    Abstract:
    OBJECTIVE: To determine the prophylactic effect of OPFAϖ-3 in migraine. SUBJECTS AND METHODS: This was a prospective, experimental, controlled, double-blind, and with comparison groups study. Sixty patients diagnosed with chronic migraine, according to the criteria of the International Classification of Headache Disorders, Third Edition (beta version) (ICHD-3β), were prophylactically treated with amitriptyline. They were divided into two equal groups: in group 1, prophylaxis was associated with OPFAϖ-3 and in group 2 with placebo. After 60 days, both groups were assessed by a second researcher. RESULTS: Of the 60 patients with chronic migraine, only 51 patients (15 men and 36 women) completed the treatment. The group that received OPFAϖ-3 consisted of 27 (52.9%) patients (six men and 21 women), while the control group was equal to 24 (47.1%) patients (nine men and 15 women). These differences were not significant (χ2 = 1.428; P = 0.375). In 66.7% (18/27) of the patients who used OPFAϖ-3, there was a reduction of more than 80.0% per month in the number of days of headache, while in the control group, the same improvement occurred in 33.3% (8/24) of patients. This difference was significant (χ2 = 5.649; P = 0.036). CONCLUSIONS: Polyunsaturated omega 3 fatty acids (OPFAϖ-3) are useful for prophylaxis of migraine attacks.
