Ethacrynic Acid is a diuretic medication primarily used to treat conditions like edema and hypertension. It works by promoting the excretion of sodium and water from the body, which helps reduce fluid buildup and lower blood pressure. This medication is often prescribed when other diuretics, such as thiazides, are not effective or suitable for a patient. It is important to monitor kidney function and electrolyte levels while using Ethacrynic Acid, as it can lead to imbalances if not managed properly.
