Eletriptan-d₅ hydrochloride 

Eletriptan-d₅ (hydrochloride) is the deuterium labeled Eletriptan hydrochloride[1]. Eletriptan (UK-116044) hydrochloride is a highly selective and orally active serotonin 5-HT1B and 5-HT1D receptor agonist, with pKi values of 8.0 and 8.9, respectively. Eletriptan hydrochloride has inhibitory effects on markers of neurogenic inflammation in rats. Eletriptan hydrochloride can be used for researching migraine[2].

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].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
