INTRODUCTION: Migraine is one of the commonest diseases of clinical practice. OBJETIVE: To compare the analgesic effect of dipyrone to metoclopramide in the relief of pain. METHOD: We conducted a pilot randomized study comparing intravenous dipyrone to intravenous metoclopramide in 27 patients presenting acute crisis of migraine. The primary end point was to compare reduction of intensity of pain up to 2 hours, as well as the development of collateral effects. RESULTS: The groups had similar ages, but there were difference between the sexes. In men, metoclopramide reduced pain in 80.0% compared with 55.0% from dipyrone (p=0.052). In women, there was a reduction of 65.0% with metoclopramide and 71.2% with dipyrone (p=0.748). The small number of patients in the study might have influenced these results. Significant collateral effects were not found. CONCLUSION: There was no difference about the intensity of pain reduction neither about the development of collateral effects comparing dipyrone to metoclopramide.
