|Therap.Cat :||Labetalol is a salicylamide derivative that is a non-cardioselective blocker of Beta-Adrenergic receptors and Alpha-1 Adrenergic Receptors.|
Labetalol is a beta-Adrenergic Blocker. The mechanism of action of labetalol is as an Adrenergic beta-Antagonist.
Labetalol is a third generation selective alpha-1-adrenergic antagonist and non-selective beta-adrenergic antagonist with vasodilatory and antihypertensive properties. Labetalol competitively binds to alpha-1-adrenergic receptors in vascular smooth muscle, thereby inhibiting the adrenergic stimulation of endothelial cell function and vasoconstriction in peripheral blood vessels.
