About this study

Investigators will enroll 600 migraine patients who are diagnosed according to ICHD3-beta criteria in our study and will use a questionnaire to detect their demographic and clinical features (disease duration, attack frequency, and duration, pain intensity assessed by the visual analogic scale and we have two groups the first group will include 300 patients and will receive 100mg zonisamide daily and Acetaminophen 500-1000 mg in acute attack, and the second group will receive topiramate100 mg per day and Acetaminophen 500-1000 mg in acute attack for at least three months. Investigators will assess The number of migraine days after three months of treatment and the percentage of patients who achieved ≥ 50% reduction in the monthly headache days frequency compared to the baseline frequency. HIT-6 score reduction in each group after three months of treatment. The safety of lacosamide was evaluated by monitoring and documenting treatment-emergent adverse events (TEAE) in patients through regular follow-up procedures for three months.

Treatment and study plan

Zonisamide 50 MG

Drug

The arm will include 300 migraine patients diagnosed according to ICHD3-beta criteria. We will assess The change in migraine days per 28 days, the number of migraine days after three months of treatment, and the percentage of patients who achieved ≥ 50% reduction in the monthly headache days frequency compared to the baseline frequency (14). HIT-6 score reduction in each group after three months of treatment. The safety of zonisamide was evaluated by monitoring and documenting treatment-emergent adverse events (TEAE) in patients through regular follow-up procedures for three months.

Other names: group A

Topiramate 50 MG

Drug

The arm will include 300 migraine patients diagnosed according to ICHD3-beta criteria. We will assess The change in migraine days per 28 days, the number of migraine days after three months of treatment, and the percentage of patients who achieved ≥ 50% reduction in the monthly headache days frequency compared to the baseline frequency (14). HIT-6 score reduction in each group after three months of treatment. The safety of topiramate was evaluated by monitoring and documenting treatment-emergent adverse events (TEAE) in patients through regular follow-up procedures for three months.

Other names: group B

Primary outcomes

  1. The change in migraine days per 28 days

    Time frame: 28 days

    The investigators will assess the change in migraine days per 28 days in each group.

Secondary outcomes

  1. The total number of migraine days after three months of treatment

    Time frame: 3 months

    The investigators will assess the total migraine days after three months of regular use of 100 mg zonisamide twice daily and Acetaminophen 500-1000 mg in acute attack or topiramate (100 mg once daily) and Acetaminophen 500-1000 mg in acute attack alone.

  2. The percentage of patients who achieved ≥ 50% reduction in the monthly migraine days frequency compared to the baseline frequency.

    Time frame: 3 months

    We will assess The percentage of patients who achieved ≥ 50% reduction in the monthly headache days frequency compared to the baseline frequency in each group

  3. HIT-6 score absolute reduction in each group after three months of treatment

    Time frame: 3 months

    The investigators assessed the absolute reduction in HIT6 score, the Headache Impact Test-6 (HIT-6) assessed the burden of headache in each group; the HIT-6 consists of six items: pain, social functioning, role functioning, vitality, cognitive functioning, and psychological distress, the patient answers each of the six related questions using one of the following five responses: "never", "rarely", "sometimes", "very often," or "always." These responses are summed to produce a total HIT-6 score that ranges from 36 to 78, where a higher score indicates a greater impact of headache on the daily life of the respondent. It has four impact grades: little-to-no impact (HIT-6 score: 36-49), moderate impact (HIT-6 score: 50-55), substantial impact (HIT-6 score: 56-59), and severe impact (HIT-6 score: 60-78)

  4. The safety of lacosamide was evaluated by monitoring treatment-emergent adverse events (TEAE) for three months.

    Time frame: 3 months

    The safety of zonisamide was evaluated by monitoring and documenting treatment-emergent adverse events (TEAE) in patients through regular follow-up procedures for three months.
