The researchers done a retrospective systematic review of 1850 members (930 in cure teams, 920 in control groups) from 19 randomized controlled trials evaluating Wuling capsule in older people with sleeplessness, from databases in MEDLINE, EMBASE, Ovid, Cochrane Library, Chinese National Awareness Infrastructure, VIP information and facts database, Chinese Biomedical Databases, and Wanfang, from 2008 to 2021. Wuling capsule was as opposed with benzodiazepines in 8 of the trials, and, Wuling capsule as well as benzodiazepines was in comparison with benzodiazepines in 4 trials. All trials lasted amongst 4 and 12 months.

PSQI scores ended up diminished with Wuling capsule (MD: -1.92, 95% CI, [-2.34 – -1.50] P <.00001 I2 = 95%) compared to control individuals, and Wuling capsule significantly outperformed the control groups as monotherapy (MD: -1.71, 95% CI, [-2.33 – -1.09] P <.00001 I2 =97%) and as adjunctive therapy (MD: -2.10, 95% CI, [-2.66 – -1.55] P <.00001 I2 = 90%).

Wuling capsule proved more effective for insomnia when used for 8 weeks than for 4 weeks (MD: -2.57, 95% CI, [-3.52 – -1.62] P <.00001 I2 = 93%) and (MD: -1.68, 95% CI, [-2.13 – -1.22] P <.00001 I2 = 95%), respectively. In comparison to benzodiazepines, Wuling capsule lowered SDRS scores (MD: -4.21, 95% CI, [-4.95 – -3.46] P <.00001 I2 = 0%). The drug significantly reduced adverse events compared to controls (RR: 0.47, 95% CI, [0.34 – 0.65] P <.00001 I2 = 43%).

The study had several limitations, the researchers acknowledged. Among the limitations, included the missing details of randomization in many of the studies to heterogeneity and publication bias.

“Wuling capsule can safely and effectively improve sleep quality in patients with insomnia disorder,” according to researchers. However, “the findings of this study are not strong enough to support the use of Wuling capsule as a treatment for insomnia disorder,” they concluded.
