Bioequivalence of two paediaric ibuprofen suppositories in healthy volunteers

  • Department of Pharmacy, General Hospital of Beijing Military Command of PLA, Beijing100700, China

  • Received Date: 2009-03-16
  • Objective :To develop a LC-MS-MS assay for the determination of ibuprofen in human serum and to investigate the pharmacokinetics and bioequivalence of two preparation in Chinese healthy volunteers. Methods : A single per rectum dose of 50 mg ibuprofen test suppositories and reference suppositories was given to 20 healthy male volunteers in a randomized double cross-over design.Ibuprofen concentration were determined by LC-MS-MS assay,and pharmacokinetic parameters were calculated with DAS2.0 practical pharmacokinetics program. Results :The calibration curve was linear over the range of 0.05～6.4 mg/L.The main pharmacokinetic parameters of test suppositories and reference suppositories were as follow: t1/2(2.77±0.65) and(3.02±0.99) h,ρmax(2.148±0.643) and(2.013±0.844) mg/L,tmax(3.2±0.7) and(3.1±0.5) h,AUC0-12(11.37±3.56) and(11.30±4.62)mg·h/L. Conclusion :The method applied was convenient,accurate and specific,and the statistical analysis showed that the test and reference preparation bioequivalent.
