The use of loop diuretics, particularly at high dosages or during chronic therapy, is commonly associated with loss of electrolytes, including potassium, sodium, chloride, magnesium, and calcium. Potassium and magnesium depletion may lead to cardiac arrhythmias and cardiac arrest. Other electrolyte-related complications include metabolic alkalosis and hyponatremia, which are rarely life-threatening. Excessive diuresis, as indicated by rapid weight loss, may induce dehydration and hypovolemia, which can result in acute hypotension, orthostasis, circulatory collapse, vascular thrombosis and embolism, and abrupt reduction in glomerular filtration and renal blood flow. Severe dehydration is most likely to occur in the elderly and patients under prolonged sodium restriction. Therapy with loop diuretics should be administered cautiously in patients with or predisposed to fluid and electrolyte depletion, including patients with primary or secondary aldosteronism may have low potassium levels; those with severe or prolonged diarrhea or vomiting; and those with poor nutritional status. Fluid and electrolyte abnormalities should be corrected before initiating therapy, and blood pressure as well as serum electrolyte concentrations monitored periodically and maintained at normal ranges during therapy. Patients should be advised to immediately report signs and symptoms of fluid or electrolyte imbalance, including dry mouth, thirst, weakness, lethargy, drowsiness, restlessness, muscle pains or cramps, muscular fatigue, hypotension, oliguria, tachycardia, arrhythmia, or gastrointestinal disturbances such as nausea and vomiting. Digitalized patients and patients with a history of ventricular arrhythmias should be monitored carefully, since the development of hypokalemia may be particularly dangerous in these patients. The risk of hypokalemia may be minimized by slow diuresis, a lower diuretic dosage, potassium supplementation, or combined use with a potassium-sparing diuretic. Similarly, to prevent excessive dehydration and hyponatremia, sodium intake should be liberalized if clinically feasible.
Therapy in such patients is best initiated in the hospital. 1 14 Use an aldosterone antagonist or potassium-sparing agent concomitantly with torsemide to prevent hypokalemia and metabolic alkalosis in such patients.

Demadex is indicated for the treatment of hypertension, to lower blood pressure. Lowering blood pressure reduces the risk of fatal and nonfatal cardiovascular events, primarily strokes and myocardial infarctions. These benefits have been seen in controlled trials of antihypertensive drugs from a wide variety of pharmacologic classes including the class to which this drug principally belongs. There are no controlled trials demonstrating risk reduction with Demadex. Elevated systolic or diastolic pressure causes increased cardiovascular risk, and the absolute risk increase per mmHg is greater at higher blood pressures, so that even modest reductions of severe hypertension can provide substantial benefit. Relative risk reduction from blood pressure reduction is similar across populations with varying absolute risk, so the absolute benefit is greater in patients who are at higher risk independent of their hypertension for example, patients with diabetes or hyperlipidemia and such patients would be expected to benefit from more aggressive treatment to a lower blood pressure goal.

Torsemide is not approved for use by anyone younger than 18 years old. In patients with decompensated congestive heart failure, hepatic and renal clearance are both reduced, probably because of hepatic congestion and decreased renal plasma flow, respectively. The total clearance of torsemide is approximately 50% of that seen in healthy volunteers, and the plasma half-life and AUC are correspondingly increased. Because of reduced renal clearance, a smaller fraction of any given dose is delivered to the intraluminal site of action, so at any given dose there is less natriuresis in patients with heart failure than in normal subjects.
Urinary excretion accounts for approximately 20% of total clearance in patients with normal renal function. 1 12 Most renal clearance occurs via active secretion of the drug by the proximal tubules into tubular urine.
