title: [Study on determination of desloratadine in human serum and its pharmacokinetics by HPLC/MS].
abstract: To study the determination of desloratadine in human serum and its pharmacokinetics in healthy volunteers.
  
  
  
  A single oral dose of 10 mg desloratadine was given to 18 healthy volunteers. The serum concentrations of desloratadine were determined by HPLC-MS assay. The pharmacokinetics parameters of desloratadine tablets were calculated with program 3P97.
  
  
  
  The main pharmacokinetics parameters of desloratadine tablets were as followsút(max)(1.611 +/-0.366)h, C(max) (4.455+/-1.990)microg x L(-1), AUC(0-t) (58.50+/-21.34)microg x L(-1) x h(-1), AUC(0-infinity) (60.59+/-22.32)microg x L(-1) x h(-1), t(1/2(ke)) (20.303+/-5.833)h, Ke (0.0372+/-0.0116)h(-1) and CL(0.1838+/-0.0563)L x h(-1).
  
  
  
  Desloratadine tablet is absorbed quicker in the 18 healthy volunteers than the reports and its peak blood concentration reached at 1.5 h after oral administration with t(1/2) 20 h.
