Beta2-adrenergic agonists, also known as adrenergic β2 receptor agonists, are a class of drugs that act on the β 2 adrenergic receptor. Like other β adrenergic agonists, they cause smooth muscle relaxation. β 2 adrenergic agonists' effects on smooth muscle cause dilation of bronchial passages, vasodilation in muscle and liver, relaxation of ...

[38] Combined α 1 and beta blockers like labetalol and carvedilol may be more favorable for such purposes due to the possibility of "unopposed α ...
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. [37] Metoprolol exerts its effects by blocking the action of certain neurotransmitters, specifically adrenaline and noradrenaline.
Nebivolol is a beta blocker used to treat high blood pressure and heart failure. [5] As with other β-blockers, it is generally a less preferred treatment for high blood pressure.
