Frumil is a combination medication primarily used in the management of fluid retention (edema) and high blood pressure (hypertension). It contains two active ingredients: amiloride hydrochloride, a potassium-sparing diuretic, and furosemide, a loop diuretic. These components work synergistically to prevent the body from absorbing too much salt, allowing the salt to instead be passed in the urine. While furosemide increases the amount of urine produced, thereby removing excess fluid from the body, amiloride helps maintain the potassium levels in the body, preventing them from getting too low. This balance is crucial for patients who are at risk of hypokalemia (low potassium levels) when taking diuretics. Frumil is often prescribed when other medications have not been effective in controlling blood pressure and fluid retention. It is important for patients taking Frumil to have their kidney function and electrolyte levels monitored regularly.
