Release form and composition
The dosage form of the drug is vaginal suppositories: torpedo-shaped, from white to yellowish-white (in a cardboard box, instructions for the use of Metrovagin and 2 blister packs of 5 suppositories each).

Pharmacological properties
Pharmacodynamics
Metronidazole is a 5-nitroimidazole derivative with antiprotozoal and antibacterial properties.
The mechanism of action of the drug consists in the biochemical reduction of the 5-nitro group of metronidazole by intracellular transport proteins of protozoa and anaerobic microorganisms. Subsequently, the reduced 5-nitro group of metronidazole, inhibiting the synthesis of nucleic acids, interacts with the DNA of the cells of pathogenic bacteria, due to which they die.
Metrovagin is active against the following microorganisms:
- microaerophiles: Helicobacter pillory, Gardnerella vaginalis;
- gram-negative anaerobes: Fusobacterium spp., Bacteroides spp. (including B. ovatus, B. distasonis, B. thetaiotaomicron, B. fragilis, B. vulgatus);
- gram-positive anaerobic cocci: Peptostreptococcus spp., Peptococcus niger;
- protozoa: Lamblia intestinalis, Entamoeba histolytica, Trichomonas vaginalis, Balantidium coli;
- gram-positive anaerobic spore-forming rods: Clostridium spp., Eubacterium spp.
The MIC (minimum inhibitory concentration) of these strains ranges from 0.125 to 6.25 μg / ml.
Pharmacokinetics
With intravaginal use of Metrovagin suppositories, approximately 56% of metronidazole undergoes systemic absorption.
The bioavailability of the drug is 20%. No more than 20% binds to plasma proteins.
Metronidazole penetrates into most body tissues, into breast milk, through the blood-brain barrier and the placenta.
The drug undergoes biotransformation in the body in three ways: glucuronidation, oxidation and hydroxylation. The main metabolite is 2-oxymetronidazole. Its activity is approximately 30% of that of metronidazole.
The half-life is 6-11 hours. From 40 to 70% is excreted through the kidneys, with about 20% unchanged.
Indications for use
Metrovagin is used to treat Trichomonas and nonspecific vaginitis in women.

- from the digestive system: dry mouth, metallic taste in the mouth, change in taste, cramping pain in the abdominal cavity, decreased appetite, diarrhea / constipation, nausea, vomiting;
- on the part of the hematopoietic organs: a decrease or increase in the number of leukocytes in the blood compared with the norm;
- from the central nervous system: headache, dizziness;
- others: in rare cases, urine staining red-brown, irritation or burning sensation of the partner's penis.
Overdose
In case of an overdose of the drug, ataxia may develop, the appearance of nausea and vomiting.

special instructions
The duration of drug treatment should not exceed 10 days. You cannot conduct more than 3 courses per year.
With the simultaneous administration of oral metronidazole, especially in the case of a repeated course of treatment, it is necessary to monitor the peripheral blood picture due to the risk of leukopenia.
During the treatment with Metrovagin of Trichomonas vaginitis, women should refrain from sexual intercourse. In addition, concomitant treatment of the sexual partner with a drug containing metronidazole (in oral dosage form) is recommended.
During treatment with the drug, one should refrain from drinking alcohol because of the risk of developing a disulfiram-like reaction, manifested by abdominal pain, nausea, vomiting, headache, and a sharp flush of blood to the face.

No information is available regarding recommendations for elderly patients.
Drug interactions
Barbiturates can reduce the effectiveness of Metrovagin, as they accelerate the inactivation of metronidazole in the liver.
Cimetidine inhibits the metabolism of the drug, which increases the concentration of metronidazole in the blood serum, increasing the risk of side effects.
The drug increases the concentration of lithium in the blood plasma. Enhances the effect of warfarin and other indirect anticoagulants, as a result of which an increase in prothrombin time is possible.
Metronidazole can be combined with antibiotics and sulfonamides.
Metrovagin is not recommended to be used simultaneously with non-depolarizing muscle relaxants (for example, vecuronium).
