Systemic administration of morphine in horses is controversial and requires more investigation. In literature, there is no study about intravenous use of morphine in Arabian Horses; because of that, 12 animals were selected and distributed into two groups, GC (5mL NaCl 09%, iv) and GM (0,1mg/Kg morphine, iv). Basal evaluation was performed in T-20 and T-10, drugs were injected in T0 and other measures were carried out in T30min, T60min, T90min, T2h, T3h, T6h, T12h and T24h. Parameters evaluated included heart and respiratory rate, body temperature, height of the head in relation to the ground, eye and lip drop, intestinal motility and ataxia. Besides, latency to urinate and defecate, and the percentage of animals which urinated or defecated were observed. There were no differences in the parameters, except in intestinal motility that was reduced from T30 to T2h in GM. So, we concluded that intravenous application of morphine (0.1mg/Kg) was safe and did not promot clinical or behavioral changes in Arabian Horses.
