Active composition
Rifaximin binds to the beta-subunit of bacterial RNA polymerase, inhibiting RNA synthesis and leading to bacterial cell death.
Medical applications
Gifaxin 550 Tablet contains Rifaximin 550 mg, a broad-spectrum, non-systemic antibiotic primarily used to treat gastrointestinal infections caused by susceptible bacteria. Rifaximin acts by inhibiting bacterial RNA synthesis through binding to the beta-subunit of bacterial DNA-dependent RNA polymerase, thereby exerting a bactericidal effect. Due to its minimal systemic absorption, Gifaxin 550 is particularly effective in targeting pathogens within the gastrointestinal tract while minimizing systemic side effects.
It is commonly prescribed for the treatment of traveler’s diarrhea caused by non-invasive strains of Escherichia coli, irritable bowel syndrome with diarrhea (IBS-D), and hepatic encephalopathy to reduce the risk of recurrent episodes by decreasing ammonia-producing gut bacteria. The recommended dosage and duration of therapy depend on the specific indication and patient condition, and it is essential to adhere to prescribed guidelines to prevent the development of resistance.
Gifaxin 550 should be used with caution in patients with hypersensitivity to rifamycin derivatives and is contraindicated in those with severe liver impairment without medical supervision. Common adverse effects may include nausea, abdominal pain, and headache, though it is generally well tolerated. Consultation with a healthcare professional is advised before initiating therapy to ensure appropriate use and monitoring.
