Pharmacodynamics. Metronidazole, active ingredient of Gravagin, is derivative 5 nitroimidazoles, possesses a wide range of antimicrobic action in relation to gram-positive and gram-negative anaerobic bacteria, and also protozoa.

The mechanism of effect of metronidazole is connected with disturbance of synthesis of nucleic acids in DNA of microorganisms that leads to their death. Besides, the nitrogroup of a molecule of metronidazole, being an acceptor of electrons, is built in a respiratory chain of protozoa and anaerobe bacterias (competes with elektrontransportiruyushchy proteins — flavoproteins) that breaks respiratory processes and causes death of microorganisms.

Pharmacokinetics. At intravaginalny use drug creates high antimicrobic and anti-protozoan concentration of metronidazole in a vagina, a neck of uterus, a cavity and walls of a uterus, bodies of a small pelvis. System absorption of metronidazole makes 10-15 %, other part is brought out of an organism with vulval allocations for days. The elimination half-life of the metronidazole which got to system blood circulation makes 8-10 hours. 10-20 % of metronidazole contact blood proteins. Gets into most bodies and liquids of an organism, including breast milk, a vaginal secret, through a placenta in the same concentration, as in a blood plasma. It is metabolized in a liver generally by oxidation and conjugation with glucuronic acid, 60-80 % are removed with urine, the rest — through intestines. Metabolites of metronidazole paint urine in red-brown color.

It is necessary to remember risk of deterioration in the neurologic status of patients with a serious chronic or acute neurologic illness at treatment by metronidazole. It is necessary to stop treatment at emergence of an ataxy, dizziness, hallucinations and at deterioration in the neurologic status of the patient. Metronidazole is capable to immobilize treponemas that can result in false positive results at test of Nelson. Patients have to be warned that during Gravagin's use it is necessary to refuse completely alcohol intake, and also the medicines containing alcohol. At use of vaginal suppository along with condoms or vaginal diaphragms the risk of a rupture of latex can increase.

Reported about cases of psychotic reactions at patients who accepted at the same time metronidazole and Disulfiramum. Gravagin exponentiates effect of indirect anticoagulants therefore in case of need combined use it is necessary to monitorirovat daily MHO (the international normalizing relation) and if necessary to reduce an anticoagulant dose. Lithium level in a blood plasma at simultaneous use with metronidazole can increase. It is necessary to control concentration of lithium, creatinine and electrolytes in a blood plasma at patients who accept lithium and metronidazole. At combined use with Phenytoinum or phenobarbital metronidazole level in a blood plasma can umenshatsya.
