Austedo XR is a medication used to treat chorea associated with Huntington's disease and tardive dyskinesia [1]. It is an extended-release formulation of deutetrabenazine [1].
How does Austedo XR work?
Austedo XR works by reducing the amount of a chemical called dopamine in the brain [1]. Dopamine is a neurotransmitter that plays a role in controlling movement. In conditions like Huntington's disease and tardive dyskinesia, there can be an imbalance of dopamine, leading to involuntary movements [1].

Austedo XR is an extended-release version of Austedo, meaning it is designed to release the medication into the body more slowly over time [1]. This can allow for less frequent dosing compared to the immediate-release formulation [1].
