Composition of
In 1 ml of the drug in question, the active ingredients are:
- Neomycin sulfate( 5 mg) is a bactericidal antibiotic of the aminoglycoside group. Violates protein synthesis in microbial cells. Has an effect on most representatives of microflora, with the exception of P. Aeruginosa, the majority of streptococci, as well as fungi, anaerobic infections and viruses. Resistance to this antibiotic is manifested rather weakly and very slowly, which, undoubtedly, is a virtue in the fight against pathogenic microorganisms.
- Dexamethasone sodium phosphate( 1 mg) is a glucocorticosteroid that simultaneously possesses anti-allergic, anti-inflammatory and desensitizing properties. The combination of dexamethasone and an antibacterial agent in the drops of "Dexon" reduces the risk of developing the infectious process. Despite the advantages, there is a drawback: a small amount of dexamethasone enters the systemic circulation, which is a potential threat of various side effects.
- Excipients - preservative benzalkonium chloride, disodium hydrogen phosphate, sodium chloride, disodium EDTA, sodium metabisulphite, propylene glycol, creatinine, water for injection.
