Pharmacological properties
Pharmacodynamics. As a bactericidal and fungistatic agent, dequalinium chloride acts on microorganisms that cause mixed infections of the oral cavity and throat. The spectrum of action of this local chemotherapeutic agent is very wide and includes most gram-positive and gram-negative bacteria, as well as fungi, spirochetes and pathogenic microorganisms that cause mixed infections of the oral cavity and throat. The accumulation of dibucaine hydrochloride in the body relieves the pain symptom that accompanies infections of the oral cavity and throat.
Microorganisms resistant to dequalinium chloride are unknown.
Does not cause caries.
Pharmacokinetics. The main active ingredient is absorbed in very small quantities.
Indication

Decatylen can be used in cases of mixed infection of the oral cavity and throat (on the recommendation of a doctor); as an adjuvant in the treatment of catarrhal, lacunar angina and Plaut-Vincent angina; in case of candidiasis of the oral cavity and pharynx.
