How does Champix (Varenicline) work? When cigarette smoke is inhaled, the nicotine attaches itself to nicotine receptors in the brain, which release a chemical called dopamine. Dopamine is a naturally occurring chemical, which is associated with feelings of pleasure. Champix (Varenicline) works by attaching itself to the nicotine receptors and thereby preventing nicotine itself from binding to them. In addition, the bond between varenicline and the nicotine receptors causes a much lower amount of dopamine to be released than when nicotine attaches itself. By using this medication, the ordinary pleasure feelings associated with smoking a cigarette disappear, making it less likely for you to smoke.
