Champix contains the medicine varenicline that is used to help people stop smoking. Varenicline reduces craving and helps deal with nicotine withdrawal symptoms. It also makes smoking less pleasurable which helps in quitting smoking.
Champix is used to help smokers quit effectively. It works by reducing cravings for nicotine and helps cope with withdrawal symptoms like an urge to smoke again and feeling depressed or irritable which smokers generally experience when they are trying to quit. Smokers who are using Champix will find that they find smoking less pleasurable, and it is easier to stop smoking. Champix is only available on prescription and comes in the form of tablets.
Champix has been proved to help smokers quit effectively in a laboratory setting. The same study also showed that patients who used Champix were able to remain non-smokers after treatment.
Smokers become addicted to nicotine, a chemical that is found in tobacco that cigarettes have. Nicotine binds with receptors in our nervous system and helps release dopamine, a neurotransmitter that is responsible for how people experience pleasure.
It is believed that Varenicline, the active ingredient in Champix activates these receptors and blocks nicotine from attaching to them. Champix does not contain nicotine and it is not addictive.
The average course of taking these tablets is 12 weeks and they come as 0.5mg and 1mg tablets.
