'''Piritramide''' ('''Dipidolor<sup>®</sup>''') is a synthetic [[opioid]] [[analgesic]] with about 65-75 percent of the mg-for-mg strength of morphine.  A common starting dose is 15 mg IV, equivalent to 10 mg of morphine hydrochloride. Piritramide is commonly used for the treatment of postoperative pain. Piritramide was discovered at [[Janssen Pharmaceutica]] in [[1960]] and is currently manufactured and distributed within continental Europe and some other places by Janssen-Cilag.
__NOTOC__
 
{{SI}}
Piritramide is available in tablets and ampoules of sterile solution for injection by all routes, and is used in Patient Controlled Analgesia units. In addition to PCA, piritramide is most often used in post-operative situations and emergency departments; some of its properties would seem to lend it well to chronic pain control as well. It is one of the longer-lasting opioids and has a plasma half-life of 3 to 12 hours. Piritramide tends to cause less respiratory depression and can take a while to have full effect especially if taken by mouth.

== Overview ==
Piritramide is also known as pirinitramide.  Its closest chemical relatives amongst well-known drugs are [[diphenoxylate]] (Lomotil<sup>®</sup>) and [[bezitramide]] (Burgodin<sup>®</sup>).
'''Piritramide''' ('''R-3365''', trade names '''Dipidolor''', '''Piridolan''', '''Pirium''' and others) is a synthetic [[opioid]] [[analgesic]] (narcotic painkiller) that is marketed in certain [[Europe]]an countries including: [[Austria]], [[Belgium]], [[Czech Republic]], [[Germany]] and the [[Netherlands]].<ref name = MD>{{cite web|title=Piritramide|work=Martindale: The Complete Drug Reference|publisher=Pharmaceutical Press|accessdate=22 April 2014|date=23 September 2011|editor=Brayfield, A|url=http://www.medicinescomplete.com/mc/martindale/current/6259-x.htm}}</ref> It comes in free form, is about 0.75x times as potent as [[morphine]] and is given [[parenterally]] (by injection) for the treatment of severe pain.<ref name = MD/><ref>{{cite journal|last=Kay|first=B|title=A clinical investigation of piritramide in the treatment of postoperative pain.|journal=British Journal of Anaesthesia|date=December 1971|volume=43|issue=12|pages=1167–71|doi=10.1093/bja/43.12.1167|pmid=4945251}}</ref> Nausea, vomiting, respiratory depression and constipation are believed to be less frequent with piritramide than with [[morphine]] (which is the gold standard opioid against which other opioids are compared and contrasted against) and it produces more rapid-onset analgesia (pain relief) when compared to morphine and [[pethidine]], after intravenous administration the onset of analgesia is as little as 1–2 minutes, which may be related to its great [[lipophilicity]].<ref name = SPC>{{cite web|title=FACHINFORMATION (Zusammenfassung der Merkmale des Arzneimittels)|trans_title=PROFESSIONAL INFORMATION (Summary of Product Characteristics)|work=Janssen|publisher=Janssen - Cilag Pharma GmbH|format=PDF|url=http://www.janssen-medinfo.at/sites/janssen_medinfo_at/themes/medinfo_at/images/Dipidolor_FI_20131206.pdf|accessdate=9 April 2014|date=November 2013}}</ref> The analgesic and sedative effects of piritramide are believed to be potentiated with phenothiazines and its emetic (nausea/vomiting-inducing) effects are suppressed.<ref name = SPC/> The [[volume of distribution]] is 0.7-1 L/kg after a single dose, 4.7-6 L/kg after steady-state concentrations are achieved and up to 11.1 L/kg after prolonged dosing.<ref name = SPC/>


Piritramide's most common trade name is '''Dipidolor'''<sup>®</sup> and it is used most heavily in the Netherlands, Denmark, and Germany.
==History & Regulation==
Piritramide was developed and patented in the Netherlands, at Janssen, in 1960.  It is part of an eponymous two-member class of opioids in clinical use with the other being [[bezitramide]] (Burgodin).  The closest chemical and structural relatives of piritramide in clinical use include the [[diphenoxylate]] family, [[fentanyl]] (both Janssen discoveries) and somewhat more distantly [[alphaprodine]].


Piritramide is a strong opioid and therefore is regulated much the same as morphine in all known jurisdictions. It was never introduced in the United States and is therefore a Schedule I/Narcotic controlled substance.  It is listed under international treaties and other laws such as the German Betäubungsmittelgesetz, the Austrian Suchgiftmittelgesetz, the Opium Laws of various other European countries, Canadian controlled substances act, UK Misuse of Drugs Act of 1971, and equivalents elsewhere. Strangely enough, bezitramide, which is not currently marketed in the United States is a Schedule II/Narcotic controlled substance.
Not being in clinical use in the United States, it is a Schedule I Narcotic controlled substance with a DEA ACSCN of 9642 and manufacturing quota of zero.<ref>http://www.deadiversion.usdoj.gov/fed_regs/quotas/2013/fr0620.htm</ref> It presumably has abuse potential, and appears on the European black market on occasion and has a handful of street names including "Pierrette" and "P".<ref>Inside Narcotics, 5th Edition, pp 347 (sidebar) "Piritramide -- what they say - Wien 8/iii/2002"</ref> LEXIS-NEXIS and other database searches do not show mentions of law enforcement contact with this drug in the United States.  Piritramide is specifically exempted from the Canadian controlled-substances law, and its relative bezitramide is a Schedule II controlled substance in the US, although not used there as of 2014.

Overview

Piritramide (R-3365, trade names Dipidolor, Piridolan, Pirium and others) is a synthetic opioid analgesic (narcotic painkiller) that is marketed in certain European countries including: Austria, Belgium, Czech Republic, Germany and the Netherlands.[2] It comes in free form, is about 0.75x times as potent as morphine and is given parenterally (by injection) for the treatment of severe pain.[2][3] Nausea, vomiting, respiratory depression and constipation are believed to be less frequent with piritramide than with morphine (which is the gold standard opioid against which other opioids are compared and contrasted against) and it produces more rapid-onset analgesia (pain relief) when compared to morphine and pethidine, after intravenous administration the onset of analgesia is as little as 1–2 minutes, which may be related to its great lipophilicity.[4] The analgesic and sedative effects of piritramide are believed to be potentiated with phenothiazines and its emetic (nausea/vomiting-inducing) effects are suppressed.[4] The volume of distribution is 0.7-1 L/kg after a single dose, 4.7-6 L/kg after steady-state concentrations are achieved and up to 11.1 L/kg after prolonged dosing.[4]

History & Regulation

Piritramide was developed and patented in the Netherlands, at Janssen, in 1960. It is part of an eponymous two-member class of opioids in clinical use with the other being bezitramide (Burgodin). The closest chemical and structural relatives of piritramide in clinical use include the diphenoxylate family, fentanyl (both Janssen discoveries) and somewhat more distantly alphaprodine.

Not being in clinical use in the United States, it is a Schedule I Narcotic controlled substance with a DEA ACSCN of 9642 and manufacturing quota of zero.[5] It presumably has abuse potential, and appears on the European black market on occasion and has a handful of street names including "Pierrette" and "P".[6] LEXIS-NEXIS and other database searches do not show mentions of law enforcement contact with this drug in the United States. Piritramide is specifically exempted from the Canadian controlled-substances law, and its relative bezitramide is a Schedule II controlled substance in the US, although not used there as of 2014.
