Sodium-Glucose Cotransporter-2 Inhibitor (SGLT2) in Major Depressive Disorder (MDD)

Summary

The primary purpose of this study is to determine whether empagliflozin, a medication in a class known as sodium-glucose cotransporter-2 inhibitors (SGLT2) inhibitors, may reduce symptoms of depression. Since this medication helps the body make metabolites known as ketone bodies which can serve as an alternate energy source for the brain, the investigators can also test whether ketone bodies help with depressed mood.
