Clinical trial
The Phosphodiesterase 4 Inhibitor Roflumilast as an Adjunct to Antidepressants in Major Depressive Disorder Patients. Proof-of-Concept, Randomized, Double-Blind, Placebo-Controlled Trial
Name
10/2021NEUR2
Description
n pre-clinical studies and early-stage clinical trials, PDE4 inhibitors such as rolipram have been shown to enhance memory. They also improve depressive-like behaviors induced by chronic unpredictable mild stress, lipopolysaccharide, or ethanol abstinence . Consequently, it is reasonable to believe that PDE4 is a potential target for treatment of the comorbidity of depression and AD.The aim of the current study is to evaluate the potential adjunct antidepressant effect of the Phosphodiesterase-4 Inhibitor Roflumilast in adult patients with MDD.
