Metabolite Identification
Common NameHydralazine pyruvate hydrazone
DescriptionHydralazine pyruvate hydrazone is a metabolite of hydralazine. Hydralazine (apresoline) is a direct-acting smooth muscle relaxant used to treat hypertension by acting as a vasodilator primarily in arteries and arterioles. By relaxing vascular smooth muscle, vasodilators act to decrease peripheral resistance, thereby lowering blood pressure and decreasing afterload. (Wikipedia)
