• 使用

  (?)-Pentazocine is a benzomorphan-type opiate with analgesic properties. It binds to opioid receptors (Ki values = 7.2, 31, and 5.7 nM for κ-, δ-, μ-opioid receptors, respectively) and to the type 1 σ-receptor (Kd = 12 nM). (?)-Pentazocine is abused with methylphenidate and other drugs. It is regulated as a Schedule IV compound in the United States. This product is intended for forensic and research applications.

• 世界保健機関（WHO）

  Pentazocine, which has both agonist and weak opioid antagonist activity, was introduced in 1967 for the treatment of moderate and severe pain. The risk of drug dependence is lower with pentazocine than with morphine-like drugs and pentazocine has been controlled under Section III of the 1971 Convention on Psychotropic Substances since 1984. The risk of dependence is now widely acknowledged to exist in vulnerable individuals and at least one country has applied controls analogous to those of Schedule I of the 1961 Single Convention on Narcotic Drugs. (Reference: (UNCPS3) United Nations Convention on Psychotropic Substances (III), , , 1971)

• 一般的な説明

  The benzomorphans are prepared synthetically and thus resultin several stereoisomers. The active benzomorphans arethose that have the equivalent bridgehead carbons in thesame absolute configuration of morphine (carbons 9, 13,and 14 of morphine). The only benzomorphan in clinical useis pentazocine, which is prepared as the 2(R), 6(R), 11(R)enantiomer (Chemical Abstracts numbering). Pentazocineis a mixed agonist/antagonist displaying differing intrinsicactivity at the opioid receptor subtypes. At the κ-receptor,pentazocine is a partial agonist and a weak antagonist.
  According to the manufacturer, a 50-mg dose of pentazocinehas about the same analgesic potency as 60 mg of codeineand about 1/50th the antagonistic activity of nalorphine.74Pentazocine is also an agonist at the κ-receptor, and thismay be responsible for the higher percentage of patients thatexperience dysphoria with pentazocine versus morphine.75Some evidence also exists that women respond better to κ-agonists than men. Pentazocine is available in a 50-mgtablet along with a low dose of the antagonist naloxone 0.5mg (Talwin NX). Naloxone 0.5 mg orally is expected tohave no pharmacological effect but is included to dissuadeIV drug abusers from dissolving and injecting Talwin NX.
