🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine combines two diuretics with complementary mechanisms. Furosemide inhibits the sodium-potassium-chloride cotransporter in the thick ascending limb of the loop of Henle, leading to increased excretion of sodium, chloride, and water. Spironolactone is a competitive antagonist of aldosterone at the mineralocorticoid receptor in the distal tubule and collecting duct, reducing sodium reabsorption and potassium excretion. Together, they produce a synergistic diuretic effect while spironolactone helps mitigate furosemide-induced potassium loss.
Mechanism Steps
💡 How to Take lasidac forte 40mg/25mg tablet
Strength: Each tablet contains furosemide 40 mg and spironolactone 25 mg.
Dosage Information
| Adult Dosage | The usual adult dose of this medicine is one tablet (furosemide 40 mg + spironolactone 25 mg) taken orally once daily, preferably in the morning. However, the dose may be adjusted by your doctor based on your condition, response to treatment, and renal function. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function. Do not self-adjust the dose. |
| Pediatric Dosage | Pediatric dosing is not established from available information. Consult a pediatrician. |
| Elderly Dosage | Elderly patients may be more sensitive to the effects of this medicine, especially dehydration and electrolyte imbalances. Start with a lower dose and monitor closely. Dose must be individualized by a qualified clinician. |
| Renal Impairment | Use with caution in patients with renal impairment. Dose adjustment may be necessary based on creatinine clearance. Monitor renal function closely. In severe renal impairment, this combination may be contraindicated. |
| Hepatic Impairment | Use with caution in patients with hepatic impairment. Furosemide can precipitate hepatic coma in cirrhosis. Spironolactone is metabolized in the liver; dose adjustment may be needed. Monitor liver function. |
| Maximum Daily Dose | The maximum daily dose should not exceed what is prescribed by your doctor. Typically, the maximum recommended dose of furosemide is 600 mg/day and spironolactone is 400 mg/day, but in this fixed combination, the dose is limited by the tablet strength. Do not exceed the prescribed dose. |
