C
Description
Animal reproduction studies have shown an adverse effect on the fetus and there are no adequate and well-controlled studies in humans, but potential benefits may warrant use of the drug in pregnant women despite potential risks
Mode of Action
Bumetanide induces diuresis by inhibiting reabsorption of water and electrolytes (sodium and chloride) in the ascending loop of Henle and proximal renal tubule.
Interaction
Reduced diuretic and natriuretic actions by probenecid. Indometacin blunts action of bumetanide; concurrent usage with antihypertensives may increase risk of orthostatic hypotension.
Potentially Fatal: Avoid concurrent usage with ototoxic drugs such as aminoglycoides and nephrotoxic drugs. Reduced lithium excretion via kidneys.
