Efficacy and safety of Jianzhong decoction in treating peptic ulcers: a meta-analysis of 58 randomised controlled trials with 5192 patients.

BACKGROUND

Jianzhong decoction is widely used to treat peptic ulcers; however, due to lack of systematic evaluations, its clinical efficacy remains controversial. We performed meta-analysis to evaluate the efficacy and safety of Jianzhong decoction in treating peptic ulcers.

METHODS

Studies were systematically retrieved from PubMed, Embase, Cochrane library, China National Knowledge Infrastructure, Wanfang Database, Chongqing VIP, China Biology Medicine disc (CBMdisc), and references cited in related studies/reviews. Extracted data included the total effective rate, helicobacter pylori eradication rates, recurrence rate, and adverse reaction rate. Fifty-eight randomised controlled trials involving 5192 patients were included in the final analysis.

RESULTS

Results showed that Jianzhong decoction therapy was more effective than conventional Western medicine therapy (total effective rate, odds ratio [OR] = 4.29, 95% confidence interval [CI]: 3.51-5.23, P = 0.000; helicobacter pylori eradication rates, OR =2.10, 95% CI: 1.69-2.61, P = 0.000; recurrence rate, OR =0.23, 95% CI: 0.18-0.29, P = 0.000; and adverse reaction rate, OR =0.20, 95% CI: 0.12-0.33, P = 0.000).

CONCLUSIONS

Jianzhong decoction increased the total effective rate and helicobacter pylori eradication rate, and lowered the recurrence and adverse reaction rates. The results of this study can be used as a guide for clinical treatment of peptic ulcers.
