What is Austedo?

Austedo (deutetrabenazine) is used to treat chorea (sudden involuntary movements) caused by Huntington's disease (an inherited disease that causes the progressive breakdown of nerve cells in the brain). It is not a cure for Huntington's disease and will not treat other symptoms of this condition.

Austedo is also used in adults to treat symptoms of tardive dyskinesia (TD), a nervous system disorder. Tardive dyskinesia causes repetitive uncontrolled muscle movements, usually in the face (chewing, lip smacking, frowning, tongue movement, blinking or eye movement).

Austedo's drug class VMAT2 inhibitors (vesicular monoamine transporter 2 inhibitors. It works by changing the activity of certain natural substances in the brain that affect nerves and muscles. 

Austedo tablets are taken twice daily with food, and Austedo XR (extended-release tablet) is taken once daily.

How does Austedo work?

Body movement or motor function is controlled in the brain by nerve cells (neurons) that speak to each other by passing chemical messengers (neurotransmitters) from one nerve cell to another nerve cell.

In movement disorders such as Huntington’s disease and tardive dyskinesia there can be a problem with this system and by lowering the amount of chemical messengers between the nerve cells you relieve the uncontrolled movements.

A protein called VMAT2 controls how much chemical messenger is stored in the nerve cell and how much is released. The VMAT2 inhibitors block VMAT2 which means there is a lower amount of neurotransmitter available and therefore reduces the unwanted body movements.
