This study aimed to evaluate the therapeutic benefits of pentoxifylline (PTX) in treatment of adult patients with MDD as it has anti-inflammatory and phosphodiastrase inhibition activities.
In this study, the investigators evaluated the potential antidepressant effect of PTX in adult patients with MDD. the investigators hypothesized that MDD patients taking add-on PTX would present greater amelioration of their depressive symptoms than patients taking add-on placebo. Furthermore, the investigators assessed the relationship between HAM-D score and several peripheral biomarkers as well as their role in diagnosis and therapeutic targets of MDD.
