Resitone Tablet 40 mg + 50 mg is a combination diuretic therapy containing Furosemide 40 mg and Spironolactone 50 mg. This formulation is designed to promote effective fluid balance and is primarily used for conditions associated with edema and fluid overload, such as heart failure, liver cirrhosis, and kidney disorders. By combining a loop diuretic (Furosemide) with a potassium-sparing diuretic (Spironolactone), Resitone provides synergistic diuretic effects while reducing the risk of hypokalemia, a common side effect of loop diuretics.

Indications

Resitone 40 mg + 50 mg is indicated for:

• Edema associated with congestive heart failure, liver cirrhosis, or nephrotic syndrome.

• Hypertension where fluid reduction is clinically indicated.

• Ascites management in patients with liver disease.

• Combination therapy in patients requiring enhanced diuretic effect while maintaining potassium balance.

Therapeutic Class

Diuretic Combination: Loop Diuretic + Potassium-Sparing Diuretic

Pharmacology

• Furosemide is a potent loop diuretic that inhibits sodium and chloride reabsorption in the ascending loop of Henle, leading to increased urine output and reduced extracellular fluid volume. It acts rapidly and is effective in mobilizing excess fluid in edema and hypertension.

• Spironolactone is a potassium-sparing diuretic and aldosterone antagonist that inhibits sodium reabsorption in the distal tubules while conserving potassium and hydrogen ions. By antagonizing aldosterone, it also reduces myocardial fibrosis and improves outcomes in heart failure patients.

• The combination enhances diuresis while mitigating potassium loss, providing a balanced and safer fluid management approach.

Dosage and Administration

• The dose of Resitone Tablet is individualized based on patient condition, severity of edema, and renal function.

• Typical starting dose: 1 tablet once daily or as prescribed by a physician.

• The dose may be adjusted according to clinical response, urine output, and electrolyte levels.

• Tablets should be taken with water, preferably in the morning to avoid nocturia.

• Close monitoring of serum electrolytes, particularly potassium, sodium, and renal function, is recommended during therapy.

Drug Interactions

• Concomitant use with ACE inhibitors, ARBs, or potassium supplements may increase the risk of hyperkalemia.

• Use with NSAIDs may reduce diuretic efficacy and increase the risk of renal impairment.

• Care should be taken when co-administered with other antihypertensives, digoxin, or lithium due to potential electrolyte disturbances.

Contraindications

• Known hypersensitivity to Furosemide, Spironolactone, or any component of the formulation.

• Severe renal insufficiency or anuria.

• Hyperkalemia or conditions predisposing to high potassium levels.

• Addison’s disease or other disorders associated with mineralocorticoid deficiency.

Side Effects

Common side effects may include:

• Electrolyte disturbances (hypokalemia, hyperkalemia, hyponatremia)

• Dizziness, hypotension, or lightheadedness

• Gastrointestinal symptoms: nausea, vomiting, diarrhea

• Headache and fatigue

• Rare effects: gynecomastia or menstrual irregularities due to Spironolactone

Monitoring and dose adjustment help reduce the risk of adverse effects.

Precautions and Warnings

• Regular monitoring of blood pressure, renal function, and electrolytes is recommended.

• Use with caution in hepatic impairment, diabetes, or gout.

• Avoid excessive sunlight exposure as loop diuretics may cause photosensitivity.

• Patients should maintain adequate fluid intake to prevent dehydration.

Pregnancy and Lactation

• Use only if clearly necessary; safety in pregnancy has not been fully established.

• Furosemide and Spironolactone can cross the placenta.

• Lactating mothers should avoid use or monitor infants for adverse effects, as both drugs may be excreted in breast milk.

Storage Conditions

Store in a cool, dry place below 30°C, protected from light and moisture. Keep out of reach of children.

Mode of Action

Resitone Tablet 40 mg + 50 mg combines the rapid and potent diuretic effect of Furosemide with the potassium-conserving properties of Spironolactone. Furosemide promotes sodium, chloride, and water excretion from the loop of Henle, while Spironolactone blocks aldosterone-mediated sodium reabsorption in distal renal tubules. This dual action provides effective fluid removal, reduces edema, and maintains electrolyte balance, supporting cardiovascular and renal health in patients with fluid overload.
