| abstract |
The present invention is directed to novel neuro-attentuating norketamine (NANKET) compounds according to any one of formulas (I—shown below), (I-A) and (I-B), or any of the compounds described in Tables A-D, or in any of the Examples provided herein, and pharmaceutically acceptable salts thereof, novel pharmaceutical formulations and novel methods of uses thereof. The present invention also features novel oral neuro-attenuating ketamine (NAKET) and neuro-attenuating norketamine (NANKET) modified-release pharmaceutical formulations, and novel methods of administration thereof, which ensure the steady release of a therapeutically effective amount of ketamine, norketamine, or derivatives thereof from the oral modified-release pharmaceutical formulations without neurologically toxic spikes in plasma concentration of the ketamine, norketamine, or derivatives during the release periods. |
