Randomized Controlled Trial Multicenter Study Comparative StudyComparisons of the efficacy and tolerability of extended-release venlafaxine, mirtazapine, and paroxetine in treatment-resistant depression: a double-blind, randomized pilot study in a Chinese population.
To compare the efficacy and tolerability of antidepressants switch with extended-release venlafaxine (venlafaxine-XR), mirtazapine, and paroxetine in Chinese patients with major depressive disorder who had 2 consecutive unsuccessful antidepressant trials. One hundred fifty adult patients with treatment-resistant depression according to their medical records and/or response to current treatments were randomly assigned to receive fixed-dosage treatment of venlafaxine-XR 225 mg/d (n = 50), mirtazapine 45 mg/d (n = 55), or paroxetine 20 mg/d (n = 45) for 8 weeks. The primary outcome was the remission rates that were defined as a score 7 or lower on the 17-item Hamilton Rating Scale for Depression (HRSD-17). ⋯ Similarly, there were also no significant differences between groups in secondary outcome measure. Venlafaxine-XR, mirtazapine, and paroxetine were equally effective in the treatment of Chinese patients with major depressive disorder who failed at least 2 previous antidepressant treatments. Selecting any of these 3 antidepressants as a third-step antidepressant is a reasonable choice for this group of patients.
