Objective:To evaluate the efficacy and safety of Chinese herbal medicines(CHMs)combined with chemical drugs for the treatment of Alzheimer's disease(AD).Materials and Methods:Databases were searched to retrieve randomized controlled trials(RCTs)of CHMs combined with tacrine,galantamine,rivastigmine,donepezil,or memantine,following strict inclusion and exclusion *** research papers published in English,Chinese,and Japanese were *** primary outcome was the mini-mental state examination(MMSE)score and the secondary outcomes were AD assessment scale cognitive subscale(ADAS-Cog)score and safety ***-analysis was carried out using Rev Man 5.3 and subgroup analysis was conducted to identify the sources of ***:A total of 15 RCTs with 1386 participants were included in this *** donepezil was used in the retrieved ***-analyses showed that the combination of CHMs with donepezil led to significant improvement in the MMSE score(Z=9.45;P<0.00001;weighted mean difference[WMD]=2.68,95%confidence interval[CI]:2.12-3.24)and a significant decrease in the ADAS-Cog score(Z=5.53;P<0.00001;WMD=-3.79;95%CI:-5.13--2.44).Safety evaluation demonstrated that these combination treatments relieved adverse events such as insomnia(risk ratio[RR]=0.20,95%CI:0.06-0.68;P=0.01)and hive(RR=0.10;95%CI:0.01-0.73;P=0.02).Conclusions:The combination of CHMs with a chemical drug like donepezil led to significant improvements in patient cognition as well as a better safety profile when compared to the application of a chemical drug alone.
