HOW DO CENTRAL MONOAMINE-DEPLETING AGENTS WORK?

Central monoamine-depleting agents are drugs used for treating uncontrolled, involuntary movement disorders related to Huntington's disease or tardive dyskinesias.

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

Central monoamine-depleting agents inhibit vesicular monoamine transporter 2 (VMAT2), causing dopamine depletion in the central nervous system. VMAT2 is a protein that controls the amount of dopamine stored in the nerve cell and the amount released. Inhibiting VMAT2 leads to a lower amount of dopamine available, thereby reducing unwanted body movements.
