Propranolol versus topiramate in prophylaxis of migraines among children and adolescents: a randomized, double-blind clinical trial

Background Migraine is a common health problem in children and adolescents. This study compares the efficacy and safety of propranolol and topiramate in preventing migraine among children and adolescents.

Methods Seventy-six patients (10-18 years of age) with migraine without auras defined by the 2004 International Headache society criteria were included in a prospective double blind clinical trial were allocated to receive propranolol (0.5-2mg/kg per day) or topiramate (1-2mg/kg per day). The primary outcome measure was reduction in 50 % or more headache days in comparison to baseline headache frequency per month. Secondary outcome measures were headache related disability, migraine intensity and duration. Efficacy measures were recorded at the baseline and at 12 weeks of prophylactic treatment.

Results In this study total of 76 patients with mean age of 12.43 years were evaluated, 40 in the propranolol group and 36 in the topiramate group. At the 12-week, the percentage of patients who had a relative reduction of 50% or more in the number of headache days were 67.5% patients in the propranolol group and 75.0% patients in the topiramate group. The monthly migraine frequency, headache related disability, intensity and duration were significantly decreased in both the propranolol and topiramate groups when compared to the baseline. No significant difference was observed between these two groups in term of reduction of frequency, headache related disability, severity and duration of attack. Fatigue, hypotension and exercise induced asthma were main side effects in propranolol group and weight loss, fatigue and loss of appetite, paresthesias in topiramate group.

Conclusions Propranolol and topiramate were found effective and safe for the prevention of paediatric migraines.
