Mechanism Of Action
Nitrofurantoin is an antibiotic It is usually used in treating urinary tract infection. It is often used against E. coli. Bacteria reduce nitrofurantoin more rapidly than do mammalian cells, andthis is thought to account for the selective antimicrobial activity of the compound. Bacteria that are susceptible to the drug rarely become resistant during therapy. Nitrofurantoin is active against many strains of E.Coli and enterococci. However most species of Proteus and Pseudomonas and many species of Enterobacter and Klebsiella are resistant.

Nitrofurantoin is bateriostatic for most susceptible microorganism at concentration of = 32 g/mL or less(MIC) and is bacteriocidal at concentration of = 100 g/mL. The antibacterial activity is higher in an acidic urine.

The drug works by damaging bacterial DNA,since its reduced form is highly reactive. This is made possible by the rapid reduction of nitrofurantoin inside the bacterial cell by flavoproteins ( nitrofuran reductase) to multiple reactive intermediates that attack ribosomal proteins, DNA,respiration, pyruvate metabolism and other macromolecules within the cell.
