Product Details

FUSIDIC ACID

An antibiotic isolated from the fermentation broth of Fusidium coccineum. It acts by inhibiting translocation during protein synthesis.

Indication

For the treatment of bacterial infections.

Associated Conditions

• Conjunctivitis, Bacterial
• Mild Atopic dermatitis
• Mild Dermatitis caused by Staphylococcus aureusis
• Moderate Atopic dermatitis
• Moderate Dermatitis caused by Staphylococcus aureusis

Pharmacodynamics

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.

Mechanism of action

Fusidic 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.

Absorption

Sodium fusidic acid tablets have a 91% oral bioavailability. Absorption of the film-coated tablets is complete when compared to a solution, however oral absorption is variable. Oral fusidic acid hemihydrate (suspension) achieved a 22.5% bioavailability in pediatric patients following a 20 milligram/kilogram dose.

Volume of distribution

Metabolism

Metabolites include dicarboxylic ester/acid, 3-keto fusidic acid, hydroxy fusidic acid, glucuronide fusidic acid and a glycol metabolite.
