설명

일반 설명

Chemical structure: macrolide

애플리케이션

Rifaximin is a semisynthetic analog of rifamycin with poor absorptivity. It selectively inhibits (E. coli, B subtilis) bacterial DNA-dependent RNA polymerase by a mechanism similar to rifabutin, β subunit binding. It is effective against aerobic and anaerobic Gram-positive and Gram-negative bacteria. It is active against species of Staphylococcus, Streptococcus and Enterococcus. It is less active against species of Enterobacteriaceae. Rifaximin is a non-systemic, gastrointestinal site-specific antibiotic. It has a pyridoimidazole ring, making it non-absorbable. Rifaximin is a pregnane X receptor (PXR) activator.
