What is the primary action of Frusemide?

Frusemide, commonly known as furosemide, primarily functions as a loop diuretic, and its main action is the inhibition of renal sodium reabsorption. It targets the sodium-potassium-chloride (Na-K-2Cl) co-transporter found in the ascending limb of the Loop of Henle in the kidneys. By disrupting this transport mechanism, Frusemide prevents the reabsorption of sodium, chloride, and water, resulting in increased urine production and the excretion of these electrolytes.

This mechanism is crucial in clinical practice, particularly for conditions such as heart failure, hypertension, and renal disorders, where excess fluid retention can be problematic. The increased diuresis helps to reduce fluid overload, decrease blood pressure, and improve symptoms related to congestion.

The other options do not accurately describe the primary action of Frusemide. While potassium levels may be affected due to increased urinary excretion, the drug does not promote potassium retention; in fact, it can lead to hypokalemia. Additionally, instead of decreasing urine output, Frusemide actually increases urinary excretion. Lastly, there is no significant role of Frusemide in the stimulation of liver glycogen conversion.
