摘要
目的 :研究格列吡嗪 (glipizide,Gli)片的药代动力学和相对生物利用度。 方法 :2 0名受试者单剂量口服 Gli片10 mg后 ,在规定时间取血 ,HPL C法测定血药浓度。采用统计矩方法计算药动学参数。结果 :单剂量口服 Gli试验药和参比药后的平均药动学参数分别为 :AU C0～∞ :(5 76 3± 16 13)、(5 5 5 4± 136 5 ) h· ng/ ml;Tmax:(3.0 0± 1.18)、(3.6 0± 1.72 ) h;cmax:(939.5± 2 33.3)、(819.8± 2 13.8) ng/ ml;MRT:(8.0 9± 1.6 6 )、(8.74± 2 .2 8) h;t1 /2 :(4.82 7± 1.2 2 6 )、(5 .12 3± 1.4 2 1)h;相对生物利用度 F0～ 2 4 =(10 4 .8± 15 .4 ) %。 结论 :两种制剂生物等效 ,其药动学参数无显著差异 ,并且与文献报道一致。
Objective: To study the pharmacokinetics and relative bioavailability of glipizide tablet. Methods: The glipizide concentrations in sera of 20 subjects were determined by HPLC following an oral single dose of 10 mg. The statistical moment theory was used to calculate the pharmacokinetic parameters. Results: The average pharmacokinetic parameters after oral single dose of the test drug and the reference drug were as follows: AUC 0～∞ :(5 763±1 613) and (5 554±1 365) h·ng/ml; T max :(3.00±1.18) and (3.60±1.72) h; c max :(939.5±233.3) and (819.8±213.8) ng/ml; MRT:(8.09±1.66) and (8.74±2.28) h; t 1/2 :(4.827±1.226) and (5.123±1.421) h respectively;relative bioavailability F 0～24 was (104.8±15.4)%. Conclusion:The two preparations are bioequivalent. There is no significant difference in pharmacokinetic parameters between two preparations. The results are same as those reported in references.
