Description
Dilantin, containing the active ingredient phenytoin, is an anticonvulsant medication used to control seizures. Specifically utilized for the prevention and management of tonic-clonic (grand mal) seizures and complex partial seizures, Dilantin works by slowing down impulses in the brain that cause seizures. Phenytoin, classified as a hydantoin derivative, stabilizes the threshold against hyperexcitability caused by excessive stimulation or environmental changes capable of reducing the membrane sodium gradient.
