Sumatriptan in the acute treatment of migraine.

Abstract

Sumatriptan is a selective 5-HT1-like agonist, which is effective in the treatment of migraine and cluster headache. It has been rigorously assessed in clinical trials involving over 7000 patients who have treated over 35,000 migraine attacks. Both subcutaneous and oral sumatriptan provide a high level of efficacy with 86% of patients obtaining relief after a single 6 mg injection (at 2 h) and 75% after 100 mg oral sumatriptan (4 h), compared with up to 37% in the placebo-treated group (P < 0.001). The onset of effect is rapid, occurring 10 min after injection and 30 min after the tablet. Oral sumatriptan (100 mg) has been evaluated against ergotamine, 2 mg, plus caffeine, 200 mg (as Cafergot); and against aspirin, 900 mg, plus metoclopramide, 10 mg. Headache relief was superior in sumatriptan-treated patients; 66% obtaining relief at 2 h, compared with 48% on Cafergot (P < 0.001). The percentage of patients obtaining complete relief of headache (Grade 0, no pain) was significantly higher with sumatriptan (40%) than with Cafergot (14%) at 2 h. Associated symptoms such as nausea, vomiting and photophobia are effectively relieved by sumatriptan, whereas Cafergot provoked nausea and vomiting in a proportion of patients. Headache relief with sumatriptan was also superior to that seen with aspirin plus metoclopramide. Sumatriptan was as effective in the relief of accompanying nausea and vomiting as aspirin plus metoclopramide. The efficacy of sumatriptan is maintained after repeated long-term use; over a six-month period efficacy was comparable in the first and last attacks, regardless of how many attacks were treated.(ABSTRACT TRUNCATED AT 250 WORDS)
