[0192] Anti-NGF monoclonal antibody combined with opioid analgesics for postoperative pain

[0193] We evaluated the efficacy of an anti-NGF antibody in combination with an opioid analgesic (morphine) using a pain model that mimics postoperative pain. Each experiment included 16 animals (n=8 / group).

[0194] animal. For each experiment, 16 male adult Sprague Dawley rats (Harlan; Indianapolis, IN) weighing 200-220 g were housed under normal light conditions for at least one week prior to use with food and water ad libitum.

[0195] On the day before the operation, after acclimatizing the rats in the experimental cage for 2 hours, the rats were divided into two groups: one group received the antibody 15 hours before the operation, and the other group received the vehicle (5% glucose / 0.45 % saline USP). Anti-NGF antagonist antibody Mab 911 (see Hongo, et al., Hybridoma 19:215-227 (2000)) was administered intraperitoneally (i.p.) at a concentration of 0.3-20 mg / kg. Twenty-four...
