Norepinephrine Bitartrate in Sodium Chloride Injection contains the active pharmaceutical ingredient norepinephrine, a catecholamine, in the form of bitartrate salt (monohydrate). Norepinephrine is sometimes referred to as l-arterenol/Levarterenol or l-norepinephrine which differs from epinephrine by the absence of a methyl group on the nitrogen atom. The chemical name for norepinephrine bitartrate (monohydrate) is (-)-α-(aminomethyl)-3,4-dihydroxybenzyl alcohol tartrate (1:1) (salt) monohydrate (molecular weight 337.3 g/mol) and has the following structural formula: Norepinephrine bitartrate (monohydrate) is sparingly soluble in water, very slightly soluble in alcohol and ether, and readily soluble in acids. Norepinephrine Bitartrate in 0.9% Sodium Chloride Injection is supplied as a sterile aqueous ready-to-use solution in 250 mL transparent intravenous bags. Each mL contains 32 mcg, 64 mcg, 128 mcg or 256 mcg of norepinephrine bitartrate monohydrate, equivalent to 16 mcg, 32 mcg, 64 mcg or 128 mcg of norepinephrine base, respectively. Each mL also contains 9 mg of Sodium Chloride USP as a tonicity agent, and may contain Hydrochloric Acid NF and Sodium Hydroxide NF as pH adjusters, for a pH range of 3.4 to 4.0, in Water for Injection. structural formula
