Valbenazine decreases the availability of monoamine neurotransmitters by preventing their storage in synaptic vesicles 2. This is believed to be the reason behind its therapeutic effect in tardive dyskinesia although the exact mechanism is unknown.
- Mechanism of action
Valbenazine and its active meabolites bind to and inhibit vesicular monoamine transporter 2 (VMAT2)with high selectivity (valbenazine Ki = 150nM, [+]-α-HTBZ Ki = 1.98nM, NBI136110 Ki = 160nM) with no significant binding to VMAT1 (Ki <10microM for each) 2. This prevents the reuptake and storage of monoamine neurotransmitters noradrenaline, dopamine, and serotonin in synaptic vesicles making them vulnerable to metabolism by cytosolic enzymes. The presynaptic release of monoamine neurotransmitters is decreased due to the lack of vesicles with packaged neurotransmitter ready for release into the synapse. Neither valbenazine nor its active metabolite exhibit significant off target binding at dopamine, serotonin, or adrenaline receptors or uptake transporters at 10microM concentrations.
Target Actions Organism Avesicular monoamine transporter 2 (VMAT2) antagonistHumans - Absorption
Oral bioavailability of 49% Label. Tmax of 0.5-1h.
- Volume of distribution
92 Liters Label.
- Protein binding
Valbenazine is >99% bound to plasma proteins Label. Its active metabolite [+]-α-HTBZ is 64% bound to plasma proteins.
- Metabolism
Valbenzine is extensively metabolized to one active metabolite [+]-α-dihydrotetrabenazine ([+]-α-HTBZ) through hydrolysis of the valine ester reaching Cmax within 4-8 hours Label. It is also metabolized via oxidation by CYP3A4/5 to a mono-oxidzed metabolite NBI-136110 which also appears to pharmacologically active. [+]-α-HTBZ is metabolized by CYP2D6.

- Route of elimination
Roughly 60% is excreted in urine and 30% in feces Label. Less than 2% if the parent compound or active metabolite was excreted unchanged.
- Half-life
Both valbenazine and its active metabolite [+]-α-HTBZ have a half life of 15-22 hours Label.
- Clearance
7.2 Liters/hour Label.
