Lasix

Product Overview

Lasix is a diuretic medication containing the active ingredient Furosemide. This potent “water pill” is clinically proven to treat edema (fluid retention) associated with congestive heart failure, liver cirrhosis, and kidney disorders. By enhancing renal excretion of sodium and water, Lasix effectively reduces fluid overload. Available in multiple dosage strengths, these oral tablets provide targeted therapy for fluid management.

Therapeutic Applications

Lasix is indicated for:

• Edema management in congestive heart failure, hepatic cirrhosis, and nephrotic syndrome
• Hypertension treatment (as monotherapy or combination therapy)
• Acute pulmonary edema
• Renal impairment-related fluid retention

Its rapid diuretic action alleviates symptoms including peripheral edema, dyspnea, and abdominal distension while helping regulate blood pressure.

Dosage and Administration Guidelines

Standard Protocol:

• Take orally with or without food as prescribed
• Typical dosing: 20-80 mg daily (adjustable based on response)
• Maximum single dose: 600 mg (hospital settings only)

Important Notes:

• Morning administration recommended to prevent nocturia
• Dose titration based on renal function
• Never discontinue abruptly without medical supervision

Mechanism of Action

As a loop diuretic, Lasix exerts its pharmacological effects by:

1. Inhibiting the Na-K-2Cl symporter in the ascending limb of Henle’s loop
2. Increasing excretion of sodium, chloride, and water
3. Promoting diuresis within 60 minutes (oral) or 5 minutes (IV)
4. Reducing plasma volume and cardiac preload
