Epidural administration of ALPHA-2 agonists promotes antinociceptive effect and amitraz acts on ALPHA-2 receptors. Antinociceptivo effect caused by pre-emptive epidural injection of 0.17mg kg-1 xylazine (GX) or 0.1mg kg-1 amitraz diluted in lipidic emulsion (GA) were evaluated, in 12 horses submitted by incisional model of inflammatory pain and evaluated about nociceptive threshold by mechanical stimulus (NTMS), by von Frey filaments. Xylazine produced maintenance of NTMS for 4 hours, while amitraz diluted in lipidic solution maintained NTMS for 24 hours. (AU)
