Vasodilators are medicines that dilate (open) your blood vessels. Vasodilators keep your arteries and veins from narrowing or contracting (squeezing) shut. You have two main types of blood vessels. Veins carry blood to your heart, while arteries carry blood from your heart to the rest of your body.
Vasodilation is blood vessel widening (or getting bigger). It occurs when the muscles in your blood vessel walls relax. When you take a vasodilator, the blood vessel’s middle interior (lumen) is the part that widens.
There are several types of vasodilator medications, and they all work slightly differently. Direct vasodilators directly affect the muscle cells that line your blood vessels. They make your muscle cells relax so that blood vessels open. Because they work quickly, they can cause more side effects. Healthcare providers use direct vasodilators when ot...
Types of vasodilators include: 1. Angiotensin-converting enzyme (ACE) inhibitorsdecrease ACE enzymes. Decreasing ACE enzymes lowers angiotensin. Angiotensin is a chemical that causes blood vessel constriction (narrowing). ACE inhibitors are direct vasodilators. 2. Angiotensin receptor blockers (ARBs) keep angiotensin from attaching to your blood ve...
Healthcare providers may prescribe vasodilators to treat conditions that affect blood flow, including: 1. Angina(chest pain caused by decreased blood flow). 2. Congestive heart failure (CHF). 3. High blood pressure (hypertension). 4. Preeclampsia(hypertension during pregnancy). 5. Postpartum preeclampsia(hypertension after childbirth). 6. Pulmonary...
There are many vasodilator drugs. Your provider will recommend a medication that is right for you, depending on the underlying condition. You may need to try several types to find the right one. A list of common vasodilators includes: 1. ACE inhibitors such as benazepril (Lotensin®) or lisinopril (Prinivil®, Zestril®). 2. ARBs such as losartan (Coz...
Vasodilators can be very effective for people with certain heart conditions. They are widely used treatments for high blood pressure. Opening your blood vessels can: 1. Improve blood flow through your heart. 2. Reduce pressure in your blood vessels or on your heart. 3. Send more oxygen to your heart.
Direct vasodilators are strong medicines. Typically, healthcare providers only prescribe them when other treatments have failed to control symptoms. Direct vasodilators may cause more severe side effects than other types of vasodilators. Sometimes, these side effects are severe enough that you need other medicines to treat the side effects. For exa...
Vasodilators are not the only way to open blood vessels. Some other factors that cause vasodilation include: 1. Exercise:When you exercise, your blood vessels open so that your muscles can get extra nutrients and oxygen. 2. Inflammation: Inflammationis part of your body’s process of repairing the damage. When a part of your body is inflamed, your b...
Ask your provider about possible food or drug interactions if you are taking vasodilators. It’s important to be honest and thorough when telling your provider what medications or supplements you take. Some vasodilator interactions to watch for include: 1. ACE inhibitors and potassium supplements. 2. ACE inhibitors and medications with lithium. 3. A...

Aug 9, 2023 · Vasodilators are medicines that open, also called dilate, blood vessels. Vasodilators affect the muscles in the walls of the arteries and veins. They prevent the muscles from tightening and the walls from narrowing. As a result, blood flows more easily through the vessels. The heart doesn't have to pump as hard.
Sep 18, 2023 · Vasodilators are an important class of medications that lower blood pressure and improve blood flow by relaxing the muscles in blood vessel walls. They are commonly used to treat high blood pressure, heart conditions like heart failure and angina, and pulmonary hypertension. Common side effects of vasodilators include dizziness and headache.
Vasoconstrictor medications include agonists of vasopressin, agonists of the alpha-adrenoceptor (the receptor for adrenaline), adrenaline and noradrenaline , dopamine, dobutamine, phenylephrine. In the context of maxillofacial surgery, vasoconstricting agents have various uses. Vasoconstriction is a means of stopping bleeding, for example a ...

Because vasoconstrictor drugs increase arterial pressure, they comprise a functional group of drugs known as pressor drugs. Hypotension , which is a systolic pressure of less than 90 mmHg or a diastolic pressure less than 60 mmHg, needs to be aggressively treated because blood flow to critical organs, particularly the brain, heart and kidneys may become compromised to an extent that organ ...
