Lack of effect of bumetanide on body potassium content in hypertension

1 Twelve patients with mild hypertension were treated with bumetanide for a six-month period. No evidence was found of hypokalaemia or decreased total exchangeable potassium in subjects with or without additional potassium supplements. 2 Bumetanide was well tolerated by all patients. It caused hyperuricaemia but no episodes of gout occurred. Minor abnormalities of liver function were noted. 3 Bumetanide did not have a sustained antihypertensive action.
