Metazocine is an opioid analgesic related to pentazocine. While metazocine has significant analgesic effects,[1] mediated through a mixed agonist-antagonist action[2] at the mu opioid receptor,[3] its clincial use is limited by dysphoric and hallucinogenic effects which are most likely caused by activity at kappa opioid receptors[4] and sigma receptors.[5][6]
