Tetrabenazine is the only US Food and Drug Administration-approved drug for Huntington's disease, indicated for treatment of chorea associated with Huntington's disease[1,3,4]. It reversibly inhibits central vesicular monoamine transporter (VMAT) transporter type 2 which acts on the various monoaminergic systems in the brain, e.g., dopamine, serotonin and noradrenaline[5] Tetrabenazine binds predominately to VMAT2 and has been shown to reversibly inhibit monoamine uptake in pre-synaptic vesicles, resulting in monoamine depletion of serotonin, dopamine, and nor-epinephrine [6] thereby reducing chorea[7].
In Neuro-2a neuroblastoma cell line, Tetrabenazine loaded nanoemulsion showed 100.00±1.23%, 100.00±2.01% and 100.00±2.09% cell viability when treated at the dose of 4.8ng/mL, 2.4ng/mL and 9.6ng/Ml[2]. When used bovine chromaffin cells (BCCs) challenged with repeated pulses of high K+ Upon repeated K+ pulsing, the exocytotic catecholamine release responses were gradually decaying. However, when cells were exposed to tetrabenazine, responses were mildly augmented and decay rate delayed[8].
In rat, The superiority of tetrabenazine nanoemulsion for delivering of tetrabenazine via intranasal route bypassing BBB[2]. In mice, Cold-water immersion-induced acute stress diminished the locomotor activity, exploratory behaviour, motor activity and social behaviour along with increase in the plasma corticosterone levels. Administration of tetrabenazine (1 and 2 mg/kg, i.p.), abolished the acute stress-induced behavioural and biochemical changes in a dose-dependent manner[9].
