RT Journal Article SR Electronic T1 Migraine: pharmacotherapy in the emergency department JF Journal of Accident & Emergency Medicine JO Arch Emerg Med FD BMJ Publishing Group Ltd and the British Association for Accident & Emergency Medicine SP 241 OP 245 DO 10.1136/emj.17.4.241 VO 17 IS 4 A1 Anne-Maree Kelly YR 2000 UL http://emj.bmj.com/content/17/4/241.abstract AB Migraine can be a disabling condition for the sufferer. For the small number of patients who fail home therapy and seek treatment in an emergency department, there are a number of therapeutic options. This paper reviews the evidence regarding the effectiveness and safety of the following therapies: the phenothiazines, lignocaine (lidocaine), ketorolac, the ergot alkaloids, metoclopramide, the “triptans”, haloperidol, pethidine and magnesium. Based on available evidence, the most effective agents seem to be prochlorperazine, chlorpromazine and sumatriptan, each of which have achieved greater then 70% efficacy in a number of studies.
