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.

Fosphenytoin is an effective neuroprotectant against ischemia-induced damage. In fosphenytoin (30 mg/kg, i.m.)-treated rat 5 min after ischemia episode, hippocampal CA1 pyramidal neurons remain at near control level (13.90 +/- 0.92), however, GFAP staining iss not significantly changed^[1]. In fosphenytoin (84 mg/kg)-treated rat, the relative bioavailability of fosphenytoin is 83%. In fully kindled female Wistar rats, fosphenytoin dose-dependently increases the focal seizure (afterdischarge) threshold. Seizure severity and duration at threshold are reduced only after the highest does of fosphenytoin tested (84 mg/kg)^[2].
