Official title
Efficacy and Safety of Venlafaxine in the Treatment of Non-specific Low Back Pain
Overview
Chronic non-specific low back pain is the leading cause of productivity loss and disability worldwide, constituting a major public health challenge. This study aims to systematically evaluate and compare the role of the antidepressant drug Venlafaxine in chronic non-specific low back pain, which is of critical importance for optimising clinical practice and developing precise, individualised treatment regimens.
Interventions
- Drug Control Group
Participants in the control group will receive routine clinical care for chronic nonspecific low back pain. - Drug Venlafaxine group
Venlafaxine is administered orally at a starting dose of 75 mg once daily. In patients with insufficient pain response who can tolerate the adverse effects, the dose may be carefully titrated up to 225 mg once daily. The maintenance period is 3 months.
Primary outcome measures
- Change From Baseline in Average Low Back Pain Intensity at Month 3 [Time frame: 3 months after randomization]
Secondary outcome measures (9)
- Change From Baseline in Average Low Back Pain Intensity [Time frame: Baseline, 1 month, and 6 months after randomization]
- Change From Baseline in Functional Disability Assessed by the Roland-Morris Disability Questionnaire [Time frame: Baseline, 1 month, 3 months, and 6 months after randomization]
- Global Perceived Recovery [Time frame: 1 month, 3 months, and 6 months after randomization]
- Change From Baseline in Health-related Quality of Life Assessed by EQ-5D-5L [Time frame: Baseline, 1 month, 3 months, and 6 months after randomization]
- Change From Baseline in Sleep Quality Assessed by the Insomnia Severity Index [Time frame: Baseline, 1 month, 3 months, and 6 months after randomization]
- Change From Baseline in Back Pain Beliefs Assessed by the Back Beliefs Questionnaire [Time frame: Baseline, 1 month, 3 months, and 6 months after randomization]
- Change From Baseline in Neuropathic Pain Features Assessed by the painDETECT Questionnaire [Time frame: Baseline, 1 month, 3 months, and 6 months after randomization]
- Use of Nonsteroidal Anti-inflammatory Drugs [Time frame: Baseline, 1 month, 3 months, and 6 months after randomization]
- Incidence of Adverse Events [Time frame: From randomization to 6 months after randomization]
