Would it be ethosuximide, phenobarbital, phenytoin, clonazepam or oxazepam? Good, you chose A. Alright, let's go through the answers. Ethosuximide is a first line agent in absence seizures. It is non sedating and relatively safe to use in kids. B, phenobarb is not a first or even a second line agent. It causes excessive sedation. It is used in neonatal seizures because we like to sedate neonates who are having seizures and it can be protective in them. And we do use it in kids or in status epilepticus but we won't use it in kids who are trying to do better in school. The next choice phenytoin is not a good choice at all. It is a drug that we used to use a lot in kids, but because of the effects of gingival hyperplasia and other side effects, we've essentially stopped using it in kids. It is also risky because kids sometimes missed their doses, and that can actually cause more seizures. Clonazepam causes excessive sedation so we don't want to give this to children. And oxazepam is rarely used in epilepsy. And the reason why is because it is also sedating. Oxazepam however is commonly used in detoxification programs. And it's good because it's a long acting agent, it's not as addictive, and it works very well for those types of seizures that are seen in alcohol withdrawal. Here's another great question.
