How Frusemide works
Furosemide(Frusemide) is a potent diuretic medication.
It works by inhibiting the reabsorption of sodium and chloride ions in a specific part of the kidneys known as the ascending loop of Henle and the distal renal tubule.
By blocking these ions from going back into your bloodstream, Furosemide helps to increase the amount of urine produced by your kidneys.
This process helps to reduce the amount of fluid in your blood, which in turn decreases the workload on your heart.
