Question

Quizplus · Accepted Answer

Potent beta-1 effects primarily stimulate the beta-1 receptors in the heart, leading to increased heart rate and contractility. Smooth muscle relaxation and peripheral vasodilation are more associated with drugs that stimulate beta-2 receptors, while peripheral vasoconstriction is more associated with drugs that stimulate alpha receptors.
