Varenicline Approved by FDA in May, 2006 Marketed as Chantix A non-nicotine medication A selective  4  2 Nicotinic Acetylcholine Receptor Partial Agonist

Varenicline: A Highly Selective  4  2 Receptor Partial Agonist Chantix Chantix is an  4  2 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  4  2 receptors Nicotine Binding of nicotine at the  4  2 nicotinic receptor in the Ventral Tegmental Area (VTA) is believed to cause release of dopamine at the Nucleus Accumbens (nAcc)
