Mechanism of Action:

VMAT2 inhibition can help regulate dopamine function.8

Voiceover:

Maintaining a balance in the level of dopamine is essential for controlled movement.


Dopamine signaling is facilitated by vesicular monoamine transporter 2, or VMAT2, which transports monoamines, including dopamine, from the cytosol into synaptic vesicles, keeping them ready for subsequent release in response to an action potential.


When an action potential reaches the nerve terminal of the presynaptic neuron, dopamine is released from the synaptic vesicles into the synaptic cleft.


This dopamine binds to receptors on the postsynaptic neuron, thereby signaling movement.


Excess dopamine signaling manifests as abnormal involuntary movements.


AUSTEDO® (deutetrabenazine) is a VMAT2 inhibitor.


Deutetrabenazine contains deuterium, a naturally occurring heavy version of hydrogen. Deuterium forms stronger molecular bonds with carbon atoms, thereby extending the half-life of therapeutic metabolites.


The precise mechanism by which deutetrabenazine exerts its effects on abnormal involuntary movements is unknown. It is believed to be related to its effect as a reversible depleter of monoamines, including dopamine, from nerve terminals.


Deutetrabenazine binds to VMAT2 on the vesicle in the presynaptic neuron and inhibits the uptake of dopamine into synaptic vesicles.


Dopamine molecules collect outside the blocked VMAT2 and are degraded by monoamine oxidase.


Reducing dopamine levels in the presynaptic neuron results in less dopamine signaling to the postsynaptic neuron.


Limiting dopamine signaling is believed to lead to fewer abnormal involuntary movements.
