Fidaxomicin-D7 (OPT-80-D7) is the deuterium labeled Fidaxomicin. Fidaxomicin (OPT-80), a macrocyclicRNA polymeraseinhibitor, has a narrow spectrum of activity. Fidaxomicin selectively eradicates pathogenicClostridium difficilewith minimal disruption to the multiple species of bacteria that make up the normal, healthy intestinal flora^[1][2].

Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into drug molecules, largely as tracers for quantitation during the drug development process. Deuteration has gained attention because of its potential to affect the pharmacokinetic and metabolic profiles of drugs^[1].
