Select the therapeutic category primarily aimed at preventing seizures.

• A. Analgesics
• B. Anticonvulsants (Class)
• C. Antidepressants
• D. Vasodilators

Answer: (B)

Preventing seizures is achieved with anticonvulsants. These medications dampen brain excitability and stabilize neural activity, lowering the chance of seizures occurring. They may work by enhancing inhibitory signals (like GABA) or by blocking excitatory nerve activity through targets such as voltage-gated sodium or calcium channels, depending on the drug. Analgesics are for pain relief, antidepressants treat mood disorders and aren’t used primarily to prevent seizures (and can alter seizure thresholds in some cases), and vasodilators change blood vessel tone for cardiovascular conditions. So the therapeutic category aimed at seizure prevention is anticonvulsants.
