摘要: 目的 研究国产盐酸曲马多分散片的人体药代动力学参数和生物等效性。方法 12名健康受试者交叉口服国产盐酸曲马多分散片100mg 和进口盐酸曲马多胶囊100mg, 用HPLC法测定血浆中药物浓度。结果 两种制剂的 血药浓度曲线均符合二室模型,T1/2分别为(7.69+3.74)h和(7.66+3.41)h,血药浓度曲线下面积分别为(3100土1165)μg·h·-1和(3212土1260)μug·h·L-1,两种制剂的药代动力学参数均无显著性差异(P>0.05)。结论 两种制剂的口服生物利用度具有生物等效性。

Abstract: Aim To study the pharmacokinetics and relative bioavailabilty of tramadol hydrochloride tablet. Methods Twelve male Chinese healthy volunteers received a single oral dose of tramadol hydrochloride tablet(THT) 100mg and tramadol hydrochloride capsule(THC) 100mg in a random crossover design. Drug concentrations in plasma were determined by HPLC.Results The concentration time profile conformed to an open two-compartment model. The T1/2 and AUCo-24 of two products were (7.69+3.74) h and (7.66士3.41) h,(3100土1165) μg·h·L-1 and (3212士1260) μg·h·L-1,respectively. No significant difference was observed in pharmacokinetic parameters bet ween tested and reference preparations(P>0.05).Conclusion The THT and THC have bioequivalence.
