Austedo XR is a brand-name prescription medication used to treat chorea, a movement disorder associated with Huntington's disease, and tardive dyskinesia [1]. It is an extended-release formulation of deutetrabenazine [2].
How does Austedo XR work?
Austedo XR contains deutetrabenazine, which is believed to reduce involuntary movements by affecting the levels of certain chemicals in the brain, specifically dopamine [1]. Dopamine is a neurotransmitter that plays a role in controlling motor function [3]. By reducing dopamine levels, Austedo XR helps to alleviate the uncontrolled, jerky movements characteristic of chorea and tardive dyskinesia [1].
What is the difference between Austedo and Austedo XR?
Austedo XR is an extended-release version of Austedo. This means that the active ingredient, deutetrabenazine, is released into the body over a longer period, allowing for less frequent dosing compared to the immediate-release formulation of Austedo [2].
How long does Austedo XR take to work?
The effectiveness of Austedo XR can vary among individuals. Patients may begin to notice a reduction in involuntary movements within two weeks of starting treatment, with further improvement often observed over the following four to eight weeks [1].

The choice of treatment depends on the individual patient's condition, medical history, and response to therapy.
