Fosphenytoin-d10 (disodium) is deuterium labeled Fosphenytoin (disodium). Fosphenytoin sodium is a phenytoin prodrug with similar anticonvulsant properties. Its main mechanism is to block frequency-dependent, use-dependent and voltage-dependent neuronal sodium channels, and therefore limit repetitive firing of action potentials.

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].
