Consider these three drugs: divalproex (Depakote), carbamazepine (Tegretol), gabapentin (Neurontin). Which drug also belongs with this group?
- A. Clonazepam (Klonopin)
- B. Lamotrigine (Lamictal)
- C. Risperidone (Risperdal)
- D. Aripiprazole (Abilify)
Correct Answer: B
Rationale: The correct answer is B: Lamotrigine (Lamictal). All the drugs listed are commonly used in the treatment of epilepsy and mood disorders. Lamotrigine is often prescribed alongside divalproex, carbamazepine, and gabapentin as a mood stabilizer and antiepileptic medication. It works by stabilizing electrical activity in the brain and preventing seizures. Clonazepam (A) is a benzodiazepine used for anxiety and seizures, not in the same class as the other drugs. Risperidone (C) and Aripiprazole (D) are antipsychotics used for schizophrenia and bipolar disorder, not primarily for epilepsy.
