title: Multiple-dose pharmacokinetics of cefepime in long-term hemodialysis with high-flux membranes.
abstract: OBJECTIVE
  Among uremic patients on hemodialysis, infectious complications leading to a high incidence of morbidity and mortality are a well-documented problem. In this multi-dose study, the safety, tolerance, and pharmacokinetics of cefepime during high-flux hemodialysis were investigated and an improved dosing schedule is presented.
  
  
  METHODS
  Six long-term hemodialysis patients received 2 g cefepime i.v. at the end of hemodialysis three times per week.
  
  
  RESULTS
  Trough levels of cefepime were 23.3 +/- 7.3 mg/l and peak serum concentrations 165.6 +/- 48.7 mg/l. After 3.5 h of high-flux hemodialysis, 72.2 +/- 6.4% of cefepime was eliminated. The intradialytic half-life was 1.6 +/- 0.29 h and the interdialytic half-life 22.0 +/- 2.14 h.
  
  
  CONCLUSIONS
  A dosage of 2 g cefepime after each hemodialysis session achieved drug levels well above the minimal inhibitory concentration (MIC)90 for most of the target pathogens. Thus, the described dosing schedule is an efficient and cost saving antmicrobial therapy for severe infections in long-term hemodialysis patients with no residual renal function.
