Norfenefrine

(Redirected from M-octopamine)

Norfenefrine, also known as meta-octopamine or norphenylephrine and sold under the brand name Novadral among others, is a sympathomimetic medication which is used in the treatment of hypotension (low blood pressure).[3][4][5][6] Along with its structural isomer p-octopamine and the tyramines, norfenefrine is a naturally occurring endogenous trace amine and plays a role as a minor neurotransmitter in the brain.[7]

Medical uses

edit

Norfenefrine is used in the treatment of hypotension (low blood pressure).[3] It is said to be similarly effective or less effective than midodrine.[8][9][10]

Pharmacology

edit

Pharmacodynamics

edit

Norfenefrine is described as an α-adrenergic receptor agonist and sympathomimetic agent.[4][6] It is said to act predominantly as an α1-adrenergic receptor agonist.[3]

Chemistry

edit

Norfenefrine, also known as 3,β-dihydroxyphenethylamine, is a substituted phenethylamine derivative.[4][6] It is an analogue of norepinephrine (3,4,β-trihydroxyphenethylamine), of meta-tyramine (3-hydroxyphenethylamine), of phenylephrine ((R)-β,3-dihydroxy-N-methylphenethylamine), of etilefrine (3,β-dihydroxy-N-ethylphenethylamine), and of metaterol (3,β-dihydroxy-N-isopropylphenethylamine), as well as of metaraminol ((1R,2S)-3,β-dihydroxy-α-methylphenethylamine).[4]

Norfenefrine is used medically as the hydrochloride salt.[4][6]

The predicted log P of norfenefrine is -0.28 to -0.95.[11][12][13]

Names

edit

Norfenefrine is the generic name of the drug and its INNTooltip International Nonproprietary Name.[4][6] Synonyms of norfenefrine include hydroxyphenylethanolamine, nor-phenylephrine, and m-norsynephrine, among others.[4][6] Brand names of norfenefrine include Novadral, A.S. COR, Coritat, Energona, Hypolind, Norfenefrin Ziethen, and Norfenefrin-Ratiopharm, among others.[6]

Availability

edit

Norfenefrine is marketed in Europe, Japan, and Mexico.[6]
