Objective To systematically evaluate the efficacy and safety of extract of Ginkgo biloba preparations (EGb) for Alzheimer's disease. Methods A randomized controlled trial (RCT) of EGb for Alzheimer's disease was conducted on PubMed, Web of Science, Embase, CBM, CNKI, VIP and Wanfang databases from inception to October 29, 2019. Two evaluators independently screened the literature for quality evaluation, and RevMan 5.3.5 software was used for statistical analysis. Results A total of 21 RCTs were included, including 1 643 patients. Meta-analysis results showed:(1) Compared with citicoline, EGb can improve MMSE[MD=3.80, 95%CI(2.05, 5.55), P<0.000 1], ADL scores[MD=-3.30, 95%CI(-4.75, -1.85), P<0.000 01] and total effective rate[OR=3.69, 95%CI(1.87, 7.27), P=0.000 2] more effectively; (2) Compared with the use of only basic treatment or other drugs alone, the combination of EGb can improve MMSE[MD=2.68, 95%CI(2.35, 3.02), P<0.000 01], ADL score[MD=-3.48, 95%CI(-4.36, -2.60), P<0.000 01] and total effective rate[OR=3.50, 95%CI(1.09, 11.22), P=0.03] more effectively; (3) Compared with placebo or no intervention, EGb can effectively improve MMSE[MD=1.82, 95%CI(0.33, 3.32), P=0.02] and ADL scores[MD=-7.00, 95%CI(-10.93, -3.07), P=0.0005]; (4) Compared with donepezil monotherapy, the combination of donepezil and EGb can improve MMSE[MD=1.82, 95%CI(0.33, 3.32), P=0.02], ADL scores[MD=-4.29, 95%CI(-5.58, -2.99), P<0.000 01] and total effective rate[OR=2.95, 95%CI(1.42, 6.13), P=0.004] more effectively; (5) EGb has a significantly lower effect on the MMSE score[MD=-1.79, 95%CI(-2.39, -1.20), P<0.000 01] and total effective rate[OR=0.15, 95%CI(0.08, 0.30), P<0.000 01] than donepezil. Conclusions EGb are effective in the treatment of Alzheimer's disease, and there is no significant difference in adverse reactions.
