(-)-Phenazocine is an opioid analgesic drug, which is related to pentazocine and has a similar profile of effects. (-)-Phenazocine is a potent mu opioid receptor agonist. In addition, (−)-phenazocine is also known to bind to δ opioid receptors (DOR) and κ opioid receptors (KOR). Regarding their analgesic potency, (−)-phenazocine was twenty times more potent than morphine in the hot plate test and sixty times more potent than its dextro enantiomer when it was subcutaneously (s.c.) administered
