FAMAGYL is a nitroimidazole antibiotic medication used particularly for anaerobic bacteria and protozoal infections. An antibiotic, antiprotozoal and amebicide, it is the drug of choice for first episodes of mild-to-moderate Clostridium difficile infection.
MODE OF ACTION
FAMAGYL is selectively absorbed by anaerobic bacteria and sensitive protozoa. Once taken up by anaerobes, it is non-enzymatically reduced by reacting with reduced ferredoxin, which is generated by pyruvate oxido-reductase. Many of the reduced nitroso intermediates will form sulfinamides and thioether linkages with cysteine-bearing enzymes, thereby deactivating these critical enzymes. As many as 150 separate enzymes are affected.
In addition, FAMAGYL metabolites are taken up into bacterial DNA to form unstable molecules. This function only occurs when FAMAGYL is partially reduced. This reduction usually happens only in anaerobic and protozoal cells, so it has relatively little effect upon human cells and aerobic bacteria.
FAMAGYL is used for treating the following infections:
Bacterial vaginosis; Pelvic inflammatory disease in conjunction with other antibiotics such as ofloxacin, levofloxacin, or ceftriaxone, Anaerobic infections caused by such organisms as Bacteroides fragilis spp, Fusobacterium spp, Clostridium spp, Peptostreptococcus spp, Prevotella spp or any other anaerobes in intra-abdominal abscess. Peritonitis, diverticulitis, empysema, pneumonia, lung and brain abscess, meningitis, diabetic foot ulcer, bone and joint infections, septicemia, endometritis and endocarditis. Pseudomembranous colitis due to Clostridium difficile.
Helicobacter pylori eradication therapy as part of a multi-drug regimen in peptic ulcer disease.
Dental infection of bacterial origin such as periapical abscess, periodontal abscess, acute pericoronitis of impacted and partially erupted teeth. In this case, FAMAGYL is used in conjunction with amoxicillin.
Amoebiasis: Infections caused by Entamoeba histolytica.
Giardiasis: Infections of the small intestine caused by the ingestion of infective cysts of Giardia lamblia. Trichomoniasis: Infections caused by Trichomonas vaginalis which is a common cause of vaginitis and is the most frequently presenting new infection of common sexually transmitted diseases.
Prophylaxis for those undergoing potentially contaminated colorectal surgery or appendectomies and maybe combined with neomycin.
Crohn’s disease with colonic or perianal involvement. FAMAGYL is more effective in combination with ciprofloxacin in treating this condition.
FAMAGYL can be used in women to prevent bacterial vaginosis associated with preterm births; amongst other risk factors including the presence of cervico-vaginal fetal fibronectin.
RECOMMENDED DOSAGE AND ADMINISTRATION
Always take FAMAGYL exactly as your doctor has told you. You should check with your doctor or pharmacist if you are not sure because the dosage depends on the type of infection and how bad it is.
