      <i_freetext>Intervention 1: After the eligibility criteria will be applied, 112 chronic migraineurs will be selected and randomly allocated to placebo or intervention groups. Upon admission, a headache questionnaire will be given to all patients to fill out the characteristics of  headaches experienced in the past month (including severity and duration of each attack). Also they will be asked not to take any medication for migraine prophylaxis and or analgesic drugs. Patients in the intervention group (n=56) will be instructed to take a tablet of Lisinopril 5 mg per day at the first week and to use 1 tablet each 12-hour thereafter (2 tablets per day from the second week to the end of the 12th week). At the same time from the beginning of the study, 4 capsules of Celebrex 100-milligram per day, thereafter the dosage will be reduced by 100-mg (1 capsule) each 5-day to zero over the first 20 days of the study. In the second week of the study the patients will be physically examined. Duration of the study will be 12 weeks and headache characteristics as well as drug response and quality of life will be assessed at the end of each month during the study. Intervention 2: After the eligibility criteria will be applied, 112 chronic migraineurs will be selected and randomly allocated to placebo or intervention groups. Upon admission, a headache questionnaire will be given to all patients to fill out the characteristics of headaches experienced in the past month (including severity and duration of each attack). Also they will be asked not to take any medication for migraine prophylaxis and or analgesic drugs. Patients in the placebo group (n=56) will be instructed to take a tablet of placebo per day at the first week and to use 1 tablet each 12-hour thereafter (2 tablets per day from the second week to the end of the 12th week). At the same time from the beginning of the study, 4 capsules of Celebrex 100-milligram per day, thereafter the dosage will be reduced by 100-mg (1 capsule) each 5-day to zero over the first 20 days of the study. In the second week of the study the patients will be physically examined.
