摘要：目的:研究亚硒酸钠与丹参注射液联合应用的抗血栓作用,寻求两药配伍使用的最佳剂量。方法:采用L9(34)的正交设计方法,考察药物对下腔静脉结扎法形成血栓的影响。结果:亚硒酸钠与丹参注射液最佳剂量组合为亚硒酸钠高剂量与丹参注射液中剂量。结论:亚硒酸钠高剂量(1×10-3 g/kg)与丹参注射液中剂量(3.75g/kg)伍用抗血栓效果最佳。

摘要：Aim To evaluate the pharmacokinetics and bioequivalence of domestic pantoprazole sodium enteric-coated tablets as compared with imported pantoprazole enteric-coated tablets. Methods This was an open randomized, two periods cross over study on twenty healthy male volunteers. The pantoprazole concentrations in plasma after an oral dose of 40 mg pantoprzaole preparations were determined by a HPLC-UV method. Non-compartmental method was used for the calculation of pharmacokinetic parameters. Logarithm-transformed Cmax and A UC were analyzed by the analysis of variance （ANOVA） with 90% confidence intervals. Results The main pharmacokinetics parameters of domestic pantoprazole sodium enteric-coated tablets and imported pantoprazole sodium enteric-coated tablets were as following： Cmax （3610 ± 956）, （3466 ± 1209） ng·mL^-1, tmax （3.00 ± 0.40）, （3.00 ± 0.46） h, AUC0-t （8140 ± 5065）, （8390 ± 5474） ng·h·mL^-1, AUC0-∞ （8293 ± 5094）, （8625 ± 5606） ng·h·mL^-1, t1/2 （1.61 ± 0.28）, （1.85 ± 0.27） h, respectively. Conclusion Domestic pantoprazole sodium enteric-coated tablets were bioequivalent with the imported pantoprazole sodium enteric-coated tablets.
