How it works
From the US prescribing label for the same active substance (Fidaxomicin). It describes the substance, not this exact product.
Fidaxomicin is an antibacterial drug [see Microbiology ( 12.4 )].
Metabolism of fidaxomicin and formation of OP-1118 are not dependent on cytochrome P450 (CYP) enzymes.
Fidaxomicin is mainly excreted in feces.
In a food-effect study involving administration of fidaxomicin to healthy adults (N=28) with a high-fat meal versus under fasting conditions, C max of fidaxomicin and OP-1118 decreased by 21.5% and 33.4%, respectively, while AUC 0-t remained unchanged.

Safety of the active substance
