Coluracetam is a nootropic drug of the racetam family. Coluracetam was initially developed and tested by the Mitsubishi Tanabe Pharma Corporation for Alzheimer's disease. After the drug failed to reach endpoints in its clinical trials it was in-licensed by BrainCells Inc for investigations into major depression disorder (MDD), after being awarded a "Qualifying Therapeutic Discovery Program Grant" by the state of California.
