![]() These effects are reversed by GABAB antagonists demonstrating specificity. It is theorized that GABA-ergic agents reduce dopamine availability in the ventral striatum, thereby preventing the self-administration of psychoactive drugs. Further support for the role of dopamine is provided by Franklin and colleagues wherein both brain and behavioral responses to smoking cues were modulated by genetic variance in the dopamine transporter a key component regulating the dopamine system. Boileau and colleagues showed that three administrations of amphetamine within the same environment produced conditioned dopamine release in the ventral striatum accompanied by amphetamine-like behavioral responses. At least two studies reported that cocaine cues elicit craving and increased dopamine release in the striatum of cocaine addicted individuals. Similar findings are now being replicated in humans. īased on consistent preclinical studies over the last 30 years it is believed that the dopamine surge in the ventral striatum in response to addictive drugs and stimuli (cues) previously and repeatedly ‘paired’ with the drug leads to drug-motivated behaviors. However, quitting is not easily accomplished - 70% of smokers want to quit each year but less than 7% succeed. Quitting greatly reduces the risk of premature death related to lung and other types of cancer, coronary heart disease, stroke and numerous other illnesses (The Health Benefits of Smoking Cessation. The list of debilitating and/or fatal diseases that are worsened by or attributed to cigarette smoking continues to grow (Foundation for smoke-free America ). Keywords: Baclofen ® Addiction Tobacco Alcoholism Synthesis analogsĬigarette dependence is the most common form of chemical dependence in the nation and is as addictive as heroin, cocaine, or alcohol. We conclude by an open question to doctors (addictologists and psychiatrists) hoping an answer as soon as possible. Finally, we come back to discuss some problems related to properties of baclofen ® that needs to be resolved, and our current investigation, to improve the therapeutic activity of baclofen ®. The section on “Chemistry” describes the chemical components of cigarette smoke and addresses aspects of product design. Second part, summarizes the state of knowledge about the chemistry and toxicology of cigarette smoke. First, we present a brief overview of treatments of addictions for various substances of abuse, including alcohol, nicotine, and cocaine. This article provides a review of the use of baclofen ® in the treatment for different addiction. ![]() The ability of the GABA B agonist, baclofen ® to ameliorate nicotine and drug motivated behaviour, particularly with respect to its possible utility as a smoking cessation agent. GABA B agonists exert their effects indirectly, by quieting dopaminergic afferents. ![]() The surge in dopamine in ventral striatal regions in response to drugs of abuse and drug- associated stimuli is a final common pathway of addiction processes.
