HOW DO VMAT2 INHIBITORS WORK?

Vesicular monoamine transporter 2 (VMAT2) inhibitors are drugs used for treating uncontrolled, involuntary movements associated with Huntington’s disease, tardive dyskinesia, or Tourette’s syndrome.

The exact mechanism of involuntary movement disorder is not known. However, excess dopamine or increased sensitivity to dopamine receptors has been known to play a dominant role in uncontrolled, involuntary movements.

VMAT2 inhibitors block VMAT2 causing dopamine depletion in the central nervous system. VMAT2 is a protein that controls the amount of dopamine stored in the nerve cells and the amount released. Inhibiting VMAT2 leads to a lower amount of available dopamine, thereby reducing unwanted body movements.
