vasopressin receptor

目标剂量为4.0微克，因为该剂量符合抗利尿作用的标准，因此在安全性研究中，所有受试者均服用8.0微克。输注4.0和8.0微克后，中位消除半衰期分别为4.72（范围3.99-6.53）小时和3.85（范围3.04-11.08）小时。输注4微克后，血浆清除率和稳态分布体积估计为0.88（SD 0.24）ml x min（-1）x kg（-1）和326（SD 68）ml x kg（-1）]。在最高剂量（8微克）后，相应的估计值分别为0.86（SD 0.32）ml x min（-1）x kg（-1）和299（SD 81）ml x kg（-1）。输注4.0和8.0微克F992后产生显著不同的最大平均尿液渗透压（P=0.033）（534（SD 318）vs 732（SD 189）mOsmol x kg（-1））。达到这些值的中位时间在最高剂量下有延长的趋势，但没有达到统计学意义。研究期间未观察到严重不良事件。[1]

Eight healthy male volunteers participated in this open study consisting of two parts: a dose titration study and a safety study. In the dose titration study ascending doses of F992 were administered to volunteers in pairs in order to find a dose that within 1 h after the infusion, in both subjects, caused a reduction of the urine flow rate to below 5 ml x min(-1) (target dose). Subsequently, this target dose was administered to all volunteers. In the safety study the target dose was doubled and given to all volunteers. On each study occasion, in both study parts, the subjects were orally overhydrated with water. F992 was administered as i.v. infusion approximately 1.5 h after the start of the hydration procedure. Throughout the study days, blood was sampled for determination of plasma concentrations of F992 and for safety evaluation. Urine was collected at intervals in order to estimate flow rate and osmolality.[1]

请根据您的实验动物和给药方式选择适当的溶解配方/方案：
1、请先配制澄清的储备液(如：用DMSO配置50 或 100 mg/mL母液(储备液));
2、取适量母液，按从左到右的顺序依次添加助溶剂，澄清后再加入下一助溶剂。以 下列配方为例说明 (注意此配方只用于说明，并不一定代表此产品 的实际溶解配方):
10% DMSO → 40% PEG300 → 5% Tween-80 → 45% ddH2O (或 saline);
假设最终工作液的体积为 1 mL, 浓度为5 mg/mL: 取 100 μL 50 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中，混合均匀/澄清；向上述体系中加入50 μL Tween-80，混合均匀/澄清；然后继续加入450 μL ddH2O (或 saline)定容至 1 mL；
3、溶剂前显示的百分比是指该溶剂在最终溶液/工作液中的体积所占比例;
4、 如产品在配制过程中出现沉淀/析出，可通过加热(≤50℃)或超声的方式助溶;
