Fidaxomicin D7 is intended for use as an internal standard for the quantification of Fidaxomicin by GC- or LC-mass spectrometry.

Fidaxomicin-D7 is a labelled analogue of Fidaxomicin (F335400). Fidaxomicin is a nonabsorbed macrocyclic antibiotic, and is the first antimicrobial to be approved by the FDA for the treatment of Clostridium difficile infection (CDI) in 20 years. Fidaxomicin works by inhibiting sporulation by CDI, sustaining clinical response and reducing recurrences of this pathogen.
