TY - JOUR AU - Wang Chun-an AU - Yang Yan-hua AU - Chen Yi-zhang PY - 2016 TI - Effect of fentanyl on midbrain units and its antagonism by naloxone in rabbits JF - Acta Pharmacologica Sinica; Vol 3, No 3 (September 1982): Acta Pharmacologica Sinica Y2 - 2016 KW - N2 - In the 92 units, 24 units (26%) showed excitatory effects; 33 (36%) inhibitory; 13 (14%) inhibitory-excitatory and 22 (24%) no effect. Naloxone showed a reversal effect on both fentanyl-excitation and fentanyl-inhibition, but the time course of naloxone—reversal for excitatory effect was much shorter than that for inhibitory effect.
