A comparative study on the effectiveness of topiramate and propranolol in patients with migraine with aura.

Background: Migraine is considered as one of the most common and disabling diseases of the nervous system that has a great impact on quality of life (QOL) and a little risk of neurologic complications such as stroke. Migraine aura is known to be the result of cortical spreading depression and is associated with higher risk of this complication. Thus, the present study was conducted with the aim to compare the effects of topiramate as an antiepileptic, and propranolol in patients with migraine with aura. Methods: The present randomized clinical trial was conducted on patients with migraine with aura referred to the neurology clinic of Golestan Hospital, Ahvaz, Iran, in the period of 2019-2020. The patients were randomized into two groups and received either topiramate or propranolol. The Migraine Disability Assessment Scale (MIDAS) score was evaluated before and at the end of three months after initiating the treatment. Results: Reduction in the MIDAS score in patients taking topiramate (-16.94) was greater than that in the propranolol group (-14.5), but this difference was not statistically significant (P > 0.005). No significant relationship was found between gender and changes in the MIDAS score after the treatment of both groups (P > 0.050). However, the changes in the MIDAS score were greater in younger patients, and this relationship was statistically significant (P < 0.050). Conclusion: There was no significant difference in the efficacy of topiramate and propranolol in patients with migraine with aura. No significant relationship was found between gender and changes in the MIDAS score after the treatment in both groups, but the reduction in the MIDAS scores was significantly higher in younger patients of both groups.
