Objective: The high incidence of Tension-type headache (TTH) has led to significant social and economic challenges. Given the widespread use of Chinese patent medicines (CPM) for TTH patients, this study aim to evaluate the efficacy of different CPMs in treating TTH by network meta-analysis. Methods: Eight databases were conducted to identify CPMs-related randomized controlled trials (RCTs) from database inception date to August 2023. The primary outcome was clinical efficiency rate. The secondary outcomes were numerical rating scale (NRS), frequency of headache, duration of headache, hamilton anxiety scale (HAMA), hamilton depression Scale (HAMD) and adverse reactions. ROB 2.0 were used for quality evaluation. Stata 15.1 and R 3.5.3 software were used for Bayesian network meta-analysis. Results: A total of forty-one RCTs were included, involving 3,996 patients and 8 CPMs. The network meta-analysis revealed that Shugan Jieyu capsule plus western medicine (WM) was the best choice of CPM for improving clinical efficiency rate [vs. WM: relative risk (RR) = 7.31, 95 % confidence interval (CI): (1.65, 56.71)]. Yangxue Qingnao granule plus WM was superior to other therapeutic combinations in reducing duration of headache [vs. WM: MD = 1.05, 95%CI(0.74, 1.40)]. Jieyu pill plus WM might have best effect in reducing HAMD [vs. WM: MD = 7.15, 95%CI(-3.77, 18.14)], HAMA scores [vs. WM: MD = −7.41, 95%CI(-13.39, −1.42)], and NRS scores [vs. WM: mean difference (MD) = 2.01, 95%CI(1.47, 2.55)]. In terms of the frequency of headache, although Yangxue Qingnao granule plus WM and Toutong-ning capsule plus WM performed best, the optimal CPMs in reducing the frequency of headache remain to be further explored. Furthermore, due to the limited safety evidence available, reliable safety conclusions could not be drawn. Conclusion: CPM can effectively improve headache symptoms, clinical efficiency, and quality of life in patients with TTH. However, research with high quality and large sample sizes is needed for further investigation due to the limitations of this study. |
