Fidaxomicin(OPT-80; PAR-101) is a?new class of narrow spectrum macrocyclic antibiotic drug.

Fidaxomicin(OPT-80; PAR-101) is a?new class of narrow spectrum macrocyclic antibiotic drug, selective eradication of pathogenic Clostridium difficile with minimal disruption to the multiple species of bacteria.Bacterial Infection Approved(In Vitro):Fidaxomicin selectively eradicates pathogenic Clostridium difficile with minimal disruption to the multiple species of bacteria that make up the normal, healthy intestinal flora.Fidaxomicin is not inhibitory to commonly cultured bowel commensals (MIC90 >1024?μg/mL).(In Vivo):Fidaxomicin (0-5 mg/kg, Orally, once a day for 5 days) completely prevents the lethality of the animals and prevents the occurrence of relapses in a hamster model for pseudomembranous colitis.

Fidaxomicin (0-5 mg/kg, Orally, once a day for 5 days) completely prevents the lethality of the animals and prevents the occurrence of relapses in a hamster model for pseudomembranous colitis. Animal Model:Male Golden Syrian hamsters (80-100 g, Hamster model for pseudomembranous colitis)Dosage:0.2, 1, and 5 mg/kg Administration:Orally, once a day for 5 days, beginning 8 h after infectionResult:Completely prevented the lethality of the animals. Completely prevented the development of antibiotic-induced C. difficile colitis in hamsters at doses as low as 0.2 mg/kg.
