Which drug is used as an adjunct in the treatment of seizures?

Zonegran, which is the correct answer, is an anticonvulsant medication primarily used to treat seizures, particularly in patients with epilepsy. As an adjunct therapy, it can be combined with other anticonvulsants to enhance seizure control and is beneficial for patients whose seizures are not fully managed by monotherapy alone.

Zaroxolyn, on the other hand, is a diuretic used to manage conditions like hypertension and edema, making it irrelevant in the context of seizure treatment. Chantix is used in smoking cessation, focusing on helping individuals quit smoking rather than addressing seizure disorders. Intuniv, which is primarily used in the treatment of attention deficit hyperactivity disorder (ADHD), is not specifically indicated for seizure management. Therefore, Zonegran stands out as the medication designed to assist specifically in the management of seizures, making it the appropriate choice among the options provided.
