Smoking cessation agents are medicines used to assist in quitting smoking. There are a few types of agents that can be used.
Nicotine replacement therapy (NRT) products deliver nicotine systemically and reduce the urge to smoke. These products are available as nicotine patches, gums, lozenges or inhalers.
Other smoking cessation agents work in the brain to either decrease the urge to smoke or to reduce cravings and withdrawal symptoms.
