Fusidine - General Information
An antibiotic isolated from the fermentation broth of Fusidium coccineum. (From Merck Index, 11th ed) It acts by inhibiting translocation during protein synthesis.
Pharmacology of Fusidine
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.
Additional information about Fusidine
Fusidine Indication: For the treatment of bacterial infections.
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.
Drug Interactions: Amprenavir The protease inhibitor increases the effect and toxicity of fusidic acid
Fosamprenavir The protease inhibitor increases the effect and toxicity of fusidic acid
Nelfinavir The protease inhibitor increases the effect and toxicity of fusidic acid
Ritonavir The protease inhibitor increases the effect and toxicity of fusidic acid
Saquinavir The protease inhibitor increases the effect and toxicity of fusidic acid
Atorvastatin Increased risk of myopathy/rhabdomyolysis
Simvastatin Increased risk of myopathy/rhabdomyolysis
Indinavir Indinavir increases the effect and toxicity of fusidic acid
Food Interactions: Take with food to reduce irritation.
