A randomized trial comparing amitriptyline versus topiramate for the prophylaxis of chronic daily headache in pediatric patients

摘要

Objective: the goal of this prospective and double-blind study was to compare the efficacy of amitriptyline and topiramate for the prevention of pediatric chronic daily headache (CDH). Research design and methods: fifty-seven children (aged 9-16 yr) diagnosed with CDH were randomly assigned to two groups: group A (n = 29 patients) received amitriptyline 0.5 mg/kg/d and group B (n = 28 patients) received topiramate 25 mg/d increasing up to 100 mg/d according to patient response. Treatment response was monitored for at least 4 months. Results: fifty-five percent of the patients in group A responded to amitriptyline and 61% of patients in group B responded to topiramate as defined by a reduction of more than 50% in monthly headache frequency. There was no significant difference in responder rate or adverse event rate between the two groups (p > 0.05). By the end of the 4-month treatment period, there were no significant differences in the final average severity and monthly frequency of headaches betweenatment groups. Conclusion: these results suggest that the efficacy and tolerability of topiramate is equivalent to that of amitriptyline for reducing the frequency of headache in pediatric CHD patients.
