Is Venlafaxine More Effective than Escitalopram and Nortriptyline in the Management of Painful Symptoms in Patients with Major Depression?

BACKGROUND: Conflicting data regarding the efficacy of antidepressants of different mechanism of action on unexplained painful physical symptoms (UPPS) in depression have been published so far.

OBJECTIVE: The aim of this study was to compare the impact of escitalopram (ESC), nortriptyline (NOR), and venlafaxine (VEN) on UPPS in patients with major depression.

MATERIALS AND METHODS: Sixty patients, participants in the GENDEP study, with a diagnosis of depression according to the ICD-10 criteria were randomly assigned to treatment with ESC (10-30 mg, mean dose 15.2, standard deviation [SD]±9.2) or NOR (50-150 mg, mean dose 106.2, SD±8.2). Additionally, 30 patients who were treated with VEN (75-225 mg, mean dose 181.3, SD±8.8) were included. Before inclusion (day 0) and throughout the study (days 14, 28, 42, 56), the severity of pain was monitored using the visual analog scale.

RESULTS: The patients treated with ESC, NOR, and VEN did not differ in the intensity of pain at days 0, 14, 28, 42, and 56.

CONCLUSION: Our results do not support the hypothesis suggesting the superiority of VEN over ESC and NOR in the management of UPPS in major depression.
