Rifamycin SV sodium

Rifamycin SV is a broad-spectrum semisynthetic antimicrobial agent of the rifamycin group.


Rifamycin SV inhibits selective (E. coli, B. subtilis) bacterial DNA-dependent RNA polymerase by binding to the polymerase β-subunit, a mechanism similar to rifabutin. It acts as a selective cytochrome P450 3A4 inducer. It has limited oral absorption that is active against gram-positive bacteria and is moderately active against gram-negative organisms.
