Pharmacological properties.

Pharmacodynamics.

Stopangin is a disinfectant agent with moderate anesthetic action. The main active component, hexetidine, exhibits bactericidal and fungicidal effects. The antimicrobial action of hexetidine is achieved through competitive inhibition of thiamine pyrophosphate production, a coenzyme essential for microbial life processes. By acting on the glycolytic process, oxidation of food residues in the oral cavity is reduced. Hexetidine and, to some extent, essential oils contribute to the therapeutic effect of the product with a mild local anesthetic action.

Pharmacokinetics.

After application by the recommended route, absorption through the mucous membrane is negligible, although certain components contained in it (e.g., methyl salicylate) may be absorbed to a greater extent.

Clinical characteristics.

Indications.

− Disinfection of the oral cavity and pharynx in inflammatory and infectious diseases: tonsillitis, pharyngitis, gingivitis, periodontosis, stomatitis, glossitis, and aphthae;

− disinfection before and after tonsillectomy, tooth extraction, and other surgical interventions in the oral cavity;

− elimination of unpleasant oral odor;

− adjunctive medicinal agent in antibiotic treatment of streptococcal angina.
