Dilantin Uses

Dilantin, with the generic name phenytoin sodium, is an oral medication indicated to treat grand-mal (tonic-clonic) and temporal lobe (psychomotor) seizures. It is also used to prevent & treat seizures that could occur during or after neurosurgery.

This is available in Dilantin 100 mg and 30 mg extended capsule dosage forms.

Dilantin Mechanism of Action

This anticonvulsant is thought to work by involving the voltage-dependent blockade of sodium channel membranes. This results in a reduction in sustained high-frequency neuronal discharges.
