[Efficacy and safety of Kuntai capsule and estrogen for menopausal syndrome: a meta-analysis].

Objective: To evaluate the efficacy and safety of Kuntai Capsule and Estrogen for Menopausal Syndrome.

Methods: Related randomized controlled trials about Kuntai capsule and estrogen in recent 10 years were collected by various kinds of database according to strict inclusion and exclusion criteria. Valid data were extracted to conduct meta-analysis by RevMan5.0.

Results: A total of 196 articles were retrieved, but only 6 were finally included. Meta-analysis showed that no significant differences were observed in Kupperman score between Kuntai group and estrogen [WMD = 0.22, 95%CI (-1.14, 1.58), P > 0.05]. While E(2) level was significantly higher in estrogen group than that in Kuntai [WMD = -59.59, 95%CI(-87.35, -31.83), P < 0.01]. The incidence of adverse effects was significantly lower in Kuntai group compared to the estrogen group [RR = 0.61, 95%CI(0.45,0.83), P < 0.01].

Conclusion: Kuntai can improve symptoms of menopausal syndrome effectively as the same as estrogen and tends to have lower incidence of adverse effects.
