For seizure prevention in epilepsy and related CNS conditions, which drug class is prescribed?

• A. Antipsychotics
• B. Analgesics
• C. Anticonvulsants (Class)
• D. Antidiarrheals

Answer: (C)

Seizure prevention relies on anticonvulsants. These drugs modify neuronal excitability to prevent the initiation and spread of seizures, using different mechanisms such as blocking voltage-gated sodium channels, enhancing GABAergic inhibition, or affecting calcium channels. By dampening abnormal brain activity, they reduce seizure frequency and severity, which is why they’re the standard long-term therapy for epilepsy and related CNS conditions. Antipsychotics, analgesics, and antidiarrheals treat other symptoms and do not address the abnormal brain excitability that drives seizures. Common anticonvulsants include phenytoin, carbamazepine, valproate, lamotrigine, and gabapentin.
