Randomized Controlled Trial Multicenter Study Comparative Study
Evaluation of the efficacy of intravenous acetaminophen in the treatment of acute migraine attacks: a double-blind, placebo-controlled parallel group multicenter study.
The efficacy of intravenous acetaminophen (1000mg) in the treatment of acute migraine attacks as an alternative to parenteral application of lysine acetylsalicylate or triptans was investigated, using a multi-center, randomized, double-blind, placebo controlled study design. Migraine diagnosis was made according to the International Headache Society Classification. Sixty patients were included in three headache outpatient centers (Neurology Departments of the Universities of Regensburg, Münster and München). ⋯ Out of these, 3 patients in the acetaminophen and 4 patients in the placebo group were painfree. After 24hours 86% of the patients reported pain relief: 24 treated with acetaminophen and 27 treated with placebo. The results indicate, that 1000mg intravenous acetaminophen is not superior to placebo in treating severe acute migraine attacks.
