1 The effects of high doses of piretanide, a new diuretic agent chemically related to frusemide and bumetanide were evaluated in twelve patients with severe chronic renal insufficiency (creatinine clearance below 25 ml/min). 2 Patients received either 30 mg or 60 mg piretanide orally after a water load of 11. Urine volume and the excretion of electrolytes, creatinine, urea and uric acid were measured over the subsequent 24 h. 3 Piretanide produced an effective diuresis and natriuresis in these patients, its action being broadly similar to those of bumetanide and frusemide observed in previous studies.
