Bumetanide
Bumetanide (CAS 28395-03-1) is a potent loop diuretic with the chemical formula C17H20N2O5S and a molecular weight of 364.42 g/mol. It functions by inhibiting the Na+-K+-2Cl- symporter in the thick ascending limb of the loop of Henle. This action leads to increased excretion of water, sodium, chloride, potassium, and other electrolytes. Bumetanide is primarily used to manage edema associated with congestive heart failure, liver disease, and renal disease.
