Translating the smoking cessation properties of the antidepressant nortriptyline using reinforcing, discriminative and aversive stimulus effects of nicotine in rats.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
rationaleThe antidepressant nortriptyline is a second-line pharmacotherapy for smoking cessation. Given that there is limited preclinical data available on the effects of nortriptyline on responses to nicotine, the present study sought to evaluate its effects on the reinforcing, discriminative stimulus (DS) and aversive effects of nicotine in male hooded Lister rats.
methodsThe effects of nortriptyline (0, 1, 3 and 10 mg/kg, i.p.) on responding under the control of a second order schedule of nicotine (0.03 mg/kg per infusion) intravenous self-administration (IVSA; n = 7), food-maintained responding (n = 6), discrimination of nicotine (0.2 mg/kg, s.c.) from saline in a two-lever procedure controlled by a fixed ratio and variable interval schedule of food reinforcement (n = 12) and on the development of nicotine- and lithium-induced conditioned taste aversions (CTA) (n = 8 per dose of nortriptyline) were examined.
resultsNortriptyline (3 mg/kg) reduced responding for nicotine in the drug-free interval in which behaviour was supported by nicotine-associated cues and subsequent intervals in which nicotine was available; however, food-maintained responding was also reduced at the same dose. Nortriptyline (3 mg/kg) blocked the development of a nicotine-induced CTA but not a lithium-induced CTA, indicating that these effects are unlikely to be due to non-specific effects of nortriptyline on taste perception or learning. Lastly, nortriptyline had no effect on the DS properties of nicotine.
conclusionsNortriptyline appears to attenuate the reinforcing and aversive stimulus properties of nicotine, which may mediate its anti-smoking effects. However, the results should be interpreted with caution, as non-specific effects of nortriptyline may have contributed to these findings.
