बुमेटेनाइड और स्पिरोनोलैक्टोन और हाइड्रोक्लोरोथायज़ाइड का इंटरैक्शन

WARNING Bumetanide is a potent diuretic which, if given in excessive amounts, can lead to a profound diuresis with water and electrolyte depletion.

Prevention of hypokalemia requires particular attention in the following conditions: patients receiving digitalis and diuretics for congestive heart failure, hepatic cirrhosis and ascites, states of aldosterone excess with normal renal function, potassium-losing nephropathy, certain diarrheal states, or other states where hypokalemia is thought to represent particular…

In these test animals bumetanide was 5 to 6 times more potent than furosemide and, since the diuretic potency of bumetanide is about 40 to 60 times furosemide, it is anticipated that blood levels necessary to produce ototoxicity will rarely be achieved.

Like other members of this class of diuretics, bumetanide probably shares this risk.

Lithium Lithium should generally not be given with diuretics (such as bumetanide) because they reduce its renal clearance and add a high risk of lithium toxicity.

CONTRAINDICATIONS Spironolactone and hydrochlorothiazide tablets are contraindicated in patients with anuria, acute renal insufficiency, significant impairment of renal excretory function, hypercalcemia, hyperkalemia, Addison's disease, and in patients who are allergic to thiazide diuretics or to other sulfonamide-derived drugs.

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…

Spironolactone, when used with ACE inhibitors or indomethacin, even in the presence of a diuretic, has been associated with severe hyperkalemia.

Lithium generally should not be given with diuretics (see Precautions: Drug interactions ).

Diuretic agents reduce the renal clearance of lithium and add a high risk of lithium toxicity.
