Indications
Frusemide & Spironolactone combination is indicated in-
Essential hypertension
Chronic congestive heart failure
Hepatic cirrhosis, with collection of fluid in the abdominal cavity (ascites)
Swelling due to excess fluid retention (edema)

Resistant edema associated with secondary hyperaldosteronism
Therapeutic Class
Potassium-sparing diuretics, Potassium-sparing diuretics & Aldosterone antagonists
Pharmacology
Spironolactone (potassium sparing diuretic) and Furosemide (loop diuretic) have different but complementary mechanisms and sites of action. Therefore, when given together they produce additive or synergistic diuretic. The Furosemide component inhibits the Na+/K+/2Cl- co-transporter in the ascending Loop of Henle and blocks the reabsorption of sodium, potassium and chloride ions; thereby increasing the quantity of sodium and the volume of water excreted in the urine. This characteristically induces potassium loss. The spironolactone component inhibits the reabsorption of sodium in exchange for potassium at the distal tubule by antagonising the action of aldosterone so that sodium excretion is greatly favoured and the excess loss of potassium, induced by the Furosemide, is reduced
Dosage & Administration
Furosemide 20 and spironolactone 50 mg: 1 to 4 tablets daily according to the patient’s response.

Furosemide 40 and spironolactone 50 mg: For previously stabilized patients 1 to 2 tablets daily, orally.

Side Effects
Spironolactone may give rise to headache and drowsiness and gastrointestinal distress, including cramp and diarrhoea. Ataxia, mental confusion, and skin rashes have been reported as side effect. Gynaecomastia is not uncommon and in rare cases breast enlargement may persist. Other endocrine disorders including hirsutism, deepening of the voice, menstrual irregularities and impotence. Transient increase in blood-urea-nitrogen concentrations may occur and mild acidosis has been reported. Spironolactone may cause hyponatremia and hyperkalemia. Excessive diuresis may result in dehydration and reduction in blood volume with circulatory collapse with the possibility of vascular thrombosis and embolism particularly in elderly patients. Serious depletion of potassium and magnesium may lead to cardiac arrhythmias.
