Metronidazole capsules

Metronidazole has a strong antibacterial effect on most anaerobic bacteria, but has no effect on aerobic bacteria and facultative anaerobes. The antibacterial spectrum includes Bacteroides fragilis and other Bacteroides, Fusobacterium, Clostridium perfringens, Eubacterium, Veillonella, Peptococcus and Peptostreptococcus. Its bactericidal concentration is slightly higher than the inhibitory concentration. In addition, it also has a strong killing effect on amoeba and Trichomonas. The bactericidal mechanism of metronidazole has not been fully elucidated. The nitroreductase of anaerobic bacteria plays an important role in the energy metabolism of sensitive strains. The nitro group of this product is reduced to a cytotoxin, which acts on the DNA metabolism process of bacteria and promotes cell death. The mechanism of anti-amoeba is to inhibit its redox reaction and break the nitrogen chain of the protozoa.
