Answer for screen readers
The most likely effective drug for treating absence seizures among the options is Ethosuximide. It is often the first-line treatment for this type of seizure.
More Information
Ethosuximide is particularly effective for absence seizures because it targets the specific brain mechanisms involved in these seizures. While other drugs like valproic acid and lamotrigine can also be used, ethosuximide is often preferred due to its targeted action and comparatively fewer side effects.
Tips
A common mistake is to confuse absence seizures with other types of seizures. Drugs like phenytoin, which are effective for tonic-clonic seizures, are not typically the first choice for absence seizures.
