metabolite of TORISEL.

Agents Inhibiting CYP3A Metabolism Co-administration of TORISEL with ketoconazole, a potent CYP3A4 inhibitor, had no significant effect on temsirolimus C max or AUC; however, sirolimus AUC increased 3.1-fold, and C max increased 2.2-fold compared to TORISEL alone.
