Tetrabenazine is a highly selective and reversible centrally-acting dopamine depleting drug that works by inhibiting a molecule known as vesicular monoamine transporter 2 (VMAT2). Xenazine was approved by the FDA on August 15, 2008, for the treatment of chorea associated with Huntington's disease, based on the results of a double-blind, placebo-controlled, Phase 3 study that found Xenazine significantly reduced patients' chorea burden, improved global outcome scores, and was generally safe and well tolerated. Additional post-marketing preclinical studies further elucidating the safety profile of the product are being conducted. Tetrabenazine has been available in Europe for more than 30 years and in Canada since 1996.
Neurons talk to each other using chemical signals called neurotransmitters. Scientists at St. Jude Children's Research Hospital have drawn on structural biology expertise to determine structures of vesicular monoamine transporter 2 (VMAT2), a key component of neuronal communication.
