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). ⋯ 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)
