alpha adrenergic receptors การใช้

• Carvedilol is both a non-selective alpha adrenergic receptor blocker ( ?1 ).
• Pure beta blockers do not inhibit lid-retraction in the eyes, which is mediated by alpha adrenergic receptors.
• An "'adrenergic alpha-agonist "'( or "'alpha-adrenergic agonists "') are a class sympathomimetic agents that selectively stimulates alpha adrenergic receptors.
• Direct acting sympathomimetic amines, such as phenylephrine stimulate alpha adrenergic receptors, while mixed-acting agents, such as pseudoephedrine can stimulate both alpha and beta adrenergic receptors directly and indirectly by releasing norepinephrine from sympathetic nerve terminals.
