Pentazocine is a synthetic opioid analgesic of the benzomorphan class. It acts as a partial agonist at the κ-opioid receptor and a weak antagonist at the μ-opioid receptor. This dual action profile gives pentazocine a lower potential for abuse and respiratory depression compared to full μ-opioid agonists like morphine, but it can still cause psychotomimetic effects like hallucinations and dysphoria.
