Question

Quizplus · Accepted Answer

Beta-adrenergic blocking agents (such as atenolol) work by selectively blocking beta-1 adrenergic receptors in the heart, which decreases the heart rate and reduces the contractility of the heart. This results in a decrease in blood pressure and workload on the heart. It does not directly affect vascular muscle action, vasoconstriction, or the action of aldosterone. Beta-adrenergic blocking agents, such as atenolol, block the beta-adrenergic receptors in the heart, which decreases heart rate and cardiac output. This can be helpful in conditions such as hypertension or heart failure where the heart is overworking and needs to be slowed down. Blocking vascular muscle action and reducing vasoconstriction are actions more commonly associated with other types of antihypertensive medications such as calcium channel blockers or ACE inhibitors. Suppressing the action of aldosterone is seen with aldosterone antagonists such as spironolactone, which are used in conditions such as heart failure or resistant hypertension.
