Anatabine significantly decreases nicotine self-administration

Area of Science:

• Pharmacology
• Neuroscience
• Addiction Research

Background:

• Nicotine addiction causes lethal diseases, necessitating novel smoking cessation aids.
• Anatabine, a tobacco alkaloid, has unknown effects on nicotine's abuse potential.

Purpose of the Study:

• To investigate anatabine's effects on nicotine self-administration and abuse liability.
• To evaluate anatabine as a potential smoking cessation medication.

Main Methods:

• Rhesus monkeys self-administered nicotine and food under a second-order schedule.
• Anatabine or saline was administered prior to sessions, and its effects on responding were measured.
• The nicotine dose-effect curve was assessed with and without anatabine treatment.

Main Results:

• Anatabine dose-dependently reduced nicotine self-administration.
• High doses of anatabine decreased food-maintained responding, but not significantly at lower doses.
• Anatabine did not increase self-administration, indicating low abuse liability.

Conclusions:

• Anatabine effectively reduces nicotine self-administration in non-human primates.
• Anatabine shows promise as an agonist medication for treating nicotine addiction.
