By increasing cAMP levels, these medications cause the smooth muscles to relax. [34] This relaxation has a significant benefit in our blood vessels as it leads to vasodilation, which means the blood vessels widen. [34] [35] Vasodilation helps to reduce resistance against blood flow, allowing for better circulation throughout the body. [36]
Sildenafil’s ability to increase blood flow makes the medication useful for managing other conditions. ... Normally, the pulmonary artery supplies oxygen-filled blood from the lungs to the heart ...
An antihypotensive, also known as vasopressor, is an agent that raises blood pressure by constricting blood vessels, thereby increasing systemic vascular resistance. This is different from inotropes which increase the force of cardiac contraction. Some substances do both (e.g. dopamine, dobutamine).
Medications causing vasoconstriction, also known as vasoconstrictors, are one type of medicine used to raise blood pressure. Generalized vasoconstriction usually results in an increase in systemic blood pressure, but it may also occur in specific tissues, causing a localized reduction in blood flow.
Cardiovascular agents are drugs that affect the rate and intensity of cardiac contraction, blood vessel diameters, blood volume, blood clotting and blood cholesterol levels. [1] They are indicated to treat diseases related to the heart or the vascular system (blood vessels), such as hypertension , hyperlipidemia , coagulation disorders , heart ...
[1] [2] They are used to improve blood flow in people with cerebrovascular insufficiency and to treat neurological disorders secondary to this condition. [2] A number of different cerebral vasodilators exist. [2] [1] [3] An example is ifenprodil, which has been marketed for use as a cerebral vasodilator in France, Hong Kong, and Japan.
