What is the mechanism of action of vasodilators?
Mechanism of Action In general, Vasodilators dilate or prevent constriction of the blood vessels, which allow greater blood flow to various organs in the body. [3] Many vasodilators bind to receptors on endothelial cells of the blood vessel, which stimulate calcium release.
What is an antihypertensive vasodilator?
Antihypertensive vasodilators share the capability of producing vasodilation of arterioles. In addition, two of them, i.e. nitroprussiate and prazosine, also produce vasodilation of veinulae. Both of these agents cause a simultaneous decrease in pre-load and post-load, and may be used in heart failure.
What are the vasodilator drugs?

When are vasodilators used?
This class of drugs is often used to treat cardiovascular conditions, such as hypertension. Vasodilators are a group of medicines that dilate (open) blood vessels, which allows blood to flow more easily. They’re used to treat or prevent: High blood pressure (hypertension)
How are vasodilators administered?
The most commonly used vasodilators are nitroprusside, nitroglycerin, and hydralazine. Nitroprusside and nitroglycerin, which have a fast onset and short duration of action, should be administered as continuous intravenous infusions.
What is the action of balanced vasodilators?
Most vasodilator drugs are mixed (or balanced) vasodilators in that they dilate both arteries and veins and therefore can have wide application in hypertension, heart failure and angina.
What is the direct-acting vasodilators?
Direct-acting vasodilators are a class of antihypertensive medications that are used for severe refractory hypertension, malignant hypertension, and hypertensive emergencies.
How do vasodilators affect cardiac output?
Vasodilators can lead to renal retention of sodium and water, which increases blood volume and cardiac output and thereby compensates for the reduced systemic vascular resistance.
What is a natural vasodilator?
Leafy Greens Leafy greens like spinach and collard greens are high in nitrates, which your body converts into nitric oxide, a potent vasodilator. Eating nitrate-rich foods may help improve circulation by dilating blood vessels, allowing your blood to flow more easily.
Is aspirin a vasodilator?
Aims. Compared with other non-steroid anti-inflammatory drugs (NSAIDs), aspirin is not correlated to hypertension. It has been shown that aspirin has unique vasodilator action in vivo, offering an explanation for the unique blood pressure effect of aspirin.
