Phenytoin is primarily used to treat which condition?

Explanation:
Phenytoin is an anticonvulsant used to treat seizures. It works by stabilizing neuronal membranes and reducing excitability through inhibition of voltage-gated sodium channels, which helps prevent the rapid, repetitive firing that underlies seizures. This mechanism makes it effective for preventing various seizure types, especially generalized tonic-clonic seizures and some focal seizures. The other options describe drugs in different categories—antibiotics, antidepressants, and antipsychotics—which are not how phenytoin works or what it treats. So the best answer is that phenytoin is used to manage seizures.
