چکیده

FUROSEMIDE (4 chloro-N[2-furyl methyl] -5-sulfamyl-anthranilic acid) (fig. 1) is a new and potent diuretic compound which is effective when given either orally or parenterally. Structurally it has in common with substituted thiazides a sulfamyl-benzene grouping. Animal studies have revealed it to be a most effective diuretic in both rats and dogs, resulting in maximum diuretic effects of up to two thirds of the glomerular filtration rate.1' 2 Clearance data,3 4 micropuncture studies,5 6 and stop-flow analyses7 indicate sites of action in both the proximal and distal tubules, including the ascending limb of the loop of Henle. Toxicological evaluation suggests an extremely wide margin of therapeutic safety.8'9 Clinical studies to date have indicated that it is extremely potent and well tolerated.10-14 The present study was undertaken to investigate the clinical effectiveness of furosemide in various edematous states and to elucidate further the characteristics of its diuretic action.

Real-time urinary electrolyte monitoring after furosemide administration in surgical ICU patients with normal renal function

BACKGROUND Although the loop-diuretic furosemide is widely employed in critically ill patients with known long-term effects on plasma electrolytes, accurate data describing its acute effects on renal electrolyte handling and the generation of plasma electrolyte alterations are lacking. We hypothesized that the long-term effects of furosemide on plasma electrolytes and acid-base depend on its im...

Diuretic Potential of Whole Plant Extracts of Pergularia daemia (Forsk.)

The whole plant, Pergularia daemia (Family: Asclepediaceae), was extracted with 50% alcohol and a fresh batch of the plant material was successively extracted with petroleum ether, ethyl acetate and n-butanol to determine its diuretic activity. The diuretic activity of the different extracts at a dose of 400 mg/Kg was assessed orally in rats with furosemide as a standard drug using Lipschitzs t...
