Key words:

Uncomplicated urinary infections are a significant and growing cause of morbidity amongst young women. Commonly these infections are caused by Escherichia coli or Staphylococcus saprophyticus. Escherichia coli is resistant to several empirical antibiotics: amoxicilin, trimetoprima-sulfametozaxol and, more recently, to some more old flouroquinolons. Gemifloxacin is a flouroquinolon with an excellent in vitro activity against many community acquired bacteria which cause respiratory or urinary infections. This antibiotic has a very unique and dual action mechanism directed against girasa and topoisomerasa II DNA, which grants minimum low inhibitory concentrations against Escherichia coli, Klebsiella and S. saprophyticus species and others attacking respiratory system. Young women with uncomplicated urinary infections were evaluated in two random clinical studies; they were treated with 320 mg gemifloxacin once a day for three days. Gemifloxacin was compared to ofloxacin or ciprofloxacin in approved doses and durations and it proved to be useful with clinical success rates of 95% or more in both studies. Gemifloxacin showed to be safe and well tolerated. A dose a day is a safe and useful alternative amongst current empirical options to treat patients with uncomplicated urinary infections..

ABSTRACT

Uncomplicated urinary infections are a significant and growing cause of morbidity amongst young women. Commonly these infections are caused by Escherichia coli or Staphylococcus saprophyticus. Escherichia coli is resistant to several empirical antibiotics: amoxicilin, trimetoprima-sulfametozaxol and, more recently, to some more old flouroquinolons. Gemifloxacin is a flouroquinolon with an excellent in vitro activity against many community acquired bacteria which cause respiratory or urinary infections. This antibiotic has a very unique and dual action mechanism directed against girasa and topoisomerasa II DNA, which grants minimum low inhibitory concentrations against Escherichia coli, Klebsiella and S. saprophyticus species and others attacking respiratory system. Young women with uncomplicated urinary infections were evaluated in two random clinical studies; they were treated with 320 mg gemifloxacin once a day for three days. Gemifloxacin was compared to ofloxacin or ciprofloxacin in approved doses and durations and it proved to be useful with clinical success rates of 95% or more in both studies. Gemifloxacin showed to be safe and well tolerated. A dose a day is a safe and useful alternative amongst current empirical options to treat patients with uncomplicated urinary infections.
