Lomefloxacin clinical pharmacokinetics.
Lomefloxacin is a quinolone antibiotic with chemical and microbiological properties similar to most commercially available agents of this class. There are differences, however, between lomefloxacin and other quinolones in activity against specific micro-organisms, a situation that is typical of most antibiotic classes. The pharmacokinetics of lomefloxacin support once- or twice-daily dosage, depending on the pathogen or site of infection. This is a result of its relatively high serum concentrations and long half-life. The outstanding pharmacokinetic features of lomefloxacin are its high degree of tissue distribution, lack of significant metabolism (and, therefore, no competitive drug interactions with other metabolised drugs showing a common metabolic pathway), and good oral absorption. Like most fluoroquinolones, lomefloxacin can chelate with heavy metals. However, this interaction can be eliminated by administering lomefloxacin 2h before the cation-containing products. Dosage adjustments are required in patients with renal dysfunction. However, patients with liver disease do not require alterations in lomefloxacin dosage regimens. The safety profile, lack of significant drug interactions and convenience of administration make lomefloxacin a useful agent in specific clinical settings.
