One of nicotine's effects on the body is at the level of the NMDA receptors in the brain. Memantine is a drug that also affects NMDA receptors, making it a candidate for the treatment of nicotine addiction. The purpose of this study is to evaluate the effectiveness of memantine using a laboratory model of tobacco addiction. We will compare the effects of memantine with bupropion, medication currently used to facilitate smoking cessation.

    Two capsules of Memantine twice daily for 12 days.
Detailed Description:

Tobacco use is the leading preventable cause of death in the United States. Recent research on the effects of nicotine on the brain and behavior presents an opportunity to advance medication development. Neurotransmission at NMDA receptors in the brain is associated with learning and memory and has been linked to many of nicotine's effects on humans. It is possible that altering NMDA neurotransmission may be helpful in treating nicotine addiction.

The goal of this study is to develop a laboratory model for early-stage testing of new and existing compounds for the treatment of tobacco and nicotine addiction. Specifically, the study will assess the effect of memantine, a non-competitive NMDA antagonist, versus bupropion, a medication currently used to facilitate smoking cessation, on various behavioral aspects related to smoking behavior, including reinforcement and cue-reactivity.

This double-blind, randomized assignment study will consist of three distinct phases (placebo, bupropion, and memantine). Each phase will include 10 days of outpatient medication maintenance, followed by 3 days of inpatient testing. During the outpatient phase, study visits will occur every 2 to 3 days. At these visits, compliance and side effects of medication will be monitored, smoking diaries will be collected, and medication will be dispensed. During the inpatient period participants will be allowed to smoke only at designated times. A variety of assessment will be conducted, including abstinence symptoms, acute effects of cigarettes, responses to cigarette cues, and cigarette self-administration.
