What classification does Dilantin fall under?

Anticonvulsant
Antidepressant
Laxative
Antihistamine

The correct answer is: Anticonvulsant

Dilantin, also known by its generic name phenytoin, is classified as an anticonvulsant. This medication is primarily used to control seizures in individuals with epilepsy and other seizure disorders. It functions by stabilizing electrical activity in the brain and preventing the rapid firing of neurons that can lead to seizures. Understanding its classification as an anticonvulsant is crucial for those involved in medication administration, as it highlights the specific therapeutic use of Dilantin compared to other drug classes that serve entirely different purposes. For example, antidepressants are used to treat mood disorders, laxatives help relieve constipation, and antihistamines are commonly used to alleviate allergic reactions. Knowing the classification enhances a QMA's ability to provide appropriate care and respond to patient needs.
