Olopatadine-d₃ hydrochloride 

Olopatadine-d₃ (hydrochloride) (ALO4943A-d3) is the deuterium labeled Olopatadine hydrochloride. Olopatadine hydrochloride (ALO4943A) is a histamine blocker used to treat allergic conjunctivitis[1][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].
