Dezocine (Dalgan, WY-16225) is an opioid analgesic related to pentazocine, with a similar profile of effects that include analgesic action and euphoria at low doses,[1] but produces dysphoria and hallucinations at high doses, most likely due to action at κ-opioid receptors.[2][3]
Dezocine has been found to be an effective painkiller comparable to meperidine (pethidine),[4] and so is a more effective analgesic than pentazocine, but causes relatively more respiratory depression than pentazocine.[5] It is a useful drug for the treatment of pain,[6] but side effects such as dizziness limit its clinical application,[7] and it can produce opioid withdrawal syndrome in patients already dependent on other opioids.[8]
Dezocine is unusual among opioids as it is the only primary amine known to be an active opioid. It is a mixed agonist-antagonist as with other drugs in this class,[9] and despite having a stronger respiratory depressant effect than morphine, dezocine shows a ceiling effect on its respiratory depressive action so above a certain dose this effect does not get any more severe.[10]
