Austedo XR is a medication approved for the treatment of tardive dyskinesia [1]. Tardive dyskinesia is a movement disorder that can be a side effect of certain medications, particularly antipsychotics [1]. The active ingredients in Austedo XR are deutetrabenazine and valbenazine [1]. Deutetrabenazine works by affecting the amount of certain natural substances in the brain, while valbenazine specifically targets VMAT2, a protein involved in transporting neurotransmitters [1].

Austedo XR, containing deutetrabenazine, is designed to manage involuntary movements associated with tardive dyskinesia [1]. It functions by altering the levels of dopamine, a neurotransmitter implicated in the development of tardive dyskinesia [1]. Deutetrabenazine is a deuterium-modified form of tetrabenazine, which allows for slower metabolism and potentially a more stable effect [1].
