摘要: 目的: 考察注射用复方氨苄西林钠的药代动力学特征。 方法: HPLC法检测注射家兔后不同时间血浆的氨苄西林与丙磺舒药代动力学参数。 结果: 以氨苄西林钠计,注射用复方氨苄西林钠300 mg/kg组能够显著的增加氨苄西林半衰期,由(23±10)min增至(31±15) min,AUC由(8．5±0．9)mg/(h·mL)增至(6．2±0．8) mg/(h·mL),注射用复方氨苄西林钠120 mg/kg组氨苄西林AUC由(2．8±0．9)mg/(h·mL)增至(5．7±1．0)mg/(h·mL),注射用复方氨苄西林钠50 mg/kg组氨苄西林AUC由(0．7±0．2)mg/(h·mL)增至(1．5±0．3)mg/(h·mL)(P＜0．05或P＜0．01)。 结论: 注射用复方氨苄西林钠具有增强注射用氨苄西林钠活性的作用。Abstract: Objective:To observe the characteristics of the pharmacokinetics of compound ampicillin sodium for injection.Meth- otis:The pharmacokinetics of ampieillin and probenecid in six rabbits after injection were measured by HPLC. Results: On calculation of quantity of ampieillin sodium,300 mg/kg compound ampicillin sodium increased the half life of ampicillin from(23±10)to(31±15)min and the value of A UC from(8.5±0.9 )to(6.2±0.8)mg/(h·mL),120 mg/kg compound ampicillin sodium increased the value of AUC from(2.8±0.9)to(5.7±1.0)mg/(h·mL),50 mg/kg compound ampicillin sodium increased the value of AUC from(0.7±0.2)to(1.5±0.3)mg/(h·mL). Conclusion: Compound ampicillin sodium for injection can increase the activity of ampicillin sodium.
