Are there alternative treatments for chorea?

Deutetrabenazine, a related drug, is approved for treating chorea associated with Huntington's disease and is marketed as Austedo [2]. Deutetrabenazine is chemically similar to tetrabenazine but involves deuterium, a heavier isotope of hydrogen [4]. This alteration can affect how the drug is metabolized in the body, potentially leading to different dosing schedules and tolerability profiles compared to tetrabenazine [4].
