Trigeminal neuralgia (TN) is a debilitating condition characterized by sudden, severe facial pain. IV medications for acute TN exacerbations have not been investigated in randomized controlled trials (RCTs). Oral medications are often insufficient for acute attacks, and surgery is not immediately available. We conducted an RCT to evaluate IV fosphenytoin therapy (IFT) as a rapid-acting rescue treatment for acute TN exacerbations. We hypothesized that, compared with placebo, IFT would reduce acute TN pain.
Noro et al. (Thu,) studied this question.
