Overview of experience with ofloxacin in respiratory tract infection
Abstract
Ofloxacin is highly active against common respiratory pathogens including Haemophilus influenzae and Branhamella catarrhalis and has clinically applicable activity against Streptococcus pneumoniae, Staphylococcus aureus and Pseudomonas aeruginosa. Sputum, lung tissue and bronchial mucosal concentrations of ofloxacin equal or, in most cases significantly exceed the MICs of such pathogens. These in vitro attributes are reflected in the results of the worldwide ofloxacin clinical trial program which achieved overall response rates of 98% in lower respiratory tract infections, 83% in pneumonias and 87% to 95%, in open and comparative studies respectively, in patients with acute exacerbations of chronic bronchitis (CB). Overall bacterial eradication rates ranged from 70% for pneumococci and 84.5% for B. catarrhalis to 88.5% for H. influenzae. In lower respiratory infection ofloxacin gave equal or superior clinical results to amoxycillin or erythromycin therapy together with an overall bacterial eradication rate of 100%. Clinical results comparable with standard agents were also obtained in pneumonia, cure rates ranging from 77-89% at various dosages. Eradication rates proved greatest for H. influenzae (92%) and were satisfactory for Klebsiella spp. (80%), although less so for pneumococci (73%). Bacteriological eradication rates in acute exacerbations of chronic bronchitis ranged from 68% for pneumococcal infections, to 85% in B. catarrhalis and 94% in H. influenzae infections.…
How strong is the evidence?
Evidence Hub reads this as a clinical trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence.
