Tissue and serum concentrations of ofloxacin in the ear region following a single daily oral dose of 400 mg.
Even after a single daily dose of 400 mg, the concentrations of ofloxacin in infected middle ear tissues are within the therapeutic range. Even 20 h after a single dose of 400 mg ofloxacin, the tissue concentrations in cartilage and cholesteatomatous matrix are in excess of the minimal inhibitory concentration for a number of pathogens, such as Staphylococcus aureus and Haemophilus influenzae. The especially high concentrations in middle ear mucosa, auricular cartilage and cholesteatomatous matrix are striking. No complications or side effects were observed during ofloxacin treatment in this study. The study demonstrates that a dose of 400 mg ofloxacin per day is an effective and patient orientated therapeutic regime for the treatment of ENT infections, particularly of ear infections.
