Meta-analysis of the efficacy and safety of naproxen sodium in the acute treatment of migraine
Abstract
OBJECTIVE: To assess the efficacy and safety of naproxen sodium in the treatment of acute migraine attacks.
BACKGROUND: Non-steroidal anti-inflammatory drugs including naproxen sodium have been used in treating migraine attack. A number of clinical trials of naproxen sodium in migraine have been reported. However, it remains to be established whether naproxen sodium unequivocally offers clinical benefits taken into account the desired outcomes in acute migraine therapy as recommended by the International Headache Society.
METHODS: Clinical trials were identified through electronic searches (MEDLINE, EMBASE, EBM review, and the Cochrane Library) up to June 2009 and historical searches of relevant articles. Studies were included in the meta-analysis if they were (1) double-blind, randomized, placebo-controlled trials that evaluated naproxen sodium tablet in moderate or severe migraine attacks in adult patients, and (2) reporting the efficacy in terms of headache relief, pain-free, relief of migraine-associated symptoms, sustained headache relief, sustained pain-free, or headache recurrence. Data extraction and study quality assessment were performed independently by 2 investigators. Disagreements were resolved by a third investigator. Treatment effects and adverse effects were expressed as risk ratio. A random effects model was used when significant heterogeneity existed, otherwise the fixed effects model was performed.
RESULTS: We identified 16 published randomized controlled…
