Tiletamine is a dissociative anesthetic and pharmacologically classified as an NMDA receptor antagonist. It is related chemically to ketamine. Tiletamine hydrochloride exists as odorless white crystals.
It is used in veterinary medicine in the combination product Telazol (tiletamine/zolazepam, 50 mg/ml of each in 5 ml vial) as an injectable anesthetic for use in cats and dogs. It is sometimes used in combination with xylazine (Rompun) to chemically immobilize large mammals such as polar bears and wood bison. Telazol is the only commercially available tiletamine product in the United States. It is contraindicated in patients of an ASA score of III or greater and in animals with CNS signs, hyperthyroidism, cardiac disease, pancreatic or renal disease, pregnancy, glaucoma, or penetrating eye injuries.
Recreational use of telazol has been documented. Animal studies have also shown that tiletamine produces rewarding and reinforcing effects. Tiletamine products are classified as Schedule III controlled substances in the United States.
