At a glance
Metolazone is a thiazide-like diuretic used to treat hypertension and edema (fluid overload) associated with heart, liver, kidney, or lung disease.
Indications
- Hypertension (high blood pressure)
- Edema (fluid overload) associated with heart failure, liver, kidney, or lung disease
- Edema associated with nephrotic syndrome
- Edema associated with renal disease
Pharmacology
Metolazone is a quinazoline diuretic with properties generally similar to thiazide diuretics. It acts primarily to inhibit sodium reabsorption at the cortical diluting site and to a lesser extent in the proximal convoluted tubule. Sodium and chloride ions are excreted in approximately equivalent amounts. It does not inhibit carbonic anhydrase.

- Edema (Renal Disease): 5-20 mg daily
- Elderly: Initial: 2.5 mg/day or every other day
Child Dose: 0.2-0.4 mg/kg/day (single daily dose or divided q12hr)
