[R-(R*,S*)]-4-(2-Amino-1-hydroxypropyl)brenzcatechinhydrochlorid

Levonordefrin Hydrochloride is the hydrochloride salt of levonordefrin, a synthetic catecholamine and norepinephrine derivative with sympathomimetic and antihypertensive effects. 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.
