For example, vasoconstriction is a hypothermic preventative in which the blood vessels constrict and blood must move at a higher pressure to actively prevent a hypoxic reaction. ATP is used as a form of energy to increase this pressure to heat the body. Once homeostasis is restored, the blood pressure and ATP production regulates.
A nitrovasodilator is a pharmaceutical agent that causes vasodilation (widening of blood vessels) by donation of nitric oxide (NO), [1] and is mostly used for the treatment and prevention of angina pectoris. This group of drugs includes nitrates (esters of nitric acid), which are reduced to NO in the body, as well as some other substances.
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 ...
Ace Inhibitors, which block the formation of Angiotensin II, a chemical that causes blood vessels to constrict. "By blocking this chemical, the blood vessels dilate, causing lower pressure," Dr ...
As a stimulant, Adderall can constrict blood vessels throughout the body. As a result, it can restrict the flow of blood to the reproductive organs and make it more difficult to achieve and ...
The medication is designed to constrict blood vessels, explains Jamie Alan, Ph.D., an associate professor of pharmacology and toxicology at Michigan State University. “In congestion, this will ...
It causes more dilation in the arterioles and precapillary vessels than the postcapillary vessels and venules. The increased dilation allows for more blood, which is unable to push through to the relatively constricted postcapillary venules and vessels; the pressure causes much of the plasma to move into the interstitial space.

Bradykinin (BK) (from Greek brady-'slow' + -kinin, kīn(eîn) 'to move') is a peptide that promotes inflammation.It causes arterioles to dilate (enlarge) via the release of prostacyclin, nitric oxide, and endothelium-derived hyperpolarizing factor and makes veins constrict, via prostaglandin F2, thereby leading to leakage into capillary beds, due to the increased pressure in the capillaries.
