Nicotinell TTS 10mg is a transdermal nicotine patch used in smoking cessation therapy. It belongs to the class of medications known as nicotine replacement therapies. Nicotine replacement therapy works by providing controlled amounts of nicotine to help reduce withdrawal symptoms and cravings associated with quitting smoking. Nicotinell TTS 10mg patches adhere to the skin, allowing nicotine to be absorbed slowly into the bloodstream. This gradual delivery helps manage nicotine withdrawal symptoms effectively.
