Baclofen prolongs the analgesic effect of fentanyl in man

Br J Anaesth. 1985 Oct;57(10):954-5. doi: 10.1093/bja/57.10.954.

Abstract

Pretreatment with baclofen prolonged the duration of fentanyl-induced analgesia from 18 to 30 min in patients undergoing neurosurgical anaesthesia (fentanyl plus nitrous oxide in oxygen). This observation is consistent with a potentiating effect of GABA on opioid analgesia.
