/ˌnɔrɛpəˈnɛfr(ə)n/

Origin: Formed within English, by derivation. Etymons: nor- prefix, epinephrine n.

Etymology: < nor- prefix + epinephrine n.

Biochemistry.

A compound structurally related to epinephrine (adrenaline), which functions as a neurotransmitter in the central and peripheral sympathetic nervous systems and is also a secretory product of the adrenal medulla, and is used as a vasoconstricting drug; 1-(3, 4-dihydroxyphenyl)-2-aminoethanol, (HO)₂C₆H₃·CHOH·CH₂NH₂. Also called noradrenaline.Norepinephrine is the Recommended International Nonproprietary Name (rINN) of this compound.
