title: Morphine and its potentiated form: effects on pain sensitivity in rats.
abstract: We studied the effects of morphine and its potentiated form on nociceptive thresholds in rats with the morphine withdrawal syndrome. Repeated combination (bipathic) treatment with morphine and its potentiated form increased nociceptive threshold and, therefore, activated the nociceptive system in the brain.
