Correct Answer: B
Oxcarbazepine (Trileptal) is classified as an antiepileptic drug (AED) or anticonvulsant, used to treat partial seizures in adults and children. It works by stabilizing neuronal membranes and inhibiting repetitive firing of action potentials.
From Pharmacy Technician Certification Exam Review:
"Oxcarbazepine is used to treat seizure disorders and is part of the antiepileptic class, working similarly to carbamazepine." Other options are incorrect drug classes:
* Bronchodilator - used in asthma (e.g., albuterol)
* Vasodilator - used in angina or hypertension
* Decongestant - treats nasal congestion (e.g., pseudoephedrine)
