Nicotinell TTS 30mg patches belong to the class of medications known as nicotine replacement therapies. These patches work by delivering a controlled amount of nicotine through the skin into the bloodstream, helping to reduce withdrawal symptoms and cravings associated with quitting smoking. Nicotine replacement therapy aims to ease the process of smoking cessation by providing a less harmful alternative to smoking. By gradually reducing nicotine dependence, Nicotinell TTS patches support individuals in breaking the habit of smoking.
