Pharmacological action of Metronidazole.

The nitro of metronidazole is reduced to cytotoxic active products by anaerobic bacteria in an anaerobic environment, which inhibits the DNA synthesis of sensitive bacteria, causes the death of bacteria and shows anti-anaerobic effect. It has a strong antibacterial effect on most anaerobic bacteria, but is ineffective against aerobic bacteria and facultative anaerobic bacteria. It is mainly used for the prevention and treatment of anaerobic bacteria caused by infection, such as respiratory tract, digestive tract, abdominal cavity and basin pus infection, skin soft tissue, bone and bone joint infection and endocarditis, septicemia and meningitis caused by Bacteroides fragile, in addition, it is also widely used in the prevention and treatment of oral anaerobic bacteria infection.

Product Method of Bulk Metronidazole Powder.

It is prepared by the addition of 2-methyl-5-nitroimidazole (see 25010) to ethylene oxide. Dissolve 2-methyl-5-nitroimidazole in formic acid, add ethylene oxide successively at 30-40 ° C, and add sulfuric acid in the middle of the feed. Gabi, reaction 1h. Recover formic acid under reduced pressure, dissolve with water, cool to 10℃, and filter. The filtrate was adjusted to pH=10 with sodium hydroxide solution, then placed for cooling, filtration, and water washing to near-medium reconstruction. Recrystallize with water. The activated carbon is decolorized, and metronidazole is obtained.
