Accelerometric comparison of the locomotor pattern of horses sedated with xylazine hydrochloride, detomidine hydrochloride, or romifidine hydrochloride

Abstract: Accelerometric evaluation of horses administered α2-adrenoceptor agonist drugs revealed more prolonged sedative effects of romifidine, compared with effects of xylazine or detomidine. Accelerometry could be useful in assessing the effects of other sedatives and analgesics. Accelerometric data may be helpful in drug selection for situations in which a horse's balance and coordination are important.

“…There is currently no alternative (reversible) equine model in which to study ataxia. A side effect of α‐2 agonists is induction of ataxia ; 2 significant advantages of a xylazine‐induced equine ataxia model are that the resulting ataxia is dose‐dependent, as seen here and as has been reported previously , and the mechanism of development of the gait deficits is the same across animals. Here, all HD horses were graded 3 and LD horses were grade 1 or 2 for ataxia.…”

“…Gait patterns measured using 3‐dimensional accelerometry were altered by either intravenous xylazine, detomidine or romifidine (López‐Sanromán et al . ) or sublingual detomidine (López‐Sanromán et al . ).…”

“…Effects of romifidine (40 µg/kg IV) on stride frequency were noted for 90 min compared with only 30 min for xylazine and detomidine. Speed was reduced for up to 105 min with romifidine, compared with 30–45 min for xylazine and detomidine, respectively . Romifidine may be a good choice in situations where a horse's balance and coordination are important, but a sustained sedative effect is still desired, such as traveling in a trailer.…”
