Comparison b/w Carbamazepine vs Oxcarbazepine in Treatment of Trigeminal Neuralgia

Carbamazepine is a conventional drug used to treat trigeminal neuralgia. It primarily works by blocking voltage-gated sodium channels in nerve cells, which prevents rapid and repetitive firing of action potentials and reduces abnormal electrical activity in the brain.

Oxcarbazepine is comparatively new approved drug in the treatment of TGN. Oxcarbazepine is a prodrug that is rapidly converted to its active metabolite, (monohydroxy metabolite or MHD). This active form works by blocking voltage-sensitive sodium channels in the brain, which stabilizes over-excited nerve membranes and prevents the rapid spread of abnormal electrical activity
