OBJECTIVES: We evaluated the effectiveness of combination treatment using sumatriptan plus metoclopramide versus sumatriptan alone for the treatment of acute migraine. The patients who were treated had failed to respond to triptans in the past despite adequate doses on at least 2 separate trials of the same triptan or 2 trials involving different triptans. BACKGROUND: There is limited evidence that dopaminergic antagonists may benefit the migraineur by relieving migraine pain and associated symptoms. The exact mechanism of action in migraine is unknown. The postulated action is the inhibition of dopaminergic overactivity. A dopaminergic antagonist, metoclopramide, may improve the efficacy of a 5-HT1B/1D agonist, sumatriptan. METHODS: In this double-blind, randomized, crossover study, 16 adult migraineurs fulfilling International Headache Society (IHS) criteria for migraine with or without aura who had failed to receive adequate relief from triptans treated one migraine with each treatment: sumatriptan 50 mg plus metoclopramide 10 mg or sumatriptan 50 mg plus placebo to match metoclopramide. Patients treated their migraines when they were moderate or severe in intensity and recorded pain severity and symptoms prior to treatment and 30, 60, 90, and 120 minutes and 24 hours after treatment. RESULTS: Thirteen women and 3 men (mean age, 40 years) completed the study; ie, treated 2 migraines (a total of 32 migraines), one attack with each treatment. Meaningful relief was attained in 10 (63%) of 16 migraines treated with the combination of sumatriptan 50 mg plus metoclopramide 10 mg compared with 5 (31%) of 16 migraines treated with sumatriptan 50 mg plus placebo. Headache response (moderate or severe to mild or no pain at 2 hours) was achieved in 7 (44%) of 16 migraines with the combination of sumatriptan 50 mg plus metoclopramide 10 mg compared with 5 (31%) of 16 migraines treated with sumatriptan 50 mg plus placebo. There did not appear to be a difference between treatment groups with respect to associated symptoms. The combination of sumatriptan 50 mg plus metoclopramide 10 mg was well tolerated. CONCLUSIONS: Combining sumatriptan with metoclopramide provided relief in some migraineurs who failed to achieve adequate relief with a triptan alone. It remains unknown whether initiating therapy when pain was mild or using a higher dose of sumatriptan (ie, 100 mg) would have provided additional benefit. Further studies are indicated.

STUDY OBJECTIVE: We test the hypothesis that intravenous magnesium sulfate is an effective adjunctive medication for treatment of acute migraine. METHODS: In this randomized, double-blind, placebo-controlled trial, adults presenting to 2 urban emergency departments with headache meeting International Headache Society criteria for acute migraine received either 20 mg of intravenous metoclopramide plus 2 g of intravenous magnesium sulfate or 20 mg of intravenous metoclopramide plus a placebo of intravenous saline solution at 15-minute intervals for a maximum of 3 doses or until pain relief occurred. At 0, 15, 30, and 45 minutes, patients recorded pain intensity using a standard visual analog scale (VAS). The primary study end point was the between-group difference in pain improvement when initial and final VAS scores were compared. RESULTS: Of 44 patients enrolled (21 randomized to metoclopramide plus magnesium and 23 to metoclopramide plus placebo), 42 (95%) were women. Baseline features were comparable in both groups. Each group experienced a more than 50-mm improvement in VAS score during the study. However, this improvement was smaller in the magnesium group for the primary end point (16-mm difference favoring placebo [95% confidence interval (CI) -2 to 34 mm]), as was the proportion with normal functional status at their final rating (36% absolute difference also favoring placebo [95% CI 7% to 65%]). Using a 50% reduction in pain to dichotomize VAS scores, the number needed to harm with magnesium plus metoclopramide versus metoclopramide alone is 4 patients (95% CI 2 to 36). CONCLUSION: Although this result was unexpected, our data suggest that the addition of magnesium to metoclopramide may attenuate the effectiveness of metoclopramide in relieving migraine. Countertherapeutic cerebral vasodilatation caused by magnesium is a plausible, although unproven, explanation for this finding. Because of the preponderance of women in our trial, these data may not be generalizable to men.

A prospective double-blind study of nasal sumatriptan versus IV ketorolac in migraine.

We conducted a study to compare the efficacy in migraine headache of nasal sumatriptan and intravenous ketorolac. The study was a prospective, double-blind study done with a convenience sample of 29 patients presenting to the emergency department (ED) with acute migraine. Patients received either 20 mg of nasal sumatriptan or 30 mg of intravenous ketorolac. Patients scored the severity of their headache on a 100-mm visual analog scale (VAS) of pain prior to medication, and again 1 hour after medication. Differences between initial and 1-hour scores were analyzed. Before treatment, no difference existed between the groups in the intensity of headache. One hour after medication, the sumatriptan group had a decrease in pain score of 22.937 mm and the ketorolac group a decrease of 71.462 mm on the VAS. The decrease in pain score with ketorolac was significantly greater than that with sumatriptan (P < 0.001). The study therefore showed that both sumatriptan and ketorolac effectively reduced the pain associated with acute migraine headache, but that intravenous ketorolac produced a greater reduction in pain than did nasal sumatriptan.

TREATMENT AND ETIOLOGY OF HEADACHE IN THE ED
Inhalation of High-flow Oxygens as a Treatment for Migraine Headache in the Emergency Department

ABSTRACT
Objective: Migraine headache is a common complaint in the Emergency Department. We hypothesized that inhalation of one hundred percent oxygen for thirty minutes would cause a clinically significant (25%) reduction of pain for patients with migraine headache. Methods: This study was a prospective, randomized, controlled, double-blinded trial using high-flow inhaled oxygen as the treatment group and inhaled air as the control group. It was conducted between December 2001 and April 2002 in the ED of a military hospital. A convenience sample was enrolled into the study using a computer generated randomization scheme. Inclusion criteria were all patients 18 to 65 years old with a previous diagnosis of migraine headaches who presented to the ED complaining of a "typical migraine headache". Exclusion criteria included: patients triaged as "urgent" or "emergent", patients with altered mental status, febrile patients, and patients with COPD. A visual analog scale (VAS) was used to rate headache pain before and after treatment. The change in pain score as measured by the VAS (in mm) was assessed by a two factor repeated measures analysis of variance (ANOVA). Change in VAS from before intervention to after intervention between the Air and Oxygen groups was the test of interest. Analysis of covariance (ANCOVA) was also used to compare VAS scores after intervention adjusted for VAS scores before intervention. Results: Forty-six patients completed the study, with 23 in each group. The Air group recorded a mean pain level of 84.7mm +/- 13.2mm SD on the VAS before intervention and 81.3mm +/- 15.3mm SD after intervention. The Oxygen group showed a mean of 76.1mm +/- 15.5 SD prior to intervention and a mean of 60.4mm +/- 29.4mm SD after intervention. The Oxygen group had, on average a 21% decrease in pain compared to a 4% decrease for the Air Group (p = 0.031 by ANCOVA). Conclusion: Inhalation of high-flow oxygen caused a statistically significant reduction in the pain of migraine headache.
