Comparison of the Effectiveness of First-line Preventive Treatment of Migraine in Primary Care

This study, which is aimed at comparing the effectiveness of the most frequently used drugs in the first line in primary care for the preventive treatment of migraine (amitriptyline, flunarizine, topiramate and propranolol), is a multicentre, pragmatic, parallel group, open randomised trial. Adults (≥18) candidates for preventive treatment for migraine; those with a frequency of ≥4 monthly migraine days, and who agree to participate in the clinical trial, will be randomised to one of the 4 groups. Sample: 460 patients. The primary outcome will be the reduction in monthly migraine days, comparing amitriptyline, flunarizine and topiramate with propranolol.
