Question

Quizplus · Accepted Answer

Beta-adrenergic blocking medications, also called beta-blockers, work by blocking the beta-receptors for epinephrine and norepinephrine. This decreases the effects of these neurotransmitters on the heart and blood vessels, leading to decreased heart rate, decreased blood pressure, and decreased workload on the heart. Beta-blockers do not increase heart rate, stroke volume, or inhibit the actions of acetylcholine.
