Neuropathic Pain – Current Treatment – Treatment Algorithms: Claims Data Analysis – Trigeminal Neuralgia (US)

Trigeminal neuralgia (TN) is a rare and painful disorder, usually triggered by innocuous stimuli, resulting in paroxysmal neuropathic facial pain in the regions served by the trigeminal nerve. Carbamazepine (Tegretol, generics) is the only therapy formally approved for TN in the United States, but its use is limited by safety and tolerability concerns. Therefore, TN patients may be managed by a variety of off-label medications along their treatment journey, including oxcarbazepine (Supernus Pharmaceuticals’ Oxtellar XR, generics), gabapentin (Neurontin, generics), opioid analgesics, and even neuromuscular blocking agents (Allergan’s Botox). However, a substantial portion of TN patients are treatment-refractory, and better treatment options for these patients are needed.
