Rifamycin Sodium Chemical Properties,Uses,Production

Chemical Properties

Dark Red Solid

Uses

Rifamycin SV Sodium (Rifaximin EP Impurity C) is a semi-synthetic antibiotic derived from Rifamycin S. (1) Antibacterial (2). Potency >900 units (dry basis).

Uses

Semi-synthetic antibiotic derived from Rifamycin S. Antibacterial. Potency >900 units (dry basis).

Biological Activity

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 is active against Gram-positive bacteria and is moderately active against Gram-negative organisms.

in vivo

Rifamycin (5 mg/day; s.c.; 3 days a week) sodium is effective in mice infected with M. tuberculosis, significantly reducing the number of viable bacteria in the body[4].
Rifamycin (12.5-25 mg/kg; peritoneal lavage) sodium can improve the survival rate of rats with experimental intraperitoneal infection and significantly reduce the number of intraperitoneal bacteria and adhesion formation[6].
Rifamycin (5-40 mg/kg; esophageal gavage; once a day, 5 days a week; 4 weeks) sodium shortens oral treatment duration in a mouse model of Mycobacterium ulcerans disease[8].
Rifamycin (0.1 mL; intraaural administration; twice daily; 10 days) sodium does not cause hearing loss in adult or weanling rats[9].
Rifamycin (1 mg i.v. bolus followed by 4 mg i.v. infusion; 70 min) sodium interferes with three major steps of Bile acid metabolism in rats with intravenous Sodium cholate (HY-N0324A) infusion, resulting in a significant decrease in bile acid uptake and excretion[10].
Rifamycin (10-160 mg/kg; s.c.; single dose) sodium is approximately 11 times less effective than Metronidazole (HY-B0318) in a mouse Bacteroides fragilis thigh infection model[11].

Animal Model:Male Wistar rats (weight 200-250 g), cecal ligation puncture (CLP)-induced intra-abdominal infection model[6]
Dosage:25 mg/kg, 12.5 mg/kg
Administration:Peritoneal lavage
Result:Improved survival from 50% in the control group to 91.7% in the 25 mg/kg group and 100% in the 12.5 mg/kg group.
Significantly reduced adhesion formation.
Showed a greater reduction in bacterial counts in peritoneal fluid (25 mg/kg).
