Carbamazepine is prescribed for which type of seizures?

• A. Absence
• B. Partial
• C. Generalized
• D. Myoclonic

Answer: (B)

Carbamazepine works mainly by blocking voltage-gated sodium channels, which stabilizes neuronal membranes and reduces the rapid, repetitive firing of neurons. This makes it particularly effective for focal (partial) seizures, which originate in a specific brain region—the drug helps prevent those localized discharges from spreading. Absence seizures involve different thalamocortical networks and are better treated with other drugs like ethosuximide or valproate; carbamazepine can even worsen absences in some cases. Myoclonic seizures also often respond poorly to carbamazepine. So, the best match is partial seizures.
