Efficacy of Acupuncture Combined With Pharmacotherapy for Depression: A Randomized Controlled Clinical Trial

Background: Depression is frequently accompanied by comorbid symptoms such as anxiety, insomnia, and cognitive impairment, which complicate treatment and adversely affect clinical outcomes. Acupuncture has shown promise as a complementary therapy; however, the efficacy of acupuncture combined with selective serotonin reuptake inhibitors (SSRIs) requires further investigation. Methods: This single-center, randomized clinical trial enrolled 213 inpatients with depression and comorbid symptoms. Participants were randomly assigned to receive either SSRIs treatment or antidepressant treatment combined with acupuncture for two weeks. Clinical outcomes were assessed using the Hamilton Depression Rating Scale (HAMD), Hamilton Anxiety Rating Scale (HAMA), Mini-Mental State Examination (MMSE), Pittsburgh Sleep Quality Index (PSQI), and Beck Scale for Suicide Ideation (BSI). The primary outcome was the change in the HAMD reduction rate. Results: < 0.05). Hierarchical regression analyses indicated that baseline symptom severity and duration of illness were significant predictors of treatment response. Conclusions: When used as an adjunct to antidepressant therapy, acupuncture provides rapid and broad therapeutic benefits for patients with depression. Compared with SSRI monotherapy, the combined treatment was associated with greater improvements in depressive and anxiety symptoms, sleep quality, and cognitive performance. These findings support the integration of acupuncture into multimodal treatment strategies for managing the complex symptom profile of major depressive disorder.
