What is Dilantin primarily used for?

Controls heart rate and blood pressure
Inhibits seizures
Reduces inflammation
Aids digestion

The correct answer is: Inhibits seizures

Dilantin, known generically as phenytoin, is primarily used as an anticonvulsant medication to inhibit seizures. It is effective in managing various types of seizure disorders, particularly generalized tonic-clonic seizures and partial seizures. Dilantin works by stabilizing electrical activity in the brain and preventing the excessive neuronal firing that leads to seizures. The other options are not applicable for Dilantin's primary use. While some medications do control heart rate and blood pressure, reduce inflammation, or aid in digestion, those functions are not associated with Dilantin. Its specific role as a seizure preventive makes it a crucial medication in the treatment of epilepsy and conditions characterized by recurrent seizures.
