View Test Prep - vasodilator chart from NU 2810 at Milwaukee School of Engineering. Vasodilators are useful in the management of hypertension, angina, heart failure, myocardial infarction, and more. 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. Vasodilator Drugs. They are commonly used to treat high blood pressure, heart conditions like heart failure and angina, and pulmonary hypertension. Indirectly acting vasodilators : 1.Drugs that interfere with the sympathetic nervous system 1-blockers (Phentolamine, Phenoxybenzamine).

Calcium channel blockers as a class are considered vasodilators, but individual agents have different relative potencies and additional effects. drug classification. 2 agonists ( clonidine) D1 receptor agonist : Fenoldopam. There is a potential for increased risk of bleeding, particularly in . Vasodilators are highly effective antihypertensive agents that dominated the management of hypertension in the 1950s and 1960s. Test. Labetalol's actions at alpha-1 and beta-receptors lead to vasodilation and decreased total peripheral resistance, which results in decreased blood pressure without a substantial decrease in resting heart rate, cardiac output, or stroke volume. They produce reflex sympathomimetic action resulting in increased cardiac output, heart rate and renin secretion. Central and Peripheral Inhibitors: i.

Generally all drugs in this class improve cardiac contraction by increasing intracellular calcium concentration via various mechanisms; The smooth muscles of blood vessels is responsible for arteriolar and venous tone which in turn play important role role in myocardial wall stress. ACE Inhibitors (Angiotensin-Converting Enzyme Inhibitors (ACEIs)) Example: Ramipril, Lisinopril, Perindopril. Vasodilators do differ with respect to their potential effects on the myocardium, which may have important implications in the failing myocardium. As a result, blood flows more easily through the vessels. Vasodilators are medicines that dilate (widen) blood vessels, allowing blood to flow more easily through. 2.Drugs that block the renin-angiotensin system: - Renin inhibitors ( aliskiren) - ACE inhibitors (ramipril) - AT1 receptor antagonists .
