Up to one third of uropathogens are resistant to ampicillin and sulfonamides, but the majority are susceptible to trimethoprim-sulfamethoxazole (85 to 95 percent) and fluoroquinolones (95 percent).3,11, In view of the limited spectrum of causative organisms and their predictable susceptibility, urine cultures and susceptibility testing add little to the choice of antibiotic for the treatment of acute uncomplicated cystitis in young women. However, if there is only a small number of non-pathogenic organisms present, then the infection may not be clinically significant. what does this means? Studies using 3 g of amoxicillin, 400 mg of trimethoprim (Proloprim), two to three double-strength trimethoprim-sulfamethoxazole tablets, 800 mg of norfloxacin (Noroxin), 125 mg of ciprofloxacin (Cipro) or 200 mg of ofloxacin (Floxin) have confirmed that single-dose therapy is highly effective in the treatment of acute uncomplicated cystitis, with cure rates ranging from 80 to 99 percent.3, Fosfomycin tromethamine (Monurol) can be given as a single oral 3-g sachet for the treatment of acute uncomplicated UTIs.
