Metoprolol is a beta blocker, or an antagonist of the β-adrenergic receptors. It is specifically a selective antagonist of the β 1-adrenergic receptor and has no intrinsic sympathomimetic activity. Metoprolol exerts its effects by blocking the action of certain neurotransmitters, specifically adrenaline and noradrenaline.
Highly lipophilic beta blockers include penbutolol, pindolol, propranolol, and timolol, moderately lipophilic beta blockers include acebutolol, betaxolol, bisoprolol, carvedilol, metoprolol, and nebivolol, and low lipophilicity or hydrophilic beta blockers include atenolol, carteolol, esmolol, labetalol, nadolol, and sotalol.
The progress in β-blocker development led to the introduction of drugs with variety of properties. β-blockers were developed having a relative selectivity for cardiac β1-receptors (for example metoprolol and atenolol), partial adrenergic agonist activity , concomitant α-adrenergic blocking activity (for example labetalol and carvedilol) and ...

The combination of beta blockers and antihypertensive drugs will work on different mechanism to lower blood pressure. For example, the co-administration of beta-1 blocker atenolol and ACE inhibitor lisinopril could produce a 50% larger reduction in blood pressure than using either drug alone. Hypertensive drugs

Bisoprolol, sold under the brand name Zebeta among others, is a beta blocker which is selective for the beta-1 receptor and used for cardiovascular diseases, including tachyarrhythmias, high blood pressure, angina, and heart failure. It is taken by mouth.
Atenolol is a beta blocker medication primarily used to treat high blood pressure and heart-associated chest pain. Atenolol, however, does not seem to improve mortality in those with high blood pressure. Other uses include the prevention of migraines and treatment of certain irregular heart beats.
Beta-blockers: Metoprolol; Atenolol; Bisoprolol; Block beta-1 receptors in the heart → stop the effects of catecholamines on the heart→ reduce heart rate, heart contractility and conduction velocity → reduce the workload of the heart: Side effects. Bradycardia; Hypotension; Heart Block; Impaired glucose metabolism
Labetalol is a beta blocker, or an antagonist of the β-adrenergic receptors. It is specifically a non-selective antagonist of the β 1-and β 2-adrenergic receptors. Labetalol has intrinsic sympathomimetic activity. It is also an antagonist of the α 1-adrenergic receptor, and hence is additionally an alpha blocker.
