Primary Outcome Measures:
  • Change in number of headache days from baseline to month 3 after treatment. [ Time Frame: Baseline (4 weeks) and treatment period (12 weeks) ]
    This is a randomized, double-blind, placebo-controlled, parallel-group, multicenter study to evaluate the efficacy of melatonin 3 mg, amitriptyline 25 mg versus placebo in the prevention of migraine headaches. The study consists of 2 phases: Baseline Phase (4 weeks) and Double-Blind Phase (patients are randomized to receive melatonin, amitriptyline or placebo for a total of 12 weeks).

Secondary Outcome Measures:
  • Proportion of patients responding to treatment. Change from Baseline Phase to Double-Blind Phase in number of monthly migraine attacks, migraine intensity, migraine duration, analgesic use, weight (in kg), and tolerability reports. [ Time Frame: Baseline (4 weeks) and treatment period (12 weeks) ]

Enrollment: 192
Study Start Date: May 2010
Study Completion Date: December 2012
Primary Completion Date: December 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Melatonin
Melatonin 3 mg at bedtime
Drug: Melatonin
It will be administered Melatonin (3mg) at bed time, half an hour before the usual time of sleep of the patient.
Placebo Comparator: Placebo
Drug: Placebo
It will be administered placebo capsules, identical to Melatonin (3mg) and Amitriptyline (25 mg) patients will take the study medication at bed time
Active Comparator: Amitriptyline
Amitriptyline 25 mg
Drug: Amitriptyline
It will be administered Amitriptyline (25mg) once a day at bed time. Patients may keep their abortive treatment that they usually used. The drug will be encapsulated in a bottle of 30 capsules will be given to patients at every visit.

Detailed Description:
The investigators propose a study of patients with migraine (episodic) with or without aura, according to the criteria of the International Headache Society (IHS) 2004. This will be a randomized clinical trial, prospective, double-blind, placebo-controlled, comparing the efficacy of melatonin 3 mg and amitriptyline 25 mg for migraine prevention. The length of the inclusion of the study will be 24 months. This study's general objective is: to evaluate the effectiveness of melatonin in the preventive treatment of migraine and compare it to placebo and amitriptyline.

Ages Eligible for Study:   18 Years to 65 Years   (Adult)

  • Women who began taking oral contraceptives or who switched their oral contraceptive regimen in the 6 months prior to the start of the study.
  • Allergy or known hypersensitivity to study medication or its components.
  • Participation in another clinical study one month before inclusion.
