A growing literature indicates that cognitive deficits represent a core symptom of nicotine withdrawal that predict relapse during smoking abstinence. However, the effects of cognitive-enhancing medications on nicotine taking and seeking are not clear. Here, we show that systemic administration of the acetylcholinesterase inhibitor donepezil, which improves cognitive performance in smokers, attenuated nicotine self-administration and the reinstatement of nicotine-seeking behavior in rats. These results suggest that donepezil may prevent smoking relapse in abstinent human smokers.
