A New Quit Attempt

Varenicline Quit Line

Varenicline

Approved by FDA in May, 2006 Marketed as Chantix A non-nicotine medication A selective 42 Nicotinic

Acetylcholine Receptor Partial Agonist

Varenicline: A Highly Selective 42 Receptor Partial Agonist

Chantix

Chantix is an 42 nicotinic receptor partial agonist, a compound with dual agonist and antagonist activities. This is believed to result in both a lesser amount of dopamine release from the VTA at the nAcc as well as the prevention of nicotine binding at the 42 receptors

Nicotine

Binding of nicotine at the 42 nicotinic receptor in the Ventral Tegmental Area (VTA) is believed to cause release of dopamine at the Nucleus Accumbens (nAcc)
