“Labetalol is a beta blocker, or an antagonist of the β-adrenergic receptors. It is specifically a non-selective antagonist of the β1- and β2-adrenergic receptors. Labetalol has intrinsic sympathomimetic activity. It is also an antagonist of the α1-adrenergic receptor, and hence is additionally an alpha blocker. The antagonism of the adrenergic receptors by labetalol is competitive against other catecholamines and its actions on the receptors are potent and reversible. Labetalol acts by blocking α- and β-adrenergic receptors, resulting in decreased peripheral vascular resistance without significant alteration of heart rate or cardiac output.”
