Drug Class and Mechanism Lasix
Furosemide is a potent diuretic (water pill). Furosemide works by blocking the absorption of salt and fluid in the kidney tubules, causing a profound increase in urine output (diuresis). The diuretic effect of furosemide can cause body water and electrolyte depletion. Therefore, careful medical supervision is necessary during treatment.
