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.
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.

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 ...
The classification of drugs have been around since 1964 ... are only available in intravenous forms and can expand blood vessels. ... Churchwell said they can cause bronchial constriction, which ...
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 ...
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 ...
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 standard drug treatment of dexamethasone does not alter the hypoxia or the consequent vasoconstriction, but stimulates fluid reabsorption in the lungs to reverse the edema. Additionally, several studies on native populations remaining at high altitudes have demonstrated to varying degrees the blunting of the HPV response.
