Effects of NOP and MOP antagonists on antiallodynic effects of intrathecal SCH221510 (10 µg) and morphine (10 µg) in neuropathic pain. Antagonists were administered intrathecally 10 minutes before SCH221510 or morphine. Changes in SCH221510-induced increase in the paw withdrawal thresholds (A) and the percentage of maximum possible antiallodynic effect (B) after J-113397, naltrexone, or vehicle pretreatment at 0.5 hours after intrathecal SCH221510. Right panels: changes in morphine-induced increase in the paw withdrawal thresholds (B) and the percentage of maximum possible antiallodynic effect (D) after naltrexone, J-113397, or vehicle pretreatment at 0.5 hours after intrathecal morphine. *Statistically significant difference from the vehicle control (P < 0.05).
