Abstract:【Objective】 To evaluate the clinical beneficial and adverse effects of Butylphthalide and Sodium Chloride Injection combined with dual antiplatelet therapy in treating progressive cerebral infarction. 【Methods】 A total of 86 patients with acute progressive cerebral infarction were randomly divided into two groups, i.e. treatment group and control group. The treatment group was treated with Butylphthalide and Sodium Chloride Injection combined with Aspirin and Clopidogrel, while the control group was treated by Aspirin and Clopidogrel. The clinical nervous function defect degree and activities of daily living were evaluated by the NIHSS and Barthel index respectively before treatment and on the 8th and 15th d after treatment. The adverse reactions of both groups were recorded and monitored. 【Results】 The NIHSS score was significantly reduced while the Barthel score was significantly increased in both groups on the 15th d after treatment compared to that before treatment (P < 0.05). On the 8th d after treatment, the NIHSS score was obviously decreased but the Barthel score was greatly improved in the treatment group compared to that before treatment (P < 0.05). Compared with the control group, the NIHSS score was significantly decreased and the Barthel score was significantly increased in the treatment group on the 8th and 15th d after treatment (P < 0.05). There was no obvious adverse reaction in either group. 【Conclusions】 Treatment by Butylphthalide and Sodium Chloride Injection combined with Aspirin and Clopidogrel is a safe and effective therapy for progressive cerebral infarction.
