| Abstract: | Objective To evaluate the relative bioavailability and bioequivalence between two kinds of alfuzosin hydrochloride sustained-release tablets.Methods The self-made sustained-release tablets or reference formulation were given orally to 20 healthy volunteers in a two-crossover test.Drug concentrations in plasma were determined by LC-MS-MS.Results The main pharmacokinetic parameters of the self-made sustained-release tablets and reference formulation were as follows：Cmax was（16.8±5.9）and（17.5±5.7） ng/ml;Tmax was（4.1±1.5） and（4.5±1.2） h;t1/2 was（8.5±1.7） and（8.6±1.8） h,AUC（0-48h） was（208±61） and（210±56） ng·h/ml,AUC（0-∞） was（221±64） and（224±61） mg·h/ml.The relative bioavailability was（101.5± 24.1）%.Conclusion The test preparation is bioequivalent to the reference preparation. |
