Opioid system mediated anti-nociceptive effect of agomelatine in mice.

Aims: This study was planned to examine the antinociceptive efficacy of agomelatine against acute mechanical, thermal, and chemical nociceptive stimuli, as well as to determine the opioid receptor subtypes mediating these effects.

Main Methods: Tail-clip, hot-plate, and acetic acid-induced writhing tests were performed to evaluate anti-nociceptive effect. Besides, possible effect of agomelatine on the motor coordination of animals was assessed with a Rota-rod test.
