title: Defining optimal dosing for sumatriptan tablets in the acute treatment of migraine.
abstract: Oral sumatriptan, which is a well tolerated, effective acute treatment for migraine, and is selectively available in different countries in 100 mg, 50 mg, and 25 mg tablets. The first large dose-ranging study compared the 100 mg dose to higher doses (200 mg and 300 mg) and found it to be just as efficacious and better tolerated. The first studies comparing the 100 mg dose to lower doses (25 mg and 50 mg) found them all to be similar in effectiveness and tolerability. However, a larger definitive study found that the 100 mg and 50 mg doses offered better efficacy than the 25 mg dose, whereas the 25 mg and 50 mg doses were better tolerated than the 100 mg dose. Thus the 50 mg dose appears to offer the best ratio of efficacy to tolerability. Many patients, though, prefer or require the 100 mg dose and tolerate it well. Allowed to select dosing themselves, patients tend to migrate to the 100 mg dose.
