Exempel på hur man kan använda VASOCONSTRICTORS i en mening

• Topical decongestants are vasoconstrictors, and work by constricting the blood vessels within the nasal cavity.
• Vasodilation and vasoconstriction are complex phenomena; they are functions not merely of the fluid mechanics of pressure and tissue elasticity but also of active homeostatic regulation with hormones and cell signaling, in which the body produces endogenous vasodilators and vasoconstrictors to modify its vessels' compliance.
• Endothelin, and angiotensin are the vasoconstrictors of smooth muscles while nitric oxide and prostacyclin are vasodilators of the smooth muscles.
• A central paradigm holds responsible an excess local pulmonary production of vasoconstrictors that occurs while vasodilatation predominates systemically.
• Endothelial cells regulate vascular tone by producing vasodilators (like nitric oxide and prostacyclin) and vasoconstrictors (like endothelin).
• Relaxin causes vasodilation by an indirect mechanism, where it inhibits the potent vasoconstrictors angiotensin II and endothelin.
• In fact, vasodilators (amylnitrite, carbon dioxide) abolished the aura temporarily or persistently, and vasoconstrictors (norepinephrine, ergotamine tartrate, caffeine) induced the aura.
• With regard to medical and other uses, β-hydroxyamphetamines are employed as sympathomimetics, decongestants, bronchodilators, vasoconstrictors, vasodilators, tocolytics, antitussives, cardiac stimulants, antihypotensive agents, appetite suppressants, psychostimulants, wakefulness-promoting agents, antidepressants, euphoriants or recreational drugs, and performance-enhancing drugs (in exercise and sports), among others.
