Diclofenac with or without an antiemetic for acute migraine headaches in adults
Abstract
BACKGROUND: This review is an update of a previously published review in Issue 2, 2012 (Derry 2012a). Migraine is a common, disabling condition and a burden for the individual, health services and society. Many sufferers choose not to, or are unable to, seek professional help and rely on over-the-counter (OTC) analgesics. Diclofenac is an established analgesic, and new formulations using the potassium or epolamine salts, which can be dissolved in water, have been developed for rapid absorption, which may be beneficial in acute migraine. Co-therapy with an antiemetic should help to reduce the nausea and vomiting commonly associated with migraine.
OBJECTIVES: To determine the efficacy and tolerability of diclofenac, alone or in combination with an antiemetic, compared to placebo and other active interventions in the treatment of acute migraine headaches in adults.
SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, the Oxford Pain Relief Database, ClinicalTrials.gov, and reference lists for studies through 27 September 2011 for the original review and 15 February 2013 for the update.
SELECTION CRITERIA: We included randomised, double-blind, placebo-controlled or active-controlled studies, or both, using self administered diclofenac to treat a migraine headache episode, with at least 10 participants per treatment arm.
DATA COLLECTION AND ANALYSIS: Two review authors independently assessed trial quality and extracted data.…
