Answer

Beta Blockers, Beta1 Selective

Atenolol (Tenormin)

Atenolol selectively blocks beta1 (cardioselective) receptors, with little or no effect on beta2 types. After primary treatment with an alpha receptor blocker, atenolol may be used as adjunctive therapy if control of tachycardia becomes necessary before or during surgery.

Metoprolol (Lopressor)

Metoprolol selectively blocks beta1 (cardioselective) receptors, with little or no effect on beta2 types at low doses. However, at higher plasma concentrations, metoprolol also inhibits beta2 receptors. After primary treatment with an alpha receptor blocker, metoprolol may be used as adjunctive therapy if control of tachycardia becomes necessary before or during surgery.

Esmolol (Brevibloc)

Esmolol is a short-acting beta1 selective beta blocker administered via continuous intravenous infusion. In low doses, esmolol selectively blocks sympathetic stimulation mediated by beta1-adrenergic receptors in the heart and vascular smooth muscle. Esmolol's extremely short duration of action makes the drug useful for acute control of hypertension or certain supraventricular arrhythmias.
