Cetylpyridinium (used in a form of chloride salt) is a cationic surface-active agent and has a broad antimicrobial spectrum, with rapid killing of gram-positive pathogens and yeast in particular. It is suggested that interaction with bacteria occurs by the disruption of membrane function, leakage of cytoplasmic material, and ultimately the collapse of the intra-cellular equilibrium. The drug is used under various trade names as an oral OTC hygiene product (mouthwash, dental kits, etc.) to control the dental plaque and to prevent the subsequent gingivitis.

In Vitro Use Guide

The panel of 24 laboratory strains including 18 oral bacteria, five nonoral bacterialspecies and the yeast Candida albicans was incubated with twofold serial dilutions of the 0.05% cetylpyridinium chloride mouthrinse for 48-72 h at 35 celsius degrees. For the agar dilution assays of cultivable plaque bacte-ria, the drug was added at a final concentration of 1%. MIC values were 1.5-3% for Aggregatibacter actinomycetemcomitans and Capnocytophaga gingivalis, 0.375% for Actinomyces meyeri, Moraxella catarrhalis, Campylobacter rectus, 0.187-0.375 % for Porphyromonas gingivalis, etc.
