Detailed Description:

Major depressive disorder (MDD) is a common, severe, chronic and often life-threatening illness. Major depression contributes to significant morbidity and mortality. Available pharmacotherapies for major depression are suboptimal in terms of speed of onset, efficacy, and tolerability. Current medications for severe, chronic mood disorders are not based on pathophysiological models of illness, but rather are variation of monoaminergic-based therapies. Org 24448 represents a new treatment approach for depression, by potentiating the AMPA receptor subfamily of ionotropic glutamate receptors. This drug has been shown to have antidepressant features in preclinical models, as well as cognitive-enhancing qualities.
