Eplerenon ve Verapamil etkileşimi

…Patients Eplerenone is contraindicated in all patients with: • serum potassium > 5.5 mEq/L at initiation, • creatinine clearance ≤ 30 mL/min, or • concomitant administration of strong CYP3A inhibitors (e.g., ketoconazole, itraconazole, nefazodone, troleandomycin, clarithromycin, ritonavir, and nelfinavir) [see Drug Interactions (7.1) , Clinical Pharmacology (12.3)…

• Concomitant use with strong CYP3A inhibitors ( 4 , 7.1 )

Patients on moderate CYP3A inhibitors that cannot be avoided should have their dose of eplerenone reduced [see Drug Interactions (7.2) ] .

Do not use eplerenone with drugs that are strong inhibitors of CYP3A [see Contraindications (4) and Clinical Pharmacology (12.3) ] .

• Hyperkalemia: Patients with decreased renal function, diabetes, proteinuria or patients who are taking ACEs and ARBs, NSAIDs or moderate CYP3A inhibitors are at increased risk.

Control patients with milder ventricular dysfunction, if possible, with optimum doses of digitalis and/or diuretics before verapamil treatment is started [see Drug Interactions ( 7.5 )] .

Antihypertensive Agents Verapamil administered concomitantly with oral antihypertensive agents (e.g., vasodilators, angiotensin-converting enzyme inhibitors, diuretics, beta blockers) will usually have an additive effect on lowering blood pressure.
