Learn More- 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.
Target Actions Organism AUDP-N-acetylglucosamine 1-carboxyvinyltransferase inhibitorEscherichia coli (strain K12) - 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
- 136.1 ±44.1 L
- Protein binding
0% (not bound to plasma proteins)
- Metabolism
No transformation, excreted unchanged
- Route of elimination
Fosfomycin is excreted unchanged in both urine and feces.
- Half-life
5.7 (± 2.8) hours. The elimination half-life is 40 hours in anuric patients undergoing hemodialysis.
- Clearance
- 16.9 +/- 3.5 L/hr

Drug Interaction Unlock Additional DataAbacavir Fosfomycin may decrease the excretion rate of Abacavir which could result in a higher serum level. Acarbose Acarbose may decrease the excretion rate of Fosfomycin which could result in a higher serum level. Aceclofenac Aceclofenac may decrease the excretion rate of Fosfomycin which could result in a higher serum level. Acemetacin Acemetacin may decrease the excretion rate of Fosfomycin which could result in a higher serum level. Acenocoumarol The risk or severity of bleeding can be increased when Fosfomycin is combined with Acenocoumarol. Acetaminophen Acetaminophen may decrease the excretion rate of Fosfomycin which could result in a higher serum level. Acetazolamide Acetazolamide may increase the excretion rate of Fosfomycin which could result in a lower serum level and potentially a reduction in efficacy. Acetylsalicylic acid Acetylsalicylic acid may decrease the excretion rate of Fosfomycin which could result in a higher serum level. Aclidinium Fosfomycin may decrease the excretion rate of Aclidinium which could result in a higher serum level.
