'''Nalorphine''' (], also known as '''''N''-allyl-normorphine''') trade names Lethidrone and Nalline. Nalorphine acts at two opioid receptors, at the mu receptor it has antagonistic effects and at the kappa receptors it exerts agonistic characteristics. It is used to reverse opioid overdose and (starting in the 1950s) in a challenge test to determine opioid dependence.<ref>[http://www.time.com/time/magazine/article/0,9171,808859,00.html

Nalorphine was the second opioid antagonist to be introduced, preceded by ] (''N''-allylnorcodeine) in 1915 and followed by ] in 1960 and ] in 1963.<ref name="Aggrawal" /> Due to potent activation of the ], nalorphine produces ]s such as ], ], ], and ]s, and for this reason, is no longer used medically.<ref name="Glatt2012" /><ref name="Aggrawal" /><ref name="SatoskarRege2015">{{cite book| vauthors = Satoskar RS, Rege N, Bhandarkar SD |title=Pharmacology and Pharmacotherapeutics|url=https://books.google.com/books?id=h2drCgAAQBAJ&pg=PA166|date=27 July 2015|publisher=Elsevier Health Sciences APAC|isbn=978-81-312-4371-8|pages=166–}}</ref>

==Pharmacology==


===Pharmacodynamics===
{{pharmacology-stub}}
Nalorphine acts at two ]s — the ] (MOR) where it has ]ic effects, and at the ] (KOR) (K<sub>i</sub> = 1.6 nM; ] = 483 nM; ] = 95%) where it exerts high-] ]/near-] characteristics.<ref name="GharagozlouHashemi2006">{{cite journal | vauthors = Gharagozlou P, Hashemi E, DeLorey TM, Clark JD, Lameh J | title = Pharmacological profiles of opioid ligands at kappa opioid receptors | journal = BMC Pharmacology | volume = 6 | issue = 1 | pages = 3 | date = January 2006 | pmid = 16433932 | pmc = 1403760 | doi = 10.1186/1471-2210-6-3 | doi-access = free }}</ref>

==Chemistry==

===Analogues===
Nalorphine has a number of ]s including ] (the ] analogue), ] (] analogue), ] (dihydromorphine), and a number of others as well as a number of ]-based analogues.<ref>{{cite book|url=https://books.google.com/books?id=vwAHCAAAQBAJ&q=dihydronalorphine&pg=PA507|title=Opioid Analgesics: Chemistry and Receptors | vauthors = Casy AF, Parfitt RT |date=29 June 2013|publisher=Springer Science & Business Media|via=Google Books|isbn=9781489905857}}</ref>

===Synthesis===
]).</ref>]]{{clear-left}}

More recently, it has become much more commonplace to use ] instead of ] for the ] demethylation step. See for example the ] or the synthesis of ] for further examples of this.
