Metabolite Identification
Common NameDetomidine
DescriptionA profound lethargy and characteristic lowering of the head with reduced sensitivity to environmental stimuli (sound, pain, etc.) are seen with detomidine. A short period of reduced coordination is characteristically followed by immobility and a firm stance with front legs spread. Following administration there is an initial increase in blood pressure, followed by bradycardia and second degree atrioventricular block (this is not pathologic in horses). The horse commonly sweats to excess, especially on the flanks and neck. Other side effects reported include pilo erection (hair standing erect), ataxia, salivation, slight muscle tremors, and (rarely) penile prolapse. An agonist of receptors, adrenergic alpha-2 that is used in veterinary medicine for its analgesic and sedative properties. It is the racemate of dexmedetomidine. [PubChem]; As detomidine is an arrhythmogenic agent, extreme care should be exercised in horses with cardiac disease, and in the concurrent administration of other arrhythmogenics. The concurrent use of potentiated sulfonamide antibiotics is considered particularly dangerous. Detomidine is a poor premedication when using Ketamine as an anesthetic in horses. Detomidine is a sedative with analgesic properties. 2-adrenergic agonists produce dose-dependent sedative and analgesic effects, mediatated by activation of catecholamine receptors, thus inducing a negative feedback response, reducing production of excitatory neurotransmitters. Due to inhibition of the sympathetic nervous system, detomidine also has cardiac and respiratory effects and an antidiuretic action. Detomidine is an imidazole derivative and I-adrenergic agonist, used as a large animal sedative, primarily used in horses. It is usually available as the salt detomidine hydrochloride. It is a prescription medication available to veterinarians sold under the trade name Dormosedan.
