Study on Relative Bioavailability of Cefaclor Capsules in Human Body / 中国药房

ABSTRACT

OBJECTIVE:To evaluate the relative bioavailability of2kinds of preparations of cefaclor capsules.METH?ODS:The subjects'blood concentrations were determined by HPLC at different time after administered randomly crossover with single oral dose of cefaclor testing preparation or reference preparation.The actual values of C max and T max were adopted;AUC was calculated by trapezoid planimetry;the bioequiavailability of the2preparations were evaluated by two-sides and one-side t-test.RESULTS:The AUC 0～4 of the testing preparation and reference preparation were respectively(13.44?3.06)(?g?h)/ml and(14.19?3.28)(?g?h)/ml;their respective AUC 0～∞ were(13.80?3.08)(?g?h)/ml and(14.62?3.33)(?g?h)/ml;their respective C max were(11.65?2.39)?g/ml and(12.37?2.41)?g/ml;their respective t max were(0.57?0.24)h and(0.66?0.19)h.The relative bioavailability of testing preparation was(95.62?13.51)%.CON?CLUSION:The2preparations are bioequivalent.
