title: Efficacy and safety of intravenous acetylsalicylic acid lysinate compared to subcutaneous sumatriptan and parenteral placebo in the acute treatment of migraine. A double-blind, double-dummy, randomized, multicenter, parallel group study. The ASASUMAMIG Study Group.
abstract: Two-hundred-and-seventy-eight patients with acute migraine attacks with or without aura were treated in 17 centers with 1.8 g lysine acetylsalicylate i.v. (Aspisol; = 1 g acetylsalicylic acid), 6 mg sumatriptan s.c. or placebo using a double-blind, double-dummy, randomized, multicenter parallel group study design. Two-hundred-and-seventy-five of them fulfilled the criteria for efficacy analysis, corresponding to 119 patients treated with lysine acetylsalicylate (L-ASA), 114 with sumatriptan and 42 with placebo injections. Both treatments were highly effective compared to placebo (p < 0.0001) in decreasing headache from severe or moderate to mild or none (verbal rating scale, VRS, placebo = 23.8%). Sumatriptan showed a significantly (p = 0.001) better response (91.2%) compared to L-ASA (response 73.9%). Of the patients in the L-ASA-group, 43.7% were pain-free after 2 h; 76.3% after sumatriptan and 14.3% after placebo. It took patients on average 12.6 (L-ASA), 8.2 (sumatriptan), and 19.4 h (placebo) to be able to work again. There was no significant difference between treatment groups in recurrence of headache in responders within 24 h (18.2% L-ASA, 23.1% sumatriptan, 20% placebo). Accompanying symptoms (nausea, vomiting; photophobia, phonophobia, and visual disturbances) improved with both verum treatments to a similar extent. L-ASA was significantly better tolerated than sumatriptan (adverse events L-ASA 7.6%, sumatriptan 37.8%). In conclusion, subcutaneous sumatriptan and lysine acetylsalicylate i.v. are effective treatments for patients suffering from migraine attacks. Sumatriptan is more effective, but resulted in more adverse events.
