Study Notes
Torsemide Overview
- Brand name: Demadex
- Drug class: Loop diuretic
Dosing Information
- For edema related to heart failure, renal failure, hepatic cirrhosis: initial dose of 10-20 mg PO daily (titrate to max 200 mg/d)
- For hypertension: starting dose of 5 mg PO daily, titrate based on patient response
Mechanism of Action
- Acts as a loop diuretic, inhibiting sodium reabsorption in the thick ascending limb of Henle's loop
- Competes for the chloride site on the Na+-K+-2Cl- cotransporter
Renal Dose Adjustment
- No adjustments required for renal impairment
Pharmacogenetics
- No known pharmacogenetic implications
Contraindications
- Hypersensitivity to torsemide or sulfonylureas
- Anuria
- Hepatic coma
Boxed Warnings
- None specified
Drug Interactions
- ACE-inhibitors: Increased risk of postural hypotension; start with a low dose and monitor blood pressure
- Aminoglycosides: May increase serum concentrations, leading to ototoxicity and/or nephrotoxicity; avoid use
- Antidiabetic drugs: May reduce hypoglycemic effects; monitor closely
- Antiarrhythmic agents: Increased risk of ventricular arrhythmias due to hypokalemia; monitor potassium and magnesium levels
- Bile acid resins: Reduced efficacy of torsemide; advise administration of cholestyramine 4 hours after torsemide
- Diuretics: Can lead to increased diuretic response; monitor usage
- Lithium: Increased risk of lithium toxicity; consider reducing lithium dose
- NSAIDs: Reduced antihypertensive effect, potential nephrotoxicity; avoid concurrent use
Adverse Reactions
- Common adverse reactions: None reported
- Rare but serious reactions: Angioedema, thrombocytopenia, electrolyte abnormalities, anuria
Efficacy Monitoring Parameters
- Target outcomes include decreased blood pressure, increased urine output, reduction in edema, and daily weight monitoring
- For renal failure treatment, monitor increase in urine volume, creatinine clearance (CrCl), blood urea nitrogen (BUN), and electrolyte levels
Toxicity Monitoring Parameters
- Monitor for severe volume depletion and check serum and urine electrolytes, uric acid, and blood glucose at baseline and every 3-6 months post-therapy
