title: Single-dose pharmacokinetics of ofloxacin during continuous venovenous hemofiltration in critical care patients.
abstract: BACKGROUND
  Ofloxacin is a quinolone administered to patients with severe infections. Pharmacokinetic data on ofloxacin in critically ill patients on renal replacement therapy are sparse and conflicting.
  
  
  METHODS
  Eight patients with anuric acute renal failure were administered 400 mg of ofloxacin intravenously. The pharmacokinetics of ofloxacin was analyzed during continuous venovenous hemofiltration (CVVH) with a high-flux polysulfone membrane. Serum and ultrafiltrate levels of ofloxacin were measured by means of high-performance liquid chromatography.
  
  
  RESULTS
  Mean serum ofloxacin concentration peak was 5.5 +/- 0.7 mg/L. Elimination half-life, hemofiltration clearance, and total removal were 2.8 +/- 0.5 hours, 89.9 +/- 4.5 mL/min, and 76.9% +/- 7.1%, respectively.
  
  
  CONCLUSIONS
  Ofloxacin is significantly and rapidly eliminated by CVVH with a high-flux polysulfone membrane.
