药理
Indication | For the treatment of uncomplicated urinary tract infections (acute cystitis) in women due to susceptible strains of Escherichia coli and Enterococcus faecalis. |
Pharmacodynamics | Fosfomycin is a broad spectrum antibiotic that concentrates in kidney and bladder and is used to treat uncomplicated urinary tract infections. Fosfomycin also reduces nephrotoxicity and ototoxicity of platinum-containing anti-tumor agents. |
Mechanism of action | Fosfomycin is a phosphoenolpyruvate analogue produced by Streptomyces that irreversibly inhibits enolpyruvate transferase (MurA), which prevents the formation of N-acetylmuramic acid, an essential element of the peptidoglycan cell wall. |
Absorption | Fosfomycin tromethamine is rapidly absorbed following oral administration and converted to fosfomycin. Oral bioavailability under fasting conditions is 37%. When given with food, oral bioavailability is reduced to 30% |
Volume of distribution |
|
Protein binding | 0% (not bound to plasma proteins) |
Metabolism |
