Question

The main function of nor-adrenaline is

• A. Contraction of arteries
• B. To stop contraction of arteries
• C. Relaxation
• D. None of the above

Answer 1

Answer: (A)

Contraction of arteries

Norepinephrine or noradrenaline is used for hypotension as a vasopressor medication for patients with critical hypotension. It is given intravenously and acts on adrenergic receptors to cause vasoconstriction. Its effects are to increase blood pressure through agonist activity on receptors and cause a resultant increase in peripheral vascular resistance.

So, the correct answer is option A.
