Comparative Efficacy of Flunarizine and Propanolol in Pediatric Migraine

Despite the clinical use of flunarizine and propranolol, direct comparisons between these two drugs in children are scarce. This study aims to bridge that gap by evaluating their relative effectiveness and safety as prophylactic treatments for pediatric migraine, addressing a critical unmet need in current research. Considering the routine use of both drugs in clinical practice, the findings would help clinicians to choose the more convenient drug between flunarizine and propranolol as preventive therapy for migraine in their local settings.
