Nicotine Polacrilex USP/EP refers to a pharmaceutical-grade form of nicotine commonly used in nicotine replacement therapies (NRTs) such as nicotine gum and lozenges. This formulation meets the standards set by the United States Pharmacopeia (USP) and the European Pharmacopoeia (EP). Nicotine polacrilex is designed to provide a controlled release of nicotine when consumed orally, helping individuals reduce their dependence on smoking. It works by gradually delivering nicotine to the bloodstream, thereby alleviating withdrawal symptoms associated with smoking cessation.
