Affected OrganismEnteric bacteria and other eubacteria
IndicationFor the treatment of bacterial infections.
PharmacologyFusidic acid is a bacteriostatic antibiotic that is often used topically in creams and eyedrops, but may also be given systemically as tablets or injections.
Mechanism of actionFusidic acid works by interfering with bacterial protein synthesis, specifically by preventing the translocation of the elongation factor G (EF-G) from the ribosome. It also can inhibit chloramphenicol acetyltransferase enzymes.
