Brief summary
Given 1) the established safety with short-term or long-term supplementation of Cr, 2) its potential usefulness in improving brain energy metabolism, 3) the reported abnormality in brain energy metabolism in MDD subjects, and 4) plausible association between depression and inflammatory mediators, we hypothesize that oral Cr augmentation will help reduce symptoms in MDD patients as well as normalize a deficit in brain energy metabolism and that improvement of MDD and brain energy metabolism will be correlated with inflammatory mediators changes. In this study, we plan to conduct an randomized, double-blind, placebo-controlled augmentation study with creatine in addition to escitalopram. We will assess the efficacy and safety of the Cr augmentation and evaluate changes relevant to brain energy metabolism and inflammatory mediators.
Interventions
In addition to 10-20mg escitalopram, the subjects will be given total 3 gram of creatine (500mg/capsule) a day in first week and then, 5 gram a day in the rest of the weeks.
In addition to 10-20mg escitalopram, the subjects will be given total 6 capsules of placebo (equal quantities to those of creatine group) a day in first week and then, 10 capsules a day in the rest of the weeks.
