Single oral doses of Эдгил, up to 12g have been reported in suicide attempts and accidental overdoses. Symptoms were limited to vomiting, ataxia and slight disorientation. There is no specific antidote for Эдгил overdosage. In cases of suspected massive overdose, symptomatic and supportive treatment should be instituted.
Known hypersensitivity to nitroimidazoles, Эдгил or any of the excipients.
Not applicable.
The frequency of adverse events listed below is defined using the following convention:
Very common (>1/10); common (>1/100 to < 1/10); uncommon (>1/1,000 to < 1/100); rare (>1/10,000 to < 1/1,000); very rare (< 1/10,000), not known (cannot be estimated from the available data).
Serious adverse reactions occur rarely with standard recommended regimens. Clinicians who contemplate continuous therapy for the relief of chronic conditions, for periods longer than those recommended, are advised to consider the possible therapeutic benefit against the risk of peripheral neuropathy.

Reporting of suspected adverse reactions:
Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme at: www.mhra.gov.uk/yellowcard.
Эдгил has been shown to be carcinogenic in the mouse and in the rat following chronic oral administration however similar studies in the hamster have given negative results. Epidemiological studies have provided no clear evidence of an increased carcinogenic risk in humans.
Эдгил has been shown to be mutagenic in bacteria in vitro. In studies conducted in mammalian cells in vitro as well as in rodent or humans in vivo, there was inadequate evidence of a mutagenic effect of Эдгил, with some studies reporting mutagenic effects, while other studies were negative.
Эдгил is indicated in the prophylaxis and treatment of infections in which anaerobic bacteria have been identified or are suspected to be the cause.
Эдгил is active against a wide range of pathogenic micro-organisms notably species of Bacteroides, Fusobacteria, Clostridia, Eubacteria, anaerobic cocci and Gardnerella vaginalis.
It is also active against Trichomonas, Entamoeba histolytica, Giardia lamblia and Balantidium coli.
Эдгил is indicated in adults and children for the following indications:
1. The prevention of post-operative infections due to anaerobic bacteria, particularly species of Bacteroides and anaerobic streptococci.
2. The treatment of septicaemia, bacteraemia, peritonitis, brain abscess, necrotising pneumonia, osteomyelitis, puerperal sepsis, pelvic abscess, pelvic cellulitis, and post-operative wound infections from which pathogenic anaerobes have been isolated.
3. Urogenital trichomoniasis in the female (trichomonal vaginitis) and in the male.
4. Bacterial vaginosis (also known as non-specific vaginitis, anaerobic vaginosis or Gardnerella vaginitis).
5. All forms of amoebiasis (intestinal and extra-intestinal disease and that of symptomless cyst passers).
6. Giardiasis.
7. Acute ulcerative gingivitis.
8. Anaerobically-infected leg ulcers and pressure sores.
9. Acute dental infections (e.g. acute pericoronitis and acute apical infections).
Consideration should be given to official guidance on the appropriate use of antibacterial agents.
Pharmacotherapeutic group: Antibacterials for systemic use, ATC code: J01X D01
Эдгил is active against a wide range of pathogenic micro-organisms notably species of Bacteroides, Fusobacteria, Clostridia, Eubacteria, anaerobic cocci and Gardnerella vaginalis. It is also active against Trichomonas, Entamoeba histolytica, Giardia lamblia and Balantidium coli.
Эдгил is rapidly and almost completely absorbed on administration of Эдгил tablets; peak plasma concentrations occur after 20 min to 3 hours.
The half-life of Эдгил is 8.5 ± 2.9 hours. Эдгил can be used in chronic renal failure; it is rapidly removed from the plasma by dialysis. Эдгил is excreted in milk but the intake of a suckling infant of a mother receiving normal dosage would be considerably less than the therapeutic dosage for infants.
Regular clinical and laboratory monitoring (especially leukocyte count) are advised if administration of Эдгил for more than 10 days is considered to be necessary and patients should be monitored for adverse reactions, such as peripheral or central neuropathy (such as paraesthesia, ataxia, dizziness, convulsive seizures).
Эдгил should be used with caution in patients with active or chronic severe peripheral and central nervous system disease due to the risk of neurological aggravation.
The elimination half-life of Эдгил remains unchanged in the presence of renal failure. The dosage of Эдгил therefore needs no reduction. Such patients however retain the metabolites of Эдгил. The clinical significance of this is not known at present.
In patients undergoing haemodialysis, Эдгил and metabolites are efficiently removed during an eight hour period of dialysis. Эдгил should therefore be re-administered immediately after haemodialysis.
No routine adjustment in the dosage of Эдгил need be made in patients with renal failure undergoing intermittent peritoneal dialysis (IDP) or continuous ambulatory peritoneal dialysis (CAPD).
Эдгил is mainly metabolised by hepatic oxidation. Substantial impairment of Эдгил clearance may occur in the presence of advanced hepatic insufficiency.
Significant cummulation may occur in patients with hepatic encephalopathy and the resulting high plasma concentrations of Эдгил may contribute to the symptoms of the encephalopathy. Эдгил should therefore, be administered with caution to patients with hepatic encephalopathy. The daily dosage should be reduced to one third and may be administered once daily.
Patients should be warned that Эдгил may darken urine.
Due to inadequate evidence on the mutagenicity risk in humans , the use of Эдгил for longer treatment than usually required should be carefully considered.
Cases of severe hepatotoxicity/acute hepatic failure, including cases with a fatal outcome with very rapid onset after treatment initiation in patients with cockayne syndrome have been reported with products containing Эдгил for systemic use. In this population, Эдгил should therefore be used after careful benefit-risk assessment and only if no alternative treatment is available. Liver function tests must be performed just prior to the start of therapy, throughout and after end of treatment until liver function is within normal ranges, or until the baseline values are reached. If the liver function tests become markedly elevated during treatment, the drug should be discontinued.
Patients with Cockayne syndrome should be advised to immediately report any symptoms of potential liver injury to their physician and stop taking Эдгил.
There is a possibility that after Trichomonas vaginalis has been eliminated a gonococcal infection might persist.
Patients should be warned about the potential for drowsiness, dizziness, confusion, hallucinations, convulsions or transient visual disorders, and advised not to drive or operate machinery if these symptoms occur.
For oral administration.
Эдгил tablets should be swallowed, without chewing, with half a glassful of water during or after meals.
Prophylaxis against anaerobic infection:
Chiefly in the context of abdominal (especially colorectal) and gynaecological surgery.
Adults: 400 mg 8 hourly during 24 hours immediately preceding operation followed by postoperative intravenous or rectal administration until the patient is able to take tablets.
Children < 12 years: 20-30mg/kg as a single dose given 1-2 hours before surgery
Newborns with a gestation age < 40 weeks: 10mg/kg body weight as a single dose before operation
Anaerobic infections:
The duration of a course of Эдгил treatment is about 7 days but it will depend upon the seriousness of the patient's condition as assessed clinically and bacteriologically.
Treatment of established anaerobic infection:
Adults: 800 mg followed by 400 mg 8 hourly.
Children > 8 weeks to 12 years of age: The usual daily dose is 20-30 mg/kg/day as a single dose or divided into 7.5 mg/kg every 8 hours. The daily dose may be increased to 40 mg/kg, depending on the severity of the infection. Duration of treatment is usually 7 days.
Children < 8 weeks of age: 15 mg/kg as a single dose daily or divided into 7.5 mg/kg every 12 hours.
In newborns with a gestation age <40 weeks, accumulation of Эдгил can occur during the first week of life, therefore the concentrations of Эдгил in serum should preferable be monitored after a few days therapy.
