Tetrabenazine

Tetrabenazine is a VMAT-inhibitor used for treatment of hyperkinetic movement disorder. (In Vivo) :Tetrabenazine (subcutaneous injection, 1-10 mg/kg, once) can reduce the aggressive behavior in a dose-dependent manner and the levels of neurotransmitter molecules NE, DA and 5-HT in adult male mice.Tetrabenazine (intraperitoneal injection, 0-2 mg/kg, once) has selective effects on movement which can significantly attenuate morphine-induced hypermobility but oral tremors and stereotyped behaviors in male ICR mice.Tetrabenazine (intraperitoneal injection, 0.25-2 mg/kg, once a week) increases tremulous jaw movement (TJM) in a dose-dependent manner in adult male Sprague-Dawley rat.
