Abstract: The present invention provides a method of treating depression disease in a treatment resistant patient comprising administering to a mucosal membrane of a patient an effective amount of a pharmaceutically acceptable composition comprising an effective amount of ketamine or dextromethorphan, wherein the mucosal administration of the ketamine or dextromethorphan containing composition allows for the mucosal absorption of the composition eliminating the digestive tract of the patient for effecting a rapid acting antidepressant treatment of the treatment resistant patient. This method includes administering the composition to a patient's mucosal membrane of a respiratory tract, a genitourinary tract, an oral tract, or rectal tract of the patient. A pharmaceutically acceptable composition comprising ketamine or dextromethorphan and a vehicle is disclosed. A biomarker for identifying a depressive disease is set forth.

Abstract: The present invention provides a method of treating depression disease in a patient comprising administering to a mucosal membrane of a patient an effective amount of a pharmaceutically acceptable composition comprising an effective amount of ketamine or dextromethorphan, or both ketamine and dextromethorphan, wherein the mucosal administration of the ketamine or dextromethorphan containing composition allows for the mucosal absorption of the composition eliminating the digestive tract of the patient for effecting a rapid acting antidepressant treatment of the patient. Preferably, this method includes administering the composition to the oral cavity, and more preferably to the buccal cavity, of the patient. A pharmaceutically acceptable composition comprising ketamine or dextromethorphan and a vehicle is disclosed. A biomarker for identifying a depressive disease is set forth. A method of treating depressive illness in a patient using dextromethorphan via the oral route is provided.
