Release form

Flagyl is made in the form of peroral tablets No. 20 and in the form of vaginal candles No. 10.

Pharmacological action

Anti-protozoan and antibacterial.

Pharmacodynamics and pharmacokinetics

Flagyl (Flagyl), with active ingredient metronidazole, is medical drug from group of nitro-5-imidazoles and possesses the action mechanism directed to biochemical recovery metronidazolny 5 nitrogroups by transport cellular proteins of anaerobic and elementary microorganisms. The recovered metronidazolny 5 nitrogroup, interacting with cellular DNA of a microorganism, synthesis of nucleic acids oppresses, leading to a lysis of the most bacterial cell. The key product of a metabolism of metronidazole – 2 oxymetronidazole is also characterized by antimicrobic and antiprotozoan efficiency.

Antimicrobic and antiprotozoan activity of metronidazole is shown concerning many pathogenic microorganisms, including: dysenteric amoeba, trichomonads, intestinal lyambliya, peptokokk, clostridiums, fuzobakteriya, peptostreptokokk, and also obligate spore-forming and asporous anaerobic strains of bacteroids and some strains of eubakteriya.

Aerobic and optional anaerobic bacterial strains are insensitive to metronidazole.

Orally accepted metronidazole is quickly and almost in full soaked up in a gastrointestinal tract (approximately for 80% in 60 minutes). In parallel the eaten food does not influence absorption of drug. Bioavailability is equal actually 100%. At intake of 500 mg of metronidazole, its plasma concentration observed in an hour is at the level of 10 mkg/ml, and in 3 hours at the level of 13,5 mkg/ml.

T1/2 borrows from 8 to 10 hours. Linkng with serum proteins does not exceed 10-20% of the accepted dose. Metronidazole is characterized by fast penetration into organism fabrics/liquids (including skin, kidneys, lungs, a liver, saliva, bile, a vaginal secret, seed and cerebrospinal fluid), breast milk, and also passes through a placental barrier.

To metabolic transformations, by oxidation, hydroxylations and the glyukuronirovaniya, is exposed to about 30-60% of metronidazole. 2 oxymetronidazole (the main metabolite) also show anti-protozoan and antimicrobic activity.

40-70% of metronidazole are excreted by kidneys (for 35% in not changed form).

At renal pathologies repeated reception of metronidazole can lead to its serumal cumulation.

Vaginalno the administered drug in a dose of 500 mg (Flagyl of 500 mg) is systemically soaked up approximately for 20% therefore its plasma concentration makes about 12%, in comparison with the similar orally accepted single dose. Less than 20% of drug communicate plasma proteins. T1/2 at system use and normal hepatic function is equal to 8-10 hours.

Application instruction of Flagyl (Way and dosage)

Tablets Flagyl, application instruction

Flagyl in the form of tablets is intended for oral administration.

Treatment of an amebiasis at adults is carried out for 7 days in the daily dose of 1500 mg divided into 3 receptions.

Trichomoniasis at women (a vaginitis, an urethritis) and at men (urethritis) will respond to treatment in a single dosage of 2000 mg or course therapy for 10 days in the daily dose of 500 mg divided into 2 receptions.

Nonspecific vaginita treat for 7 days in the daily dose of 500 mg divided into 2 receptions.

Therapy of mephitic gangrenes assumes daily reception of 1000-1500 mg of drug.

The expressed disturbances of renal function (at KK less than 10 ml/min.) demand double decrease in daily dosages.

Candles Flagyl, application instruction

Flagyl in the form of candles is intended for vaginal use only by adult women. For the correct use of suppository it is necessary to release by means of scissors it from planimetric packaging and to enter into a vagina as it is possible more deeply.

Combined use of indirect anticoagulants leads to strengthening from effects and, as a result, to increase in a prothrombin time.

At the same time carried out therapy by Cyclosporine or drugs of lithium can become the reason of increase in their plasma contents.

Cimetidinum is capable to suppress metabolic transformations of metronidazole that can cause increase of its serumal concentration, than increase probability of emergence of side effects.

Parallel purpose of the remedies which are stimulators of microsomal liver enzymes (Phenytoinum, Phenobarbital) can increase metronidazole excretion that will lower its plasma concentration.

Metronidazole is capable to reduce clearance of a 5-ftoruratsil and to increase the serumal level of a busulfan that leads to increase of toxicity of these drugs.

Do not recommend to combine reception of metronidazole and not depolarizing muscle relaxants (a vekuroniya bromide).

At therapy of a female mecotic vaginitis and man's mecotic urethritis it is better to abstain from sexual contacts. Similar therapy of sexual partners, irrespective of existence at them visible symptoms of a disease is obligatory. During periods treatment should not be stopped. After carrying out therapy of trichomoniasis purpose of control tests throughout 3 subsequent cycles taken before and after periods is reasonable.
