摘要
目的:研究苦参素片在健康人体内的药动学及生物等效性.方法:22名健康男性志愿者随机交叉单剂量口服苦参素片或胶囊0.3g,血样加入内标(西咪替丁)经预处理后采用高效液相色谱-质谱法测定药物浓度,检测离子为m/z 265(苦参素)、m/z253(内标).结果:苦参素片与胶囊的t1/2分别为(2.30±1.09)、(1.90±0.58)h;tmax分别为(1.86±0.74)、(1.68±0.55)h;Cmax分别为(525.09±208.94)、(530.32±202.04)ng/ml;AUC0~11分别为(2 048.5±749.4)、(2 042.0±743.0)(ng·h)/ml;AUC0~∞分别为(2 163.2±783.1)、(2 136.4±792.1)(ng·h)/ml;苦参素片的相对生物利用度为(101.06±9.41)%.结论:苦参素片与胶囊具有生物等效性.
OBJECTIVE: To study the endosomatic pharmacokinetics and bioequiavailability of kushenin tablets in health adults. METHODS: The blood concentrations of the blood samples taken from 22 healthy volunteers were determined by HPLC-MS after a single oral 0.3g kushenin (either tablet or capsule) dose and pretreatment with.the internal standard (cimetidine) with m/z 265 (kushenin) taken as the detection ions and m/z 253 as the internal standard. RESULTS: The main pharmacokinetic parameters of the tablet and capsule of kushenin were as follows: t 1/2 stood at (2.30± 1.09) h and (1.90± 0.58) h, respectively; t max stood at (1.86± 0.74) h and (1.68± 0.55) h, respectively; Cmax stood at (525.09± 208.94)ng/ml and (530.32 ± 202.04) ng/ml, respectively; A UC0-11 stood at(2 048.5±749.4) (ng · h)/ml and (2 042.0 ± 743.0) (ng · h)/ml, respectively; AUC0-∞ stood at(2 163.2± 783.1) (ng · h)/ml and (2 136.4±792.1) (ng · h)/ml, respectively. The relative bioavailability of the kushenin tablet stood at (101.06± 9.41) %. CONCLUSION:The tablet and capsule of kushenin were bioequivalent.
