AI summarySynthesized from FDA + DailyMed + ClinicalTrials.gov data
XENAZINE (tetrabenazine) is an oral tablet approved in 2008 that functions as a Vesicular Monoamine Transporter 2 (VMAT2) inhibitor. It is indicated for the treatment of chorea associated with Huntington's disease by depleting monoamine neurotransmitters in the central nervous system. The drug works by inhibiting VMAT2, which reduces the availability of dopamine and other monoamines at the synaptic cleft. XENAZINE represents the only FDA-approved treatment specifically targeting the hyperkinetic movements characteristic of Huntington's disease.
