Abstract: OBJECTIVE To observe the clinical effects of Bailemian Capsule combined with deanxit in treating patients with insomnia due to anxiety. METHODS 80 patients with insomnia due to anxiety were included and randomly divided into treatment group and control group， with 40 cases in each group. Patients in the treatment group were given Bailemian Capsule combined with deanxit， while whose in the control group were treated with deanxit only， with the treatment course lasting for 4 weeks. No other antianxiety agents， antipsychotics or sedative hypnotics were applied during the study. Patients who dropped out were eliminated from the analysis. Hamilton anxiety scale(HAMA)， sleep dysfunction rating scale(SDRS) and PSG parameters were applied to evaluate the curative effects. RESULTS Reducing scores on SDRS and HAMA of the treatment group before and after treatment were evidently higher than those of the control group(P<0.05). Both groups were effective in improving PSG parameters including sleeping time， sleep latency and sleep efficiency after treatment(P<0.05)， but the treatment group was superior to the control group(P<0.05). The total curative rate of treatment group and control group were 84.85% and 61.29% respectively， with a statistical significance between the two groups(P<0.05). CONCULSION Bailemian Capsule combined with deanxit is able to notably improve insomnia due to anxiety without increasing the side effects， which is batter than deanxit intake only， deserving further clinical application and promotion.
