Metronidazole tablets
Function and Efficacy
This product is a nitroimidazole derivative that can inhibit the redox reaction of amoeba and break the nitrogen chain of the protozoa. In vitro tests have shown that when the drug concentration is 1~2mg/L, the histolytica amoeba can undergo morphological changes in 6~20 hours and all are killed within 24 hours. When the concentration is 0.2mg/L, the histolytica amoeba can be killed within 72 hours. This product has a strong effect of killing trichomonas, and its mechanism is unknown. Metronidazole has a killing effect on anaerobic microorganisms, and the metabolites generated when it is reduced in the human body also have anti-anaerobic effects, inhibiting the synthesis of bacterial deoxyribonucleic acid, thereby interfering with the growth and reproduction of bacteria, and ultimately causing bacterial death. It has a carcinogenic effect on some animals.
