Clinical efficacy and levels of ciprofloxacin in tissue in patients with soft tissue infection

Abstract

The clinical efficacy of ciprofloxacin was evaluated with 21 patients with soft tissue infection due mainly to gram-negative aerobic bacteria. Clinical cure was noted in 16 patients (76%), and clinical improvement was noted in the remaining 5 patients (24%). In addition, levels of ciprofloxacin were measured in the sera and tissues of 11 patients. Mean concentrations in tissue averaged 1.75 times the levels in serum. Ciprofloxacin should provide serum and soft tissue concentrations above the MICs for most gram-negative aerobic bacteria.
