Metronidazole Usage And Synthesis
Brand Name(s)Flagyl and generic
Indications and UsageMetronidazole is a nitroimidazole antibiotic, also known as metronidazol and novonidazol. It was initially used to treat vaginal trichomaniasis, with very significant clinical effects. It is broadly used to prevent and treat oral anaerobic infections. In hospitals, it has been used frequently to prevent and treat respiratory, gastrointestinal, peritoneal, pelvic, skin, soft tissue, joint, and brain infections, cardiomyitis, and septicemia caused by anaerobic bacteria. The effectiveness of Metronidazole towards treating body tissue and intestinal amoebiasis is significant, and it the preferred drug to treat parasitosis.
Mechanisms of ActionMetronidazole kills anaerobic microorganisms, and its metabolites in the body during reduction also inhibit them by inhibiting DNA synthesis, thus interfering with bacterial growth and propagation, eventually killing them. Anaerobic bacteria affected include: Bacteroides fragilis, Fusobacterium (so named because of its sharp fusiform shape at both ends,) Clostridium tetani, Peptostreptococcus, and Giardia lamblia. Its mechanism of action in the treatment of parasites is to disrupt protozoans’ nitrogen chains by inhibiting their redox reactions. In vitro experiments have shown that at concentrations of 1-2 mg/L, morphological changes occurred in dissolved amoeba starting at 6-20 hours, killing them all within 24 hours. At a concentration of 0.2 mg/L, dissolved bacteria were killed within 72 hours.
Warnings and PrecautionsInteractions with nitroimidazole antibiotics, ethanol, and nicotine interfere with the oxidation of ethanol and can cause disulfiram reactions, causing symptoms like faster heart rate and decreased blood pressure, so patients should avoid contact with alcohol and smoke less during treatment in order to prevent the occurrence of adverse reactions.
Methods of productionIt is synthetized by 2-methyl-5-nitro imidazole (see 25010) and ethylene oxide addition. 2-methyl-5-nitro imidazole dissolved in formic acid and at 30-40℃ successive adding epoxy ethane, and sulfuric acid in the middle of adding feeding. and reaction for 1 h, after that. Decompression to recycle formic acid, water solution is cooled to 10 ℃, filter. The filtrate with sodium hydroxide solution to adjust pH = 10. Set aside to cool, filtering, washing to nearly alterations into neutral, recrystallization in water. Activated carbon decolorization to get metronidazole.
Chemical Propertieswhite to slightly yellow crystalline powder
UsesUsed as an antibacterial in the treatment of rosacea. Antiprotozoal (trichomonas). A potential human carcinogen.
DefinitionChEBI: A member of the class of imidazoles substituted at C-1, -2 and -5 with 2-hydroxyethyl, nitro and methyl groups respectively. It has activity against anaerobic bacteria and protozoa, and has a radiosensitising effect on hypoxic tumour cells. It may be given by mouth in tablets, or as the benzoate in an oral suspension. The hydrochloride salt can be used in intravenous infusions. Metronidazole is a prodrug and is selective for anaerobic bacteria due to their ability to intracellularly reduce the nitro group of metronidazole to give nitroso-containing intermediates. These can covalently bind to DNA, disrupting its helical structure, inducing DNA strand breaks and inhibiting bacterial nucleic acid synthesis, ultimately resulting in bacterial cell death.
General DescriptionWhite to pale-yellow crystalline powder with a slight odor. Bitter and saline taste. pH (saturated aqueous solution) about 6.5.
Air & Water ReactionsInsoluble in water.
Reactivity ProfileMetronidazole darkens on exposure to light. Metronidazole is incompatible with strong oxidizing agents. .
Fire HazardFlash point data for Metronidazole are not available; however, Metronidazole is probably combustible.
Contact allergensMetronidazole is a nitro-6-imidazole compound with antiprotozoal and antibacterial properties. Topical exposure may induce allergic contact dermatitis. Sensitization is mainly observed with the treatment of rosacea and rarely occurs from handling of table??????????????????????????????????????????????????????????
