ABSTRACT ObjectiveTo study the bioequivalence between lansoprazole tablets and  capsules。MethodPlasma samples were extracted by liquid liquid extraction,and HPLC was used to assay the lansoprazole concentration in plasma。Eighteen healthy human volunteers were divided randomly into 2 groups,and a crossover,single oral dose of lansoprazole at the dose of 30 mg of tested tablets and reference capsules were delivered,respectively。ResultAUC0t,AUC0,Cmax,tmax,t1/2of test tablets and reference capsules were (4.70±0.57)mg·h·L-1,(5.10±0.58)mg·h·L-1,(1.33±0.10)mg·L-1,(2.5±0.1)h,(2.2±0.4)h,and (4.62±0.59)mg·h·L-1,(4.98±0.63)mg·h·L-1,(1.32±0.08)mg·L-1,(2.5±0.1)h,(2.0±0.2)h,respectively。The bioavailability F1 and Fof test tablets vs reference capsules were(102.2±10.1)% and (103.1±9.2)% (n=18)。Main pharmacokinetic parameters between test tablets and reference capsules showed no statistical diference based on analysis of variance(P>0.05)。ConclusionThe test tablets and reference capsules are bioequivalent。
