Used as a psychotropic agent with both stimulant and antidepressant properties, primarily in the treatment of depression and anxiety disorders. It acts as an anticholinergic compound, modulating central nervous system activity to improve mood and cognitive function. Historically employed to enhance mental alertness and reduce fatigue in patients with mild to moderate depression. Also investigated for its potential to improve learning and memory, though its use has declined due to side effects related to anticholinergic activity.
