Primidone-d₅ is the deuterium labeled Primidone. Primidone is a potent anticonvulsant agent of the barbiturate class. Primidone is a neuronal voltage-gated sodium channel (VGSC) blocker and can be used for the study of epilepsy, essential tremor, and Psychiatric disorders.

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.
