स्पिरोनोलैक्टोन और हाइड्रोक्लोरोथायज़ाइड और ट्रायमटेरिन का इंटरैक्शन

Information for patients Patients who receive spironolactone and hydrochlorothiazide tablets should be advised to avoid potassium supplements and foods containing high levels of potassium including salt substitutes.

Concomitant administration of spironolactone and hydrochlorothiazide tablets with the following drugs or potassium sources may lead to severe hyperkalemia: • other potassium-sparing diuretics • ACE inhibitors • angiotensin II receptor antagonists • aldosterone blockers • non-steroidal anti-inflammatory drugs (NSAIDs), e.g., indomethacin • heparin and low molecular…

Thiazides may add to or potentiate the action of other antihypertensive drugs.

Drug interactions ACE inhibitors, Angiotensin II receptor antagonists, aldosterone blockers, potassium supplements, heparin, low molecular weight heparin, and other drugs known to cause hyperkalemia: Concomitant administration may lead to severe hyperkalemia.

Two deaths have been reported in patients receiving concomitant spironolactone and Dyrenium or Dyazide ® .

Dyrenium should not be given to patients receiving other potassium-sparing agents, such as spironolactone, amiloride hydrochloride, or other formulations containing triamterene.

If the ECG shows no widening of the QRS or arrhythmia in the presence of hyperkalemia, it is usually sufficient to discontinue Dyrenium (triamterene) and any potassium supplementation, and substitute a thiazide alone.

Drug Interactions Caution should be used when lithium and diuretics are used concomitantly because diuretic-induced sodium loss may reduce the renal clearance of lithium and increase serum lithium levels with risk of lithium toxicity.

The effects of the following drugs may be potentiated when given together with triamterene: antihypertensive medication, other diuretics, preanesthetic and anesthetic agents, skeletal muscle relaxants (non-depolarizing).
