A new study indicates that the drug fosfomycin may be effective for treating multidrug-resistant bacterial infections. In most European countries, the oral formulation is only approved as a 3 gram single dose for the treatment of uncomplicated cystitis; however a new study found that a dosing regimen of 6-12 grams per day divided in 3 doses is required for the treatment of systemic multi-drug-resistant bacterial infections.
