- Trade name: Zaroxolyn, utilized primarily for hypertension and edema management.
- Classified as an antihypertensive and diuretic, specifically a thiazide-like diuretic.
Indications
- Effective for mild to moderate hypertension.
- Addresses edema linked to heart failure (HF) and nephrotic syndrome.
Mechanism of Action
- Reduces blood pressure in hypertensive individuals.
- Promotes diuresis, aiding in the mobilization of edema.
- Efficacy persists even in cases of renal impairment.
Contraindications
- Not suitable for individuals with hypersensitivity or anuria.
- Caution advised for those with a history of sulfonamide allergies.

- Not established as safe in patients with significant liver issues.
- Increased sensitivity to drug effects may occur in certain populations.
Adverse Effects
- Common side effects include lethargy, chest pain, hypotension, and palpitations.
- Gastrointestinal disturbances like bloating and cramping may occur.
- Other serious adverse reactions can include drug-induced hepatitis, pancreatitis, and varied electrolyte imbalances (e.g., hyperglycemia, hypokalemia, etc.).
Drug Interactions
- Increased hypotension risk when combined with nitrates or alcohol.
- Risk of hypokalemia heightened with corticosteroids and certain antibiotics.
- Potential for digoxin toxicity enhancement due to potassium depletion.
- Food intake may affect absorption rates of the medication.
Patient Assessment
- Continuous monitoring of blood pressure, daily weight, and fluid intake/output is crucial.
- Assess for edema in extremities, especially in patients on digoxin to prevent toxicity.
- Evaluate for allergy history to sulfonamides and monitor compliance via prescription refills.
Laboratory Test Considerations
- Regular monitoring of electrolytes (especially potassium), blood glucose, and renal function is necessary.
- May affect glucose levels, bilirubin, calcium, and various serum levels noted in laboratory tests.
- Expected lab alterations include an increase in cholesterol and triglycerides.
Patient Education
- Instruct patients to take metolazone consistently at the same time each day, adhering to missed dose guidelines (do not double doses).
- Advise on biweekly weight monitoring and the importance of dietary potassium discussions.
- Emphasize continued medication adherence for chronic hypertension management and instruct on proper blood pressure monitoring techniques.
