| 给七只成年健康奶山羊单剂量快速静注 TMP(10mg/kg)后,六小时内不同时间采血,用反相高效液相色谱(RP—HPLC)法测定血清 TMP 浓度,以残量法拟合药一时曲线得最佳方程为:C=11.64e-5.4039t+1.47e-0.757t.其它动力学参数如下:Co:13.11±2.68μg/ml;t?α:0.15±0.06h;t?β:0.94±0.19h;Vd:3.4921±1.3285L/kg;AUC:4.29±1.35h·μg/ml;K12:1.6581±1.2942h-1;k21:1.2276±0.3234h-1;k10:3.2761±0.8732h-1;Cl:2.5328±0.7768L/kg;tcp(ther):2.33h. |

| Abstract: |
| Pharmcokinetics(pk) of distribution and elimination of TMP in seven normal adult milk goats was reported.TMP was administrated intravenously by a single dose,10mg/kg of their body weight.Blood samples were collected at the diffrent time within 6 hours after the drug was given.The concentrations of TMP in the serum samples were determined by the RP-HPLC method.The serum concentration-time curves of the drug fitted a two-compartment open model: C=11.64e-5.4039t+1.47e-0.757t.The other parameter valuesof PK in milk goats are described as follow:Co:13.11±2.68μg/ml;t?α:0.15±0.06h; t?β:0.94±0.19h;Vd:3.4921±1.3285L/kg;V1:0.7891±0.1511/kg; AUC:4.29±1.35h·μg/ml;K12:1.6581±1.2942h-1; k21:1.2276±0.3234h-1;k10:3.2761±0.8732h-1; Cl:2.5328±0.7768L/kg;tcp(ther):2.33h. The results showed that TMP is a kind of short-action drug for milk goats. |
