Sequential intravenous-oral administration of ciprofloxacin vs ceftazidime in serious bacterial respiratory tract infections.
The efficacy and safety of sequential intravenous/oral ciprofloxacin in moderate to severe respiratory tract infections (RTI) were compared with those of ceftazidime in a prospective clinical trial. Sixty-six patients received IV ciprofloxacin (200 to 300 mg twice daily), followed by oral ciprofloxacin (500 mg twice daily). Fifty-six patients received intravenous ceftazidime (1 to 2 g two to three times daily). Ciprofloxacin was as effective as ceftazidime and produced a 91 percent clinical cure rate. Significantly more pretreatment bacterial isolates were susceptible to ciprofloxacin, and ciprofloxacin had a significantly higher rate of sputum bacterial eradication than did ceftazidime. Ciprofloxacin showed broad in vitro antibacterial activity with particularly low minimal inhibitory concentrations for Gram-negative organisms. Ciprofloxacin was well tolerated; there were few adverse effects. Ciprofloxacin was an effective and well-tolerated treatment for severe RTI that had the advantages of broad in vitro antibacterial activity, twice-daily dosing, and sequential availability in an intravenous and oral formulation.
