Rexigut general information
What is Rexigut used for?
Rexigut is an antibiotic used to treat bacterial infection of the intestines that causes traveler's 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.
A certain type of E.Coli bacteria (Escherichia coli), known as enterotoxigenic, is the most common cause of travelers' diarrhoea and is usually ingested in contaminated food and water. It produces a toxin that irritates the intestine resulting in diarrhoea but no inflammation.
Rexigut is only effective against non-invasive bacteria like E. coli and not against invasive bacteria (carried in the bloodstream) including Campylobacter, Salmonella and Shigella that cause more serious dysentery-like diarrhoea. Rexigut kills the bacteria that cause traveler's diarrhoea to relieve symptoms including watery stools, vomiting, stomach cramps and bloating, but 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.
How does Rexigut work?
Rexigut tablets 400mg contain rifaximin, a locally acting antibiotic belonging to the rifamycin class of antibiotics. It is a non-systemic antibiotic, which means it acts locally in the intestines and is not absorbed into the circulation. Rifaximin in Rexigut works by binding to the bacterial enzyme DNA-dependent RNA polymerase and this action inhibits bacterial RNA synthesis. This prevents RNA transcription and thereby the production of bacterial proteins, which inhibits growth of the bacteria. Rifaximin in Rexigut is effective against the bacteria that cause traveler's diarrhoea to relieve symptoms including watery stools, vomiting, stomach cramps and bloating.

Traveler's diarrhoea is characterised by diarrhoea that is not accompanied by fever, blood in the stools, or 8 or more unformed (soft or liquid) stools in 24 hours. Rexigut is not effective against invasive bacteria (carried in the bloodstream) that cause more serious dysentery-like diarrhoea. Rifaximin in Rexigut works by blocking the production of bacterial proteins, which prevents growth and spread of the bacteria. Rexigut helps reduce symptoms of travelers' diarrhoea including watery stools, vomiting, stomach cramps and bloating.
