Fosfomycin

Fosfomycin (pronounced /fɒsfəˈmaɪsɪn/) is a broad-spectrum antibiotic that is primarily used for the treatment of urinary tract infections (UTIs). It is derived from the bacterium Streptomyces fradiae.

Etymology

The term "Fosfomycin" is derived from the chemical structure of the drug, which contains a phosphonic acid moiety (fosfo-) and a moiety derived from mycin (-mycin), a common ending for antibiotics.

Mechanism of Action

Fosfomycin works by inhibiting the enzyme MurA, which is involved in the first step of bacterial cell wall synthesis. This results in the death of the bacteria.

Usage

Fosfomycin is used to treat uncomplicated urinary tract infections caused by susceptible strains of Escherichia coli and Enterococcus faecalis. It is also used off-label for the treatment of certain types of multidrug-resistant bacterial infections.

Side Effects

Common side effects of fosfomycin include nausea, diarrhea, and headache. Serious side effects are rare but can include allergic reactions and Clostridium difficile infection.
