GtoPdb Ligand ID: 8707

Synonyms: Austedo® | SD-809 | SD809 | tetrabenazine D6
deutetrabenazine is an approved drug (FDA (2017))
Compound class: Synthetic organic
Comment: This is an orally available, deuterated analogue of tetrabenazine which can be administered in lower doses and in a simplified dosing regimen. Deutetrabenazine is the first ever deuterated drug to be approved.

In drug discovery, replacing hydrogen atoms in drug compounds with deuterium (deuteration) is a technique employed to inhibit degradation of the drug and its active metabolites. The presence of the deuterium atoms attenuates CYP2D6-driven metabolic breakdown of the compound. This effects an increase in circulating half-lives and improves the duration of therapeutic effect and decreases the dose required to achieve therapeutic concentration [4].
