Rcifax general information
What is Rcifax used for?
Rcifax tablets 400mg are used to treat bacterial infection of the intestines that causes travellers' diarrhoea in adults, when the diarrhoea is not accompanied by fever, blood in the stools, or 8 or more unformed (soft or liquid) stools in the last 24 hours. Rcifax tablets 400mg are only effective against non-invasive bacteria like E. coli (Escherichia coli) and not against invasive bacteria including Campylobacter, Salmonella and Shighella that cause more serious dysentery-like diarrhoea. Rcifax 400 cannot be used to treat other infections as it is not absorbed into the blood and therefore, only acts locally in the gastrointestinal tract to kill local bacteria. Rcifax tablets 400mg are also used to treat hepatic encephalopathy to reduce loss of brain function due to liver damage leading to build-up of toxins in the blood.
How does Rcifax work?
Rcifax tablets 400mg contain rifaximin, a locally acting antibiotic belonging to the rifamycin class of antibiotics. Rifaximin in Rcifax tablets 400mg works by binding to the bacterial enzyme DNA-dependent RNA polymerase and this action inhibits bacterial RNA synthesis, which prevents RNA transcription and thereby the production of bacterial proteins. A certain type of E.Coli bacteria, known as enterotoxigenic, is the most common cause of travellers' diarrhoea and is usually ingested in contaminated food and water. It produces a toxin that irritates the intestine resulting in diarrhoea but no inflammation. Rcifax tablets 400mg reduce symptoms of travellers' diarrhoea including watery stools, vomiting, stomach cramps and bloating.
