    Product Description

    (±)-Norepinephrine is a racemic mixture of the endogenous neurotransmitter (–)-norepinephrine (Item No. 16673) and (+)-norepinephrine. It induces cAMP accumulation in rat cerebral cortical membranes when used at concentrations ranging from 1 to 100 µM.1 (±)-Norepinephrine induces contraction of bovine anterior cerebral, middle cerebral, and internal carotid arterial strips (EC50s = 0.91, 0.92, and 0.87 µM, respectively) but induces relaxation of bovine posterior cerebral arterial strips (EC50 = 0.95 µM).2 Formulations containing (±)-norepinephrine have been used for the restoration of blood pressure in acute hypotensive states.

    WARNING This product is not for human or veterinary use.
