产品描述 | Gadodiamide Hydrate (Omniscan), a nonionic Gd3+ chelate, is frequently injected i.v. into magnetic resonance imaging (MRI) to enhance contrast. |
体内活性 | Gadodiamide results in half-life of 18, 38, and 75 minutes in rats, rabbits, and monkeys, respectively. Gadodiamide is shown to be excreted rapidly, primarily through the kidneys. [1] Gadodiamide, when administered i.v. as gadodiamide injection at a dosage of 0.3 mmol/kg, is stable in vivo and that the very major part of the dose (> 99%) is excreted in urine as an unchanged complex. [2] Gadodiamide produces focal and generalized myoclonus over several hours. Gadodiamide itself produces lesions in the central cerebellar regions resembling in character and severity those produced by the gadodiamide formulation, but not others. [3] Gadodiamide travels quickly throughout the ventricular system from the lateral ventricular site of injection to the fourth ventricle and foramina of Luschka and Magendie within 2 min. [4] Gadodiamide results in transient but statistically significant decreases in aortic pressure, left ventricular pressure, indices of left ventricular contractility and relaxation, and systemic and pulmonary vascular resistance, and increases in aortic blood flow in anesthetized dogs. Gadodiamide injection produces less severe alterations in hemodynamics than gadopentetate dimeglumine. [5] |

请在以下方框中输入您的动物实验信息后点击计算,可以得到母液配置方法和体内配方的制备方法: 比如您的给药剂量是10 mg/kg,每只动物体重20 g,给药体积100 μL,一共给药动物10 只,您使用的配方为5% DMSO+30% PEG300+5% Tween 80+60% ddH2O。那么您的工作液浓度为2 mg/mL。
母液配置方法:2 mg 药物溶于 50 μL DMSO (母液浓度为 40 mg/mL), 如您需要配置的浓度超过该产品的溶解度,请先与我们联系。
体内配方的制备方法:取 50 μL DMSO 主液,加入 300 μL PEG300, 混匀澄清,再加 50 μL Tween 80,混匀澄清,再加 600 μL ddH2O, 混匀澄清。
