Pharmacological action
Antiprotozoal, antibacterial.
Metronidazole belongs to nitro-5-imidazoles. The mechanism of action of metronidazole is the biochemical recovery of the 5-nitro group of metronidazole by intracellular transport proteins of anaerobic microorganisms and protozoa.
The reduced 5-nitro group of metronidazole interacts with the DNA of microorganism cells, inhibiting the synthesis of their nucleic acids, which leads to the death of microorganisms.
Metronidazole is an effective antimicrobial and antiprotozoal agent with a wide spectrum of action. The drug is highly active against Trichomonas vaginalis, Giardia intestinalis, Entamoeba histolytica, Lamblia intestinalis, as well as against obligate anaerobes (spore-and non-spore-forming) – Bacteroides spp. (B.fragilis, B.ovatus, B.distasonis, B.thetaiotaomicron, B.vulgatus), Fusobacterium spp., Clostridium spp., Peptostreptococcus spp., Peptococcus spp., Sensitive strains of Eubacterium.
Aerobic microorganisms and facultative anaerobes are not sensitive to metronidazole

Dosage and Administration
Inside. With amoebiasis, Flagil is used orally for 7 days at 1.5 g / day for 3 doses (adults).
Giardiasis is treated for 5 days: adults are prescribed 750-1000 mg / day, children 6-10 years old – 375 mg / day (1.5 tablets) and children 10-15 years old – 500 mg / day (2 tablets. ) For children under 6 years of age, the use of metronidazole in the form of a suspension is preferable.
With trichomoniasis in women (urethritis and vaginitis) Flagil is prescribed once in a dose of 2 g or as a course of treatment for 10 days: 1 tab. (250 mg) 2 times / day.
With trichomoniasis in men (urethritis), Flagil is prescribed once at a dose of 2 g or as a course of treatment for 10 days, 1 tab. (250 mg) 2 times / day.
For nonspecific vaginitis, 500 mg of Flagil is used 2 times / day for 7 days.
In the treatment of anaerobic infections, adults are prescribed Flagil at 1-1.5 g / day.
In case of severe renal impairment (CC less than 10 ml / min), it is recommended to reduce the daily dose by 2 times.
Side effects of
From the gastrointestinal tract: nausea, metallic taste in the mouth, dry mouth, decreased appetite, glossitis, stomatitis, pancreatitis, anorexia, epigastric pain, vomiting, diarrhea, constipation.

Drug Interaction
Similar to disulfiram causes ethanol intolerance.
Concomitant use with disulfiram can lead to the development of various neurological symptoms (at least 2 weeks between appointments).
Increases the effect of indirect anticoagulants, leading to an increase in the time of prothrombin formation.
When taken with lithium, the plasma concentration of the latter may increase.
When co-administered with cyclosporine, plasma concentrations of the latter may increase.
Cimetidine inhibits the metabolism of metronidazole, which may increase its serum concentration and increase the risk of side effects.
The simultaneous administration of drugs that stimulate enzymes of microsomal oxidation in the liver (phenobarbital, phenytoin) may accelerate the elimination of metronidazole, resulting in a decrease in its plasma concentration.
Metronidazole reduces the clearance of 5-fluorouracil, leading to an increase in its toxicity.
Metronidazole increases the level of busulfan in the blood plasma, leading to an increase in its toxicity (severe form).
It is not recommended to combine with non-depolarizing muscle relaxants (vecuronium bromide).
