Protocol summary

Study aim
The aim of this study is to evaluate the efficacy and tolerability of melatonin compared to amitriptyline in the prevention of migraine headaches in children aged 5 to 15 years who presented with recurrent migraine to the pediatric neurology clinic of Imam Hossein Hospital during the year 2025.
Design
This study is a randomized, single-blind, parallel-group clinical trial designed to compare the efficacy and tolerability of melatonin versus amitriptyline for migraine prevention in children aged 5 to 15 years
Settings and conduct
The study will be conducted at the Pediatric Neurology Clinic of Imam Hossein Hospital, affiliated with Isfahan University of Medical Sciences. Eligible children visiting the clinic during 2025 (1404) will be enrolled after obtaining informed consent. Participants will be randomized into melatonin and amitriptyline groups using block randomization. The intervention will last for 12 weeks, with biweekly follow-up visits conducted by a pediatric research assistant.
Participants/Inclusion and exclusion criteria
Inclusion Criteria: Children aged 5–15 years with migraine (with/without aura) per ICHD-II, ≥1 attack/week, PedMIDAS >10, and no prior prophylactic treatment. Exclusion Criteria: Secondary headache, systemic illness, drug allergy, epilepsy or complicated migraine, psychiatric disorders, >4 analgesic doses/week, prior prophylaxis (except study meds), or lack of consent.
Intervention groups
Intervention Group 1: Melatonin Children in this group will receive oral melatonin 3 mg once nightly for a duration of 12 weeks. Intervention Group 2: Amitriptyline Children in this group will receive oral amitriptyline at a dose of 1 mg/kg once nightly for a duration of 12 weeks.
Main outcome variables
•Monthly frequency of migraine attacks •Headache severity (based on Visual Analog Scale) •Migraine-related disability score (PedMIDAS)

Scientific title
A Comparative Study on the Efficacy of Amitriptyline and Melatonin in the Preventive Treatment of Migraine in Children referred to Imam Hossain Hospital in 20205
Public title
A study on the effects of melatonin and amitriptyline on the severity and frequency of migraine headaches in children
Purpose
Treatment
Inclusion/Exclusion criteria
Inclusion criteria:
1.Age between 5 and 15 years 2.Diagnosis of migraine headache (with or without aura) based on the second edition of the International Classification of Headache Disorders (ICHD-II), confirmed by a pediatric neurologist 3.Experiencing at least one headache episode per week 4.Having moderate to severe migraine-related disability, defined as a PedMIDAS score >10 5.No use of any migraine prophylactic medications prior to enrollment in the study
Exclusion criteria:
1.Children with secondary headaches or systemic diseases (e.g., renal or hepatic failure, cardiac, hematologic, or endocrine disorders), based on physical examination and paraclinical findings (e.g., lab tests or neuroimaging if increased intracranial pressure is suspected) 2.Children or parents unwilling to participate in the study 3.Children with a history of drug allergy 4.Children with epilepsy or complex migraine 5.Children showing severe and uncontrolled adverse effects to melatonin or amitriptyline 6.Children receiving other migraine prophylactic drugs (except melatonin or amitriptyline) 7.Children with migraine and significant psychiatric comorbidities (e.g., depression or ADHD) who use analgesics more than 4 times per week

Randomization (investigator's opinion)
Randomized
Randomization description
Block randomization will be used, with 14 blocks of 4 participants each. The randomization process will be performed by a researcher not involved in the clinical management of participants. Both participants and the nurse administering the medication will be aware of group assignment, but the data analyst will remain blinded. Medications will be pre-coded, packed, and labeled prior to the study. At the time of assignment, the nurse will provide the medication package to the pediatric neurologist, who will calculate the appropriate dosage based on the child’s weight. Outcome assessment will be performed by a research assistant who is blinded to group allocation.
Blinding (investigator's opinion)
Single blinded
Blinding description
In this study, only the outcome assessor and the data analyst are blinded. Medications are pre-coded and packed by an independent individual before the study begins. Clinical assessments are performed by a research assistant who is unaware of the treatment allocation. Data will also be provided to the statistician without group identifiers to ensure blinded statistical analysis.
