A broad-spectrum antimicrobial agent, a derivative of 5-nitrofuran. It is assumed that the antimicrobial activity of nifuroxazide is caused by the presence in its composition NO2-group, which causes inhibition of dehydrogenase activity and disrupts the synthesis of proteins in pathogenic bacteria. Does not cause the emergence of drug-resistant strains, nor has cross-resistance been observed with other antibacterial drugs. The effectiveness of the action of nifuroxazide does not depend on the pH that exists in the lumen of the intestine, nor on the sensitivity of microorganisms to antibacterial drugs.
When used in therapeutic doses, it has bacteriostatic action, in high - bactericidal.
Highly active in relation to Campylobacter jejuni, Escherichia coli, Salmonella spp, Shigella spp; Clostridium perfringens, Vibrio cholerae, pathogenic Vibrions and Vibrio parahaemolytique, Staphylococcus spp.
Weakly sensitive to nifuroxazide: Citrobacter spp, Enterobacter cloacae and Proteus indologenes.
Resistant to nifuroxazide: Klebsiella spp, Proteus mirabilis, Providencia spp., Pseudomonas spp.
Nifuroxazide has no effect on saprophyte flora, does not disturb the balance of normal intestinal flora. With acute bacterial diarrhea, eubiosis of the intestine is restored. When infected with enterotrophic viruses prevents the development of bacterial superinfection.
