3-keto Fusidic acid is a metabolite of fusidic acid. Fusidic acid is a bacteriostatic antibiotic that is often used topically in creams and eyedrops, but may also be given systemically as tablets or injections. The global problem of advancing antimicrobial resistance has led to a renewed interest in its use recently. (Wikipedia)
