Development of tolerance to the antiallodynic effects of repeated intrathecal administration of SR16435 (3 µg) or buprenorphine (3 µg) in mice with neuropathic pain. (A) Changes in SR16435 and buprenorphine-induced increase in paw withdrawal thresholds (g). (B) Changes in SR16435- and buprenorphine-induced percentage of maximum possible antiallodynic effects. Mice were tested each day at 0.5 hours after the drug administration. ▪ is SR16435; ● is buprenorphine. #Statistically significant difference from the antiallodynic effects of SR16435 on day 1 of the treatment. *Statistically difference from the antiallodynic effects of buprenorphine on day 1 (P < 0.05).
