What is the generic name for the brand name Lasix?

The brand name Lasix corresponds to the generic name furosemide. Furosemide is a potent diuretic that is commonly used to treat conditions such as heart failure, edema, and hypertension by promoting the excretion of fluid and sodium through urine. Its mechanism of action involves inhibiting the reabsorption of sodium and chloride in the loop of Henle in the kidneys, leading to increased urine production and decreased fluid retention.

Understanding the classification of diuretics can help clarify why furosemide is the correct answer. While other options listed are also diuretics, they belong to different classes (e.g., hydrochlorothiazide is a thiazide diuretic, bumetanide is another loop diuretic, and spironolactone is a potassium-sparing diuretic). Each has distinct uses, indications, and side effects, which are important for differentiating among them, but furosemide is definitively identified as the generic name for Lasix.
