Temsirolimus ve Verapamil etkileşimi

With concomitant use of mTOR inhibitors (e.g., sirolimus, temsirolimus, and everolimus) and verapamil, consider appropriate dose reductions of both medications.

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.

Monitor patients for signs and symptoms of angioedema when temsirolimus is given concomitantly with angiotensin converting enzyme (ACE) inhibitors (e.g., ramipril) or calcium channel blockers (CCB) (e.g., amlodipine).

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

Angioedema with ACE inhibitors and Calcium Channel Blockers Angioedema has been reported in patients taking mammalian target of rapamycin (mTOR) inhibitors in combination with ramipril and/or amlodipine.
