Ofloxacin Otic Solution in Patients With Otitis Media

Abstract

Drug concentrations were high in otorrhea, very low or not detected in serum, and highly variable in middle ear mucosa. Nonbiologic loss of the drug with the ear drainage through the external auditory canal and eustachian tube was probably related to the high concentration in otorrhea samples. Drug concentrations in middle ear mucosa suggest that the drug reaches the infection site.
