  Pharmacokinetics, disposition and biotransformation of [14C]-radiolabelled valsartan in healthy male volunteers after a single oral dose

  摘要：

  1. The disposition of valsartan, a potent angiotensin II receptor antagonist, was investigated in six healthy male volunteers. They each received a single oral dose of 80 mg of a C-14-labelled preparation as a neutral buffered solution.2. Peak concentrations of radioactivity and valsartan in plasma measured Ih after dosing showed rapid onset of absorption. The results of this study combined with other available data indicate that at least 51% of the dose was absorbed.3. Valsartan was the predominant radioactive compound in plasma. Elimination of valsartan and radioactivity was fast and multiexponential. beta-Half-lives of 6 +/- 1 h were observed. In a terminal elimination phase, low radioactivity levels decreased with a half-life of 81 +/- 33 h. A minor, pharmacologically inactive metabolite (valeryl-4-hydroxy-valsartan; M1) was detected in the plasma at rime points later than 2 h after dosing, representing approximately 11% of the AUC((24 h)) of plasma radioactivity.4. The bulk of the dose was excreted within 4 days. The total excretion within 7 days amounted to 99 +/- 1% of dose. Faecal excretion was predominant (86 +/- 5% of dose). Valsartan was largely excreted unchanged (81 +/- 5% of the dose in the excreta). The predominant clearance mechanism appeared to be direct elimination via bile. 5. An inactive metabolite, M1, was formed by oxidative biotransformation and accounted for 9 +/- 3% of the dose in the excreta.
