Method: 2120 migraineurs took flunarizine (5~10 mg, qd) orally for 12 weeks.The intensity of headache (VAS),frequency of headache,dosage of flunarizine, adverse events and blood pressure were assessed before treatment and 4, 8, 12 weeks after treatment. Result:Significant difference existed among before treatment and 4, 8, 12 weeks after treatment in VAS, frequency of headache and dosage of flunarizine (all P<0.05). However, the blood pressure showed no significant difference among different time (all P>0.05).Severe adverse events were not found. Conclusion:Flunarizine is safe and effective for the prophylaxis treatment of migraine.
