Pharmacotherapy of Trigeminal Neuralgia
Trigeminal neuralgia (TGN) is a disorder characterized by brief but severe electric shock-like pain, which is abrupt in onset and termination, and is limited to the distribution of one or more divisions of the trigeminal nerve . It is further sub-classified into classical (CTN) and symptomatic forms (STN), the latter is associated with a demonstrable lesion on imaging apart from a vascular loop . STN should be suspected when a patient presents with bilateral symptoms or concomitant trigeminal sensory loss. The distinction is important as the treatment for both differs.
