Interaction entre Éplérénone et Olmésartan, amlodipine et hydrochlorothiazide

…• serum creatinine > 2.0 mg/dL in males or >1.8 mg/dL in females, • creatinine clearance < 50 mL/min, or • concomitant administration of potassium supplements or potassium-sparing diuretics (e.g., amiloride, spironolactone, or triamterene) [see Warnings and Precautions (5.1) , Adverse Reactions (6.2) , Drug Interactions (7) , and Clinical Pharmacology (12.3)…

• Concomitant use of potassium supplements or potassium-sparing diuretics ( 4 )

• 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.

Hyperkalemia The risk of hyperkalemia is higher in patients with impaired renal function, proteinuria, diabetes and those concomitantly treated with ACEs, ARBs, NSAIDs and moderate CYP3A inhibitors.

ACE Inhibitors and Angiotensin II Receptor Antagonists The risk of hyperkalemia increases when eplerenone is used in combination with an ACE inhibitor and/or an ARB.

In patients with an activated renin-angiotensin system, such as volume- and/or salt-depleted patients (e.g., those being treated with high doses of diuretics) symptomatic hypotension may be anticipated after initiation of treatment with olmesartan medoxomil.

• NSAIDs: Can reduce the diuretic, natriuretic, and antihypertensive effects of diuretics.

…Medoxomil Non-Steroidal Anti-Inflammatory Agents including Selective Cyclooxygenase-2 Inhibitors (COX-2 Inhibitors): In patients who are elderly, volume-depleted (including those on diuretic therapy), or with compromised renal function, co-administration of NSAIDs, including selective COX-2 inhibitors, with angiotensin II receptor antagonists, including olmesartan…

Lithium: Increases in serum lithium concentrations and lithium toxicity have been reported with concomitant use of olmesartan or thiazide diuretics.

Drug Interactions with Hydrochlorothiazide When administered concurrently the following drugs may interact with thiazide diuretics: Antidiabetic Drugs (oral agents and insulin): Dosage adjustment of the antidiabetic drug may be required.
