Which antihypertensive drug reduces cardiac output by blocking β₁-adrenergic receptors, thereby decreasing heart rate and contractility?
Show answer and explanation
Correct answer: Bisoprolol
Bisoprolol is a β₁-selective blocker that reduces catecholamine-mediated heart rate and contractility. This lowers cardiac output and blood pressure.
