Introduction: Tobacco dependence is a chronic disorder that carries the risk of relapse at any time point during abstinence. It is a major health issue in the world and current pharmacotherapies have had limited efficacy. Therefore, development and validation of novel treatments are required.
Objective: Investigate the novel neutral cannabinoid-1 receptor antagonist AM4113 on nicotine (main psychoactive ingredient in tobacco)-taking behaviour in animals.
Methods: Using the nicotine intravenous- and food control- self administration paradigms, we tested the acute and chronic (10-days) effects of AM4113 on nicotine- and food-taking behaviour.
Results: Acute AM4113 treatments (1-, 3-, 10-mg/kg) reduced nicotine self administration. Chronic AM4113 administration (10mg/kg) produced a sustained reduction of nicotine-taking behaviour during the course of the treatment. In the similar food control self administration experiments, AM4113 overall produced no effect.
Conclusion: AM4113 can attenuate nicotine-taking behaviour and its effect is sustained under chronic treatment.
