Fosphenytoin 是一种磷酸酯前药，可替代静脉注射苯妥英，用于急性干预癫痫发作。Fosphenytoin 在肠胃外给药可水解成具有抗惊厥作用的苯妥英。Fosphenytoin 可用于多种给药方式，如静脉注射和腹腔注射。

Fosphenytoin Sodium-d10 是 Fosphenytoin Sodium 的氘代化合物。Fosphenytoin Sodium 的 CAS 号为 92134-98-0。Fosphenytoin sodium 是 phenytoin 的前体药物，具有抗惊厥等活性。它是电压门控钠通道阻滞剂。

Phenytoin-d10 is intended for use as an internal standard for the quantification of phenytoin by GC- or LC-MS. Phenytoin is an anticonvulsant agent and active metabolite of fosphenytoin. Phenytoin is formed from fosphenytoin by tissue phosphatases. It inhibits neuronal voltage-gated sodium channels in a voltage-dependent manner. Phenytoin reduces the neuronal firing frequency and decreases the amplitude of excitatory post-synaptic potentials (EPSPs) in electrically stimulated rat corticostriatal slices. It protects against seizures induced by maximal electroshock (MES) in mice. Formulations containing phenytoin have been used in the treatment of tonic-clonic seizures and status epilepticus.
