Randomized Controlled Trial Clinical Trial
Lamotrigine for central poststroke pain: a randomized controlled trial.
Central poststroke pain (CPSP) is usually difficult to treat. Amitriptyline, the only oral preparation shown to be effective in a randomized controlled trial, is often associated with a range of side effects related to the many mechanisms of actions of tricyclic antidepressants. We investigated the effect of lamotrigine, a drug that reduces neuronal hyperexcitability, on poststroke pain. ⋯ Oral lamotrigine 200 mg daily is a well tolerated and moderately effective treatment for central poststroke pain. Lamotrigine may be an alternative to tricyclic antidepressants in the treatment of CPSP.
