Continuous labetalol use further decreases peripheral vascular resistance. However, during exercise, cardiac output remains the same due to a compensatory mechanism that increases 1639:
Labetalol was the first drug created that combined both α- and β-adrenergic receptor blocking properties. It was created to potentially fix the compensatory reflex issue that occurred when blocking a single receptor subtype, i.e. vasoconstriction after blocking β-adrenergic receptors or tachycardia

without intrinsic activity, and is, therefore, an antagonist. Labetalol, with its 1-methyl-3-phenylpropyl substituted amine, is greater in size relative to a t-butyl group and therefore acts predominantly as an antagonist. The overall structure of labetalol is very polar. This was created by

after blocking α-adrenergic receptors. Because the reflex from blocking the single receptor subtypes acted to prevent the lowering of blood pressure, it was postulated that weak blocking of both α- and β-adrenergic receptors could work together to decrease blood pressure.

more favorable for such purposes. The rate of unopposed α-stimulation with selective beta blockers has been reported to be 0.4%, whereas no cases of unopposed α-stimulation have been reported with dual alpha and beta blockers like labetalol.

including rats, rabbits, and dogs, was found to cross into the brain in negligible amounts, probably for reasons other than low lipophilicity. On the other hand, the drug has been shown to cross the blood–placenta barrier in humans.
