Phenytoin, chemically known as 5,5-diphenylhydantoin, is an antiepileptic drug with a hydantoin structure. It exerts its therapeutic effects by stabilizing neuronal membranes through selective inhibition of voltage-gated sodium channels, thus reducing abnormal electrical activity in the brain and preventing seizures. Phenytoin is widely used in the treatment of epilepsy, addressing various seizure types. It is available in different formulations, including oral capsules and tablets. While primarily used for its anticonvulsant properties, phenytoin has been investigated for its potential in cardiac arrhythmias, neuropathic pain, and mood disorders, though its primary clinical application remains in epilepsy management.
