Metolazone

Metolazone is a thiazide-like diuretic. It inhibits the Na+/Cl- cotransporter (IC50 = 0.3 µM for the rat transporter) and human carbonic anhydrase VII (CAVII), CAXII, and CAXIII (Kis = 2.1, 5.4, and 15 nM, respectively). Metolazone (0.3 and 1 mg/kg) induces fluid loss and enhances captopril-induced decreases in blood pressure in spontaneously hypertensive rats. Formulations containing metolazone have been used in the treatment of high blood pressure.Formal Name: 7-chloro-1,2,3,4-tetrahydro-2-methyl-3-(2-methylphenyl)-4-oxo-6-quinazolinesulfonamide.
