Nicotine Polacrilex USP/EP refers to a form of nicotine that is bound to a resin called polacrilex, meeting the standards outlined in the United States Pharmacopeia (USP) or the European Pharmacopoeia (EP). This formulation is commonly used in nicotine replacement therapies (NRTs) such as nicotine gum or lozenges. Nicotine polacrilex provides a controlled release of nicotine when chewed or dissolved in the mouth, helping individuals quit smoking by reducing withdrawal symptoms and cravings. The USP/EP designation ensures that the nicotine polacrilex meets strict quality and safety standards for pharmaceutical use. Users should follow the instructions provided by healthcare professionals or on the product label when using nicotine polacrilex products.
