What is a medical treatment option for trigeminal neuralgia?

• A. Dilantin or Tegretol
• B. Ibuprofen
• C. Lisinopril
• D. Metformin

Answer: (A)

Trigeminal neuralgia is best treated by medications that calm hyperactive nerves. Anticonvulsants do this by stabilizing nerve membranes and reducing the abnormal firing that causes the sudden, sharp facial pain characteristic of this condition.

Carbamazepine (Tegretol) is the classic first-line choice because it reliably decreases trigeminal nerve excitability and lowers the frequency and intensity of pain episodes. Phenytoin (Dilantin) is another anticonvulsant with the same general effect on neural firing, so it reflects the same treatment strategy of dampening nerve activity. That shared mechanism is why this option is the right fit for managing trigeminal neuralgia.

The other drugs listed don’t address the neuropathic pain mechanism of trigeminal neuralgia. Ibuprofen targets inflammatory pain, while lisinopril and metformin address blood pressure/heart failure and diabetes management, respectively, and don’t relieve the characteristic nerve hyperexcitability.
