Combination drug for intravaginal use, containing metronidazole and miconazole.
Metronidazole - antimicrobial and antiprotozoal drug, a derivative of 5-nitroimidazole. The mechanism of action is the biochemical reduction of the 5-nitro group of metronidazole by intracellular transport proteins of anaerobic microorganisms and protozoa. The restored 5-nitro group of metronidazole interacts with the DNA of a cell of microorganisms, inhibiting the synthesis of their nucleic acids, which leads to the death of bacteria and protozoa.
Active with respect to Trichomonas vaginalis, Gardnerella vaginalis, Giardia intestinalis, Entamoeba histolytica, as well as obligate anaerobes Bacteroides spp. (incl. Bacteroides fragilis, Bacteroides distasonis, Bacteroides ovatus, Bacteroides thetaiotaomicron, Bacteroides vulgatus), Fusobacterium spp., Veillonella spp., Prevotella (Prevotella bivia, Prevotella buccae, Prevotella disiens) and some gram-positive microorganisms (Eubacter spp., Clostridium spp., Peptococcus spp., Peptostreptococcus spp.). MPK for these strains is 0.125-6.25 μg / ml.
Metronidazole is insensitive to aerobic microorganisms and facultative anaerobes, but in the presence of mixed flora (aerobes and anaerobes) metronidazole acts synergistically with antibiotics effective against aerobes.
Miconazole - an effective antimycotic agent that exerts its effect, primarily on dermatophytes and yeast fungi. When intravaginal application is active mainly in relation to Candida albicans.
Miconazole inhibits the biosynthesis of ergosterol in fungi and changes the composition of other lipid components in the membrane, which leads to the death of fungal cells. Miconazole does not change the composition of normal microflora and pH of the vagina.
