Nifuroxazide - an intestinal antiseptic, a derivative of 5-nitrofuran, is highly active against Campylobacter jejuni, Escherichia coli, Salmonella spp., Shigella spp; Clostridium perfingens, 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 presumably inhibits the activity of dehydrogenases and the synthesis of proteins in bacterial cells. 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.Does not affect the composition of the normal bacterial flora of the digestive tract. With acute bacterial diarrhea, eubiosis of the intestine is restored. When infected with enterotrophic viruses prevents the development of bacterial superinfection.
