This clinical trial is focused on studying Major Depressive Disorder, a condition characterized by persistent feelings of sadness and loss of interest. The study is exploring the effects of an anti-inflammatory medication called Celecoxib, which is typically used to relieve pain and inflammation. Participants in the study will receive either Celecoxib or a placebo to determine if Celecoxib is more effective in reducing symptoms of depression when added to their usual treatment, which may include medication or therapy.
The purpose of the study is to evaluate whether a 12-week treatment with Celecoxib, taken orally at a dose of 400 mg per day, can help reduce depressive symptoms more effectively than a placebo. The study will last for 12 weeks, during which participants will continue their regular treatment for depression. The study aims to see if Celecoxib can improve symptoms such as low energy and mood, which are common in people with depression.
Participants will be monitored throughout the study to assess changes in their symptoms and overall well-being. The study will also look at other factors like fatigue, sleep, anxiety, and any side effects experienced. By the end of the study, researchers hope to better understand the potential benefits of using Celecoxib as an additional treatment for people with Major Depressive Disorder.
