What does it do?

Phenytoin is an active ingredient in anticonvulsants that works primarily to prevent and control seizures. This ingredient suppresses excessive excitability in nerve cells, helping to reduce seizures.

Phenytoin regulates the flow of sodium ions in the nerve cells of the brain to prevent excessive transmission of nerve signals. This helps to prevent the excessive excitation of nerve cells, thereby preventing seizures.
