How does Rifaximin (Rixmin) 400mg work?


Rixmin 400 mg tablet and its active ingredient, Rifaximin, is a broad spectrum bactericidal oral antibiotic which has activity against enteric pathogens including gram-positive and gram-negative aerobic and anaerobic bacteria.

Rifaximin is non-absorbable, it reaches high concentrations within the gastrointestinal lumen, allowing it to work effectively on various gastrointestinal diseases without systemic effects. It has a very low incidence of bacterial mutation and drug resistance to Rifaximin in extra-intestinal bacteria. However, long-term use of Rifaximin can result in resistant bacterial mutants in the enteric system.

  • Concomitant administration of P-glycoprotein inhibitors such as cyclosporine with rifaximin can substantially augment the systemic exposure to rifaximin and can lead to toxicity.
  • Rifaximin is contraindicated to patients with severe hepatic impairment: There is increased systemic exposure to rifaximin in patients with severe hepatic impairment. Therefore, caution should be exercised when administering rifaximin in patients with severe hepatic impairment.
