Levonordefrin's antihypertensive effect is exerted through activation of alpha 2-adrenergic receptors in the cardiovascular control center of the CNS thereby suppressing the sympathetic output from the brain and subsequently lowering blood pressure. Levonordefrin binds to and activates peripheral alpha 2- adrenergic receptors, thereby causing vasoconstriction."}]
