Fexofenadine-d₁₀ hydrochloride  (Synonyms: MDL-16455-d₁₀ hydrochloride; Terfenadine carboxylate-d₁₀ hydrochloride)

Fexofenadine-d₁₀ (hydrochloride) is deuterium labeled Fexofenadine (hydrochloride). Fexofenadine hydrochloride (MDL-16455 hydrochloride), a H1R antagonist, is an anti-allergic agent used in seasonal allergic rhinitis and chronic idiopathic urticarial (person aged ≥16 years)[1].

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].
