Biochem/physiol Actions

μ opioid receptor agonist that desensitizes both the μ opioid receptor and the δ opioid receptor on chronic exposure; narcotic analgesic, characterized by a gradual onset of action and prolonged, milder withdrawal; may also block L-type calcium channels independently of its effects on opioid receptors.
