Etifoxine-d₅ 

Etifoxine-d₅ is the deuterium labeled Etifoxine. Etifoxine, a non-benzodiazepine GABAergic compound, is a positive allosteric modulator of α1β2γ2 and α1β3γ2 subunit-containing GABAA receptors. Etifoxine reveals anxiolytic and anticonvulsant properties in rodents[1][2][3].

Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into drug molecules, largely as tracers for quantitation during the drug development process. Deuteration has gained attention because of its potential to affect the pharmacokinetic and metabolic profiles of drugs^[1].
