A nicotine lozenge is a modified-release dosage tablet (usually flavored) that contains a dose of nicotine polacrilex, which dissolves slowly in the mouth to release nicotine over the course of 20 to 30 minutes. Nicotine lozenges are intended to help individuals quit smoking and are generally an over-the-counter medication. Nicotine lozenges are commonly found in 2 mg and 4 mg strengths, although other strengths may be found. The nicotine is absorbed through the lining of the mouth and enters the blood vessels. It is used as an aid in nicotine replacement therapy (NRT), a process for smoking cessation.
