Abstract:
Objective:To study the relative bioavailability and pharmacokinetics of salbutamol orally disintegrating tablet in 18 healthy male volunteers.Methods:A single dose of 8 mg of salbutamol orally disintegrating tablet was administered in a randomized crossover way in 18 volunteers and the plasma concentrations of salbutamol were determined by HPLC.The pharmacokinetic parameters were calculated with 3P97 pharmacokinetic program and the bioavailability was evaluated.Results:The concentration-time curve of two preparations fitted two compartment model.The peak plasma levels(cmax) of salbutamol orally disintegrating tablet and market of salbutamol were 17.48?5.52 and 16.60?6.21 ng/ml,respectively.The peak time(Tmax) were 2.47?1.04 and 2.03?1.17h and AUC(0-24) were 127.34?32.66 and 131.42?37.73 ng?h/ml,respectively,The relative bioavailability of salbutamol orally disintegrating tablet was 98.76%?12.92%.Conclusion:The results of two one-side tests suggest that salbutamol orally disintegrating tablet is bioequivalent to the market tablet of salbutamol.
