Champix - Smoking Cessation
Champix drug designed to help smokers quit without the use of
nicotine. Champix has accepted after clinical trials showed that
nearly half of smokers given the drug were able to stop their
habit. Unlike nicotine replacement therapies such as patches,
which release nicotine into the blood, Champix, whose generic
name is varenicline tartrate, provides free from withdrawal
symptons by sending a neurological signal to nicotine receptors
in the brain. By motivating these receptors, smokers are
provided with relief from their cravings. However, the drug also
partly blocks the same receptors, ensuring that if a patient
relapses they won’t receive the same level of pleasure from
smoking a cigarette.
