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 ...

When diuretic-based stepped care was first advocated for the treatment of hypertension, there were fewer classes of antihypertensive medication than there are today. In 1984, the third Joint National Committee on Detection, Evaluation, and Treatment of High Blood Pressure (JNC) for the first time suggested an alternative initial treatment with a /3-blocker in selected hypertensive patients, and...

In 4 patients with cirrhosis and ascites, diuretic therapy resulted in an impairment of renal function that was associated with a rise in plasma renin activity (PRA). In 3, this occurred in the absence of volume depletion. When diuretics were discontinued, renal function returned to normal. beta-adrenergic blocking drugs were then given to suppress renin secretion and diuretics restarted. On th...

Purpose: The present study was undertaken to investigate diuretic effect of aqueous and methanol extracts of the dried seeds of erythrina indica in normal rats. Method: Aqueous and methanol extracts of erythrina indica seeds were administered to experimental rats orally at doses of 25 and 30 ml/kg p.o. Furosemide (10 mg/kg) was used as positive control in the study. The diuretic effect of the e...

A lthough thiazide and thiazide-like diuretics are indispensable drugs in the treatment of hypertension, their role as first-line or even second-line drugs is a provoking debate. The European Society of Cardiology/ European Society of Hypertension (ESC/ ESH) guidelines recommend that thiazide diuretics should be considered as suitable as b-blockers, calcium antagonists, ACE inhibitors, and angi...

In vivo effects of cannabinoid (CB) agonists are often assessed using four well-established measures: locomotor activity, hypothermia, cataleptic-like effects, and analgesia. The present studies demonstrate that doses of CB agonists that produce these effects also reliably increase diuresis. Diuretic effects of several CB agonists were measured in female rats over 2 hours immediately after drug...

A new loop diuretic with uricosuric activity, 6,7-dichloro-5-(N,N-dimethylsulfamoyl)-2,3-dihydro-2-benzofuran carboxylic acid (S-8666), was given orally at 12:00 a.m. or 12:00 p.m. in rats. The diuretic of S-8666 and the urinary excretions of the drug and its active metabolite S-8680 (N-demethyl S-8666) were greater at 12:00 a.m. than at 12:00 p.m. Thus, the present study indicates that the diu...

Background Congestive heart failure (CHF) in patients and experimental animals is characterized by renal retention of salt and water and a blunted natriuretic/diuretic response to atrial natriuretic peptide (ANP). Recently, we reported that chronic treatment with the PPARgagonist rosiglitazone (RGZ) improved the natriuretic and diuretic responses to extracellular fluid volume expansion in rats ...

Hyponatremia frequently poses a therapeutic challenge in acute decompensated heart failure (ADHF). Treating physicians should differentiate between depletional versus dilutional hyponatremia. The former is caused by diuretic agents, which enhance sodium excretion, often with concomitant potassium/magnesium losses. This can be treated with isotonic saline, whereas potassium/magnesium administrat...

The treatment of edema in patients with nephrotic syndrome is generally managed by dietary sodium restriction and loop diuretics. However, edema does not improve in some patients despite adequate sodium restriction and maximal dose of diuretics. In such patients, combination of albumin and a loop diuretic may improve edema by diuresis and natriuresis. The response to this combination of albumin...
