Scientific Name: Tetrabenazine
Brand Name: Nitoman, Xenazine
Company Owner: Not Available
Mechanism Of Action Tetrabenazine is a reversible human vesicular monoamine transporter type 2 inhibitor (Ki = 100 nM) . It acts within the basal ganglia and promotes depletion of monoamine neurotransmitters serotonin, norepinephrine, and dopamine from stores. It also decreases uptake into synaptic vesicles. Dopamine is required for fine motor movement, so the inhibition of its transmission is efficacious for hyperkinetic movement. Tetrabenazine exhibits weak in vitro binding affinity at the dopamine D2 receptor (Ki = 2100 nM) .
Description of the Drug: Tetrabenazine is a vesicular monoamine transporter 2 (VMAT) inhibitor used for the management of chorea associated with Huntington’s Disease.
