Not to be confused with Metaxalone a muscle relaxant.Metolazone is a thiazide-like diuretic marketed under the brand names Zytanix from Zydus Cadila Zaroxolyn and Mykrox. It is primarily used to treat congestive heart failure and high blood pressure. Metolazone indirectly decreases the amount of water reabsorbed into the bloodstream by the kidney so that blood volume decreases and urine volume increases. This lowers blood pressure and prevents excess fluid accumulation in heart failure.
