Abstract The pharmacokinetics of ofloxacin following a single 200 mg oral dose were studied in twelve healthy elderly volunteers. Relevant pharmacokinetic parameters were analysed by both noncompartmental and compartmental models. In compartmental analysis, the data on plasma concentrations was best described by an open two-compartment model. A zero-order absorption behaviour was found in some volunteers. The terminal half-lives were slightly prolonged and ranged from 6.2–11.6 h. A linear relationship was found between the renal clearance of the drug and the estimated creatinine clearance. Computer predictions of a multiple 200 mg dose regimen showed no important accumulation of ofloxacin. The recommendation of some authors that, in general, ofloxacin dosage may be halved in the elderly could not be confirmed. This has to be determined through further clinical experience in elderly ill subjects.
