Where is Deutetrabenazine used?

Deutetrabenazine is used for the treatment of:

Deutetrabenazine is a vesicular monoamine transporter-2 (VMAT2) inhibitor. This medicine is available for oral administration. The Food and Drug Administration (FDA) approved this medication.

How does Deutetrabenazine work?

Deutetrabenazine inhibits the vesicles that transmit dopamine to the part between two nerve cells where it is unconstrained. This kind of vesicle is known as a vesicular monoamine transporter 2 (VMAT2).

This drug reduces the total of dopamine released from nerve cells and dialing back the stimulation of adjacent nerve cells. This prevents the overstimulation of muscles that reasons to chorea.
