Etafedrine ({{Abbrlink|INN|International Nonproprietary Name}}, {{Abbrlink|BAN|British Approved Name}}), sold under the brand name Nethaprin among others and also known as N-ethylephedrine, is a sympathomimetic agent used as a bronchodilator to treat asthma.{{cite book | vauthors = Elks J | title=The Dictionary of Drugs: Chemical Data: Chemical Data, Structures and Bibliographies | publisher=Springer US | year=2014 | isbn=978-1-4757-2085-3 | url=https://books.google.com/books?id=0vXTBwAAQBAJ&pg=PA503 | access-date=30 August 2024 | page=503}}{{cite book | vauthors = Morton IK, Hall JM | title=Concise Dictionary of Pharmacological Agents: Properties and Synonyms | publisher=Springer Netherlands | year=2012 | isbn=978-94-011-4439-1 | url=https://books.google.com/books?id=tsjrCAAAQBAJ&pg=PA114 | access-date=30 August 2024 | page=114}}{{cite web | title=Etafedrine: Uses, Interactions, Mechanism of Action | website=DrugBank Online | date=31 December 1983 | url=https://go.drugbank.com/drugs/DB11587 | access-date=30 August 2024}} It was previously commercially available as both the free base and as the hydrochloride salt from Sanofi-Aventis (now Sanofi) but is now no longer marketed.{{Citation needed|date=August 2024}}

Pharmacology

Unlike ephedrine and tyramine, etafedrine does not induce the release of epinephrine or norepinephrine and instead acts as a selective β2-adrenergic receptor agonist, thereby mediating its bronchodilator effects.{{cite journal | vauthors = Lindmar R, Löffelholz K, Stieh-Koch U | title = On the mechanism of bronchodilatation by etafedrine | journal = Arzneimittel-Forschung | volume = 35 | issue = 3 | pages = 602–604 | year = 1985 | pmid = 4039586 }}
