Nicotine Polacrilex, conforming to the standards of the United States Pharmacopeia (USP) or European Pharmacopoeia (EP), is a pharmaceutical-grade form of nicotine commonly used in nicotine replacement therapies (NRTs). It is available in various formulations such as chewing gum, lozenges, or patches designed to help individuals quit smoking by delivering controlled doses of nicotine to alleviate withdrawal symptoms. Nicotine polacrilex is designed to be slowly released and absorbed through the lining of the mouth, providing a safer alternative to smoking while helping individuals gradually reduce their dependence on nicotine. It is essential to use nicotine polacrilex as directed and under the guidance of healthcare professionals to maximize its effectiveness in smoking cessation efforts.
