Medetomidine

Description

Indications

Medetomidine Hydrochloride is indicated for use as a sedative and analgesic in dogs over 12 weeks of age to facilitate clinical examinations, clinical procedures, minor surgical procedures not requiring muscle relaxation, and minor dental procedures where intubation is not required. The IV route of administration is more efficacious for dental care.

Side effects

Bradycardia with occasional atrioventricular blocks will occur together with decreased respiratory rates. Body temperature is slightly or moderately decreased. Urination typically occurs during recovery at about 90 to 120 minutes posttreatment. In approximately 10% of treated dogs, occasional episodes of vomiting occur between 5 to 15 minutes posttreatment. An increase in blood glucose concentration is seen due to α2-adrenoreceptor-mediated inhibition of insulin secretion.

Precautions

In extremely nervous or excited dogs, levels of endogenous catecholamines are high due to the animal’s state of agitation. The pharmacological response elicited by α2-agonists (e.g., medetomidine) in such animals is often reduced, with depth and duration of sedative/analgesic effects ranging from slightly diminished to nonexistent. Highly agitated dogs should therefore be put at ease and allowed to rest quietly prior to receiving Medetomidine Hydrochloride. Allowing dogs to rest quietly for 10 to 15 minutes after injection may improve the response to Medetomidine Hydrochloride. In dogs not responding satisfactorily to treatment with Medetomidine Hydrochloride, repeat dosing is not recommended.
