lidocaine + cetylpyridinium chloride

Lidocaine + cetylpyridinium chloride is a combination drug used primarily for the symptomatic relief of pain and minor infections in the mouth and throat. Lidocaine is an amide-type local anesthetic that works by reversibly blocking voltage-sensitive sodium channels in nerve cell membranes, thereby inhibiting pain signal transmission. Cetylpyridinium chloride is a quaternary ammonium antiseptic with broad-spectrum antimicrobial activity, particularly against gram-positive bacteria and to a lesser extent gram-negative bacteria. This combination is commonly formulated as lozenges, gels, or liquids for topical oral use to treat sore throat and minor oral infections[1][3][5].
