鹽酸托莫西汀抑制劑Atomoxetine Hydrochloride?is the hydrochloride salt of?atomoxetine, a phenoxy-3-propylamine derivative and selective non-stimulant,?norepinephrine?reuptake inhibitor with cognitive-enhancing activity. Although its precise mechanism of action is unknown,?atomoxetine?appears to selectively inhibit the pre-synaptic?norepinephrine?transporter, resulting in inhibition of the presynaptic reabsorption of?norepinephrine?and prolongation of?norepinephrine?activity in the synaptic cleft. The effect on cognitive brain function may result in improved attention and decreased impulsivity and activity levels.
