Nifuroxazide is a derivative of nitrofuran, has an antibacterial effect against gastrointestinal gram-positive bacteria from the genus Staphylococcus and some gram-negative bacteria from the family Enterobacteriaceae of the genus: Yersinia spp., Escherichia spp., Citobacter spp., Enterobacter spp., Salmonella spp.
Nifuroxazide does not have an antibacterial effect on bacteria of the species
Proteus vulgaris, Klebsiella spp., Proteus mirabilis and Pseudomonas aeruginosa.
He affects the composition of the normal bacterial flora of the digestive tract.
The detailed mechanism of action of the drug is unknown.
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 was there a cross-resistance 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. The drug is practically not absorbed from the digestive tract, it acts exclusively in the lumen of the intestine.
