Abstract:
OBJECTIVE:To study the relative bioavailability and pharmacokinetics of salbutamol sulfate orally disinte?grating tablets.METHODS:A single dose of8mg salbutamol sulfate orally disintegrating tablets or commercial salbutamol tablets was administered in a randomized crossover design in18volunteers and the plasma concentrations of salbutamol were determined by HPLC.The pharmacokinetic parameters were calculated with3p97pharmacokinetic program and the bioequiv?alency was evaluated.RESULTS:The concentration-time curve of two preparations fitted to two-compartment model.The peak plasma levels(C max )of salbutamol sulfate orally disintegrating tablet and commercial salbutamol sulfate tablet were(17.65?6.48)ng/ml and(16.60?6.21)ng/ml,respectively.The peak time(T max )were(1.92?1.18)h and(2.03?1.17)h and AUC 0～24 were(127.23?32.41)ng/(h?ml)and(131.42?37.73)ng/(h?ml),respectively.The relative bioavailability of salbu_ tamol sulfate orally disintegrating tablet was(99.32?15.58)%.CONCLUSION:The results of two one-side tests suggests that salbutamol sulfate orally disintegrating tablet is bioequivalent to the commercial salbutamol tablet.
