التداخل بين أميلوريد وأولميسارتان وهيدروكلوروثيازيد

Hyperkalemia occurs commonly (about 10%) when amiloride is used without a kaliuretic diuretic.

When amiloride HCl is used concomitantly with a thiazide diuretic in patients without these complications, the risk of hyperkalemia is reduced to about 1-2 percent.

It is thus essential to monitor serum potassium levels carefully in any patient receiving amiloride, particularly when it is first introduced, at the time of diuretic dosage adjustments, and during any illness that could affect renal function.

The risk of hyperkalemia may be increased when potassium-conserving agents, including amiloride HCl, are administered concomitantly with an angiotensin-converting enzyme inhibitor, an angiotensin II receptor antagonist, cyclosporine or tacrolimus.

Diabetes Mellitus In diabetic patients, hyperkalemia has been reported with the use of all potassium-conserving diuretics, including amiloride HCl, even in patients without evidence of diabetic nephropathy.

Hypotension in Volume or Salt-Depleted Patients In patients with an activated renin-angiotensin system, such as volume-or salt-depleted patients ( e.g., those being treated with high doses of diuretics), symptomatic hypotension may occur after initiation of treatment with olmesartan medoxomil and hydrochlorothiazide tablets.

• Non-Steroidal Anti-Inflammatory Drugs (NSAIDs): Reduced diuretic, natriuretic and antihypertensive effects; increased risk of renal toxicity ( 7.3 )

Non-Steroidal Anti-Inflammatory Agents Including Selective Cyclooxygenase-2 Inhibitors (COX-2 Inhibitors) Olmesartan medoxomil 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…

Hydrochlorothiazide In some patients the administration of an NSAID can reduce the diuretic, natriuretic, and antihypertensive effects of thiazide diuretics.

Use of Hydrochlorothiazide with Other Drugs 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.
