Product Description

CAS no 443-48-1 Metronidazole 

Metronidazole on the body tissue and intestinal amoeba disease effect is significant, but also the human treatment of insect disease, the preferred drug, the mechanism is through the inhibition of amoeba protozoa redox reaction, so that the protozoa nitrogen chain break effect. In vitro experiments show that the drug concentration of 1 ~ 2mg / L, the dissolved tissue amoeba in 6 to 20 hours can occur morphological changes, all killed within 24 hours, the concentration of 0.2mg / L, 72 hours can be Kill the dissolved tissue amoeba, has been widely used in the treatment of intestinal and parenteral amoebiasis (such as amoeba liver abscess, pleural amoebiasis, etc.).
