Norepinepherine is a direct acting sympathomimetic amine, identical to the endogenously produced catecolamine norepinepherine. It is an alpha-adrenergic agonist, useful in reversing life-threatening hypotension by increasing systolic and diastolic blood pressure through vasoconstrictive action. It is used to restore blood pressure in toxic insults which create an acute hypotensive state by blocking alpha-adrenergic receptors caused by: dibenyline, dibenamine, phenothiazine derived tranquilizers, copper, ergot alkaloids (Ergotamine, Ethchlorvynol), Amanita (Amanitia spp), yew (Taxus spp), quinine sulfate, Parazosin HCL, lilly-of-the-valley (Convallaria spp), periwinkle (Vinca spp), tricyclic antidepressants, phenoxybenzamine, phentolamine, and terazosin.
