Abstract

Prostaglandin E analogs have been shown to be effective in the treatment of refractory trigeminal neuralgia in patients with multiple sclerosis. Prostaglandin E inhibits the functions of T lymphocytes which are involved in the pathophysiology of cluster headache. Therefore, a double-blind, placebo-controlled, crossover study on the efficacy of misoprostol in chronic refractory cluster headache was performed. Eight patients were treated with 600 micrograms misoprostol and with placebo for a 2-week period. No differences in attack frequency, intensity, global impression, and side effects could be detected, suggesting that prostaglandin E analogs are not effective in the treatment of chronic cluster headache.
