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?ODSThe 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?CLUSIONThe2preparations are bioequivalent.
