Head-to-Head: which drug stops facial pain better?

This study compares two drugs, carbamazepine and oxcarbazepine, to see which one provides better pain relief for people with trigeminal neuralgia, a condition that causes sudden, severe facial pain. About 122 adults aged 18 to 60 with the condition for at least two weeks will take one of the two drugs. The main goal is to measure pain relief using a simple 0-to-10 pain scale, and the study will also track side effects like liver problems, nausea, and dizziness.
