Acute vasodilator therapy is directed at more urgent clinical conditions; most commonly characterized by cardiogenic dyspnea from high left ventricular end-diastolic pressure, resulting in elevated pulmonary capillary wedge pressure and varying degrees of pulmonary edema and congestion. There are several classifications of vasodilator drugs. A non diuretic benzothiadiazine indicated . 1. Differences between drugs within the class Refer to the discussion on hydralazine, a primary afterload-reducing agent, and nitrates, primarily preload-reducers. Vasodilators Diuretics Diuretics help the body get rid of excess sodium (salt) and water and help control blood pressure. With the advent of newer and better-tolerated antihypertensive agents, their use has declined dramatically. Drugs may act directly on the smooth muscle cells, or they may act indirectlyfor example, by altering the activity of nerves of the autonomic nervous system that regulate vasoconstriction or vasodilation. baroreceptors . They affect the muscles in the walls of the arteries and veins, preventing the muscles from tightening and the walls from narrowing. They produce reflex sympathomimetic action resulting in increased cardiac output, heart rate and renin secretion. Properties and uses: It is a white or almost white crystalline powder, which is slightly soluble in methylene chloride, but soluble in water and slightly soluble in alcohol. Learn.
