Efficacy and safety of toludesvenlafaxine hydrochloride sustained-release tablets in depression with ineffective or partially effective initial antidepressant treatment: a single-arm, multicenter clinical study.

Purpose: Depression is one of the leading causes of avoidable suffering worldwide, and over 50% of patients do not respond to their first antidepressant treatment, which underscores the need for more effective alternatives. This clinical predicament urgently requires an effective solution. The core objective of this study is to clarify the clinical efficacy and application value of the triple reuptake inhibitor toludesvenlafaxine in patients with poor response to the first antidepressant therapy, providing a new basis for treatment options for this refractory group. Methods: This multicenter study included 61 patients meeting Results: For such patients that did not respond to the first treatment, significant and rapid efficacy was demonstrated after switching to toludesvenlafaxine. At 8 weeks of treatment, the average MADRS score of the patients decreased by 15.5 points compared with the baseline (95% CI, -17.7 to -13.3; Conclusion: This study confirmed that toludesvenlafaxine not only has significant clinical efficacy (including early onset, high remission, and response) for patients with depression who did not respond to the first antidepressant treatment, but also has good safety and can improve sexual dysfunction that affects compliance. This result highlights the significant position of toludesvenlafaxine in addressing the key clinical challenge of first treatment failure, providing a highly valuable new option for the subsequent treatment of such patients.
