Tolfenamic acid decreases migraine recurrence when used with sumatriptan.
Although sumatriptan is an effective drug for the treatment of acute migraine attacks, recurrence has been cited as an important limitation for its use. Tolfenamic acid is also effective in the acute treatment of migraine attacks. We studied the recurrence rate of migraine attacks with the use of sumatriptan plus tolfenamic acid among patients who presented frequent recurrence with sumatriptan. Fifty migraineurs were retrospectively studied, all having treated at least 10 attacks with 100 mg P.O.; sumatriptan was effective in at least eight of them. The patients also presented recurrence in less than 24 h in at least five of the treated attacks. We then used sumatriptan 100 mg plus tolfenamic acid 200 mg P.O. during the first 60 min of the attack; 240 attacks were treated and there was recurrence in 57 (23.8%). With sumatriptan alone, 5 out of 8 attacks (62.5%) presented recurrence. We therefore conclude that the combination sumatritpan plus tolfenamic acid is effective in reducing the recurrence rate from 5 of 8 (62.5%) to 1.19 of 5 (23.8%). Further prospective studies with a double-blind design and a higher number of treated attacks are necessary to confirm these initial observations.
