Torasemide, a new loop diuretic, in patients with chronic renal failure.

Torasemide, a new loop diuretic, was administered in 9 hospitalized patients with chronic renal failure to treat both arterial hypertension and peripheral edema. The urine of 5 patients was collected over 12-hour periods to assess the long-lasting diuretic activity of torasemide. Torasemide induced a significant decrease in blood pressure and reversion of peripheral edema in all patients without adverse effects. Torasemide is a high-ceiling loop diuretic, useful in correcting extracellular fluid volume expansion in patients with chronic renal failure.
