Question

Quizplus · Accepted Answer

The vasoconstrictive effects of alpha₁-adrenergic agonists, such as epinephrine, help delay absorption of a local anesthetic, prolonging the anesthetic's effects. These agents can increase blood pressure but are not the primary drugs used except in emergency situations. Alpha₁ receptors in the radial muscles of the iris, not vasoconstriction, cause mydriasis. Reflex bradycardia is a side effect and not a clinical use of these agents.
