Quizplus · Accepted Answer

The vasoconstrictive effects of alpha₁-adrenergic agonists, such as epinephrine, help produce hemostasis in skin and mucous membranes. 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.
