Cost-minimization Analysis of Ginkgolide Injection versus Butylphthalide Injection in the Treatment of Ische- mic Stroke of Large-artery Atherosclerosis / 中国药房

ABSTRACT

OBJECTIVE：To eval uate therapeutic effic acy，safety and economical efficiency of Ginkgolide injection versus Butylphthalide injection in the treatment of ischemic stroke. METHODS ：Among the GISAA of Ginkgolide injection in the treatment of ischemic stroke of large-artery atherosclerosis ，106 patients who were given Ginkgolide injection+Asprin enteric-coated tablets but did not use butylphthalide in any dosage in previous trial group were selected as ginkgolide group ；56 patients who were given Butylphthalide injection+Ginkgolide injection+Asprin enteric-coated tablets in previous placebo group were selected as control group. The effects ，safety and economical efficiency were compared between 2 groups. Effect indexes included recurrence rate ， mortality，NIHSS score ，modified Rankin score （mRS），Barthel index and comprehensive efficacy. The safety indexes included incidence of bleeding event and adverse event during treatment. Cost-minimization analysis was used for economic evaluation. RESULTS：There was no statistical difference in recurrence rate ，mortality，NIHSS score ，the proportion of subjects with mRS 0-2，Barthel index ，comprehensive efficacy and the incidence of adverse event between 2 groups on 28th day after treatment （P＞ 0.05）. NIHSS score of ginkgolide group was better than that of control group on 7th and 14th day （P＜0.05）. Results of cost-minimization analysis showed that total cost of ginkgdide group was （13 768.19±4 981.54）yuan on 14th day of treatment ， which was significantly lower than （22 578.52±7 523.23）yuan of control group （P＜0.01）. The results of sensivity analysis indicated that the minimum lost analysis was stable. CONCLUSIONS ：For the treatment of ischemic stroke ，ginkgolide+aspirin is similar to butylphthalide+aspirin in improving clinical outcome and safety of 28 days，but is better than it in short-term efficacy of improving neurological deficit ， and better short-term economical efficiency.
