Application

Varenicline tartrate has been used to investigate its effect on sensorimotor gating in rats under prepulse inhibition (PPI). It is suitable for use as a reference standard in capillary isotachophoresis (ITP) coupled on-line with capillary zone electrophoresis (CZE) for the quantification of varenicline metabolite in urine samples. It is also suitable for use for testing its effect on locomotor and nonlocomotor behavioral deficits in rats.

Biochem/physiol Actions

Varenicline tartrate is a partial α4β2 nicotinic receptor agonist and α7 full agonist. Varenicline competitively binds to α4β2 receptors and partially stimulates without creating a full nicotine effect, while simultaneoudly blocking the ability of nicotine to bind to the receptors. Varenicline thus blocks the ability of nicotine to activate α4β2 receptors and stimulate the central nervous mesolimbic dopamine system, believed to be the neuronal mechanism underlying reinforcement and reward experienced upon smoking.

Varenicline (VAR), a smoking cessation aid that is a partial agonist at nicotinic receptors, mimics the reinforcement-enhancing effects of nicotine. Varenicline, when accompanied by non-drug cues, is self-administered by rats, though it is unclear whether this results from varenicline acting

An array of pharmacological and environmental factors influence the development and maintenance of tobacco addiction. The nature of these influences likely changes across the course of an extended smoking history, during which time drug seeking can become involuntary and uncontrolled.

Adolescence is a critical period in brain development that coincides with the initiation of alcohol use. Nicotinic acetylcholine receptors (nAChR) have been shown to modulate ethanol behaviors in adult humans and in animal models; however, the role of these receptors

Patients suffering from neuropsychiatric disorders such as substance use and addiction disorders show impaired decision-making, which may be associated with their psychiatric disorders. Previously, using a gambling test for rodents, we demonstrated that methamphetamine-dependent rats showed alterations in their decision-making
