- Edema
- Chronic heart failure
- Chronic Kidney Diseases
- Nephrotic Syndrome
Dosing
Heart failure with reduced ejection fraction Initiate at 20 mg once daily; may increase to 37.5 mg once daily as clinically indicated; may reduce to 20 mg every other day if hyperkalemia develops; consider initiating at 10 mg once daily in patients with eGFR 30-50 mL/min/1.73m2.
Hypertensive disease Initiate at 20 to 75 mg daily in single or divided doses; titrate at two-week intervals; doses >75 mg/day generally do not provide additional blood pressure reduction.
Edema Initiate in a hospital setting at 75 mg daily in single or divided doses; titrate slowly; administer for at least five days before increasing dose to obtain desired effect.
Edema, Chronic heart failure, Chronic Kidney Diseases, Nephrotic Syndrome 30 mg subcutaneously over the first hour followed by 12.5 mg per hour for the subsequent 4 hours (total 80 mg) via On-body Infusor applied to the abdomen; not for chronic use, replace with oral diuretics as soon as practical.

Pharmacology
Aldosterone antagonist; spironolactone and its active metabolites competitively bind aldosterone receptors at the sodium-potassium exchange site in the distal convoluted renal tubule, increasing sodium and water excretion while retaining potassium, exerting diuretic and antihypertensive effects.
Furosemide is a loop diuretic that primarily inhibits sodium and chloride reabsorption in the proximal and distal tubules and the loop of Henle, producing high-degree diuresis independent of carbonic anhydrase inhibition or aldosterone.
