Transient minor improvement of high altitude headache by sumatriptan.

Abstract

High-altitude headache often fulfills the criteria of migraine. Therefore, we hypothesized that sumatriptan, a 5-HT1 receptor agonist specifically effective for treatment of migraine, would also alleviate high altitude headache. A randomized, placebo-controlled double-blind trial was performed on 29 mountaineers with at least moderate headache on the day of arrival at 4559 m. Fourteen subjects received 100 mg sumatriptan orally and 15 subjects received placebo. Before treatment there were no significant differences between groups regarding rate of ascent, duration and severity of headache, and acute mountain sickness score. All 6 female subjects were randomly assigned to placebo. Absolute values and the reduction of headache scores 1, 3, and 12 h after the administration of sumatriptan did not differ between treatment groups, but headache scores tended to be lower with sumatriptan after 1 or 3 h when compared with placebo. Considering only male mountaineers, there was a significant decrease of headache scores after 1 and 3 h. Because there was only a minor transient amelioration of high altitude headache with sumatriptan, we conclude that 5-HT1 receptors do not play a major role in the pathophysiology of high altitude headache.
