产品描述 | Cimetropium Bromide is a mAChR antagonist used for long-term treatment of irritable bowel syndrome. |
体外活性 | Cimetropium decreases the labeled ACh release induced by electrical field stimulation under the muscarinic autoinhibition blocked-condition, in the superfusion experiments of the preparation which has been preloaded with labeled choline [2]. Cimetropium has a potent antimuscarinic effect in inhibition of contraction of longitudinal muscle preparations. Cimetropium Bromide behaves as a competitive antagonist of muscarinic-mediated contractions in isolated colonic preparations from both species, with affinity values (pA2) ranging between 7.41 and 7.82 [1]. |
体内活性 | Cimetropium Bromide (10-100 μg/kg) counteracts colonic motor response to neostigmine administration (ID50: 27.9 μg/kg); both tonic and phasic components of contractile response are affected. Cimetropium is a potent inhibitor of large bowel motility evoked by both exogenous and endogenous stimuli when administered intravenously to conscious dogs provided with a colonic Thiry fistula. In a comparable range of doses (3-100μg/kg), the drug inhibits motor activity elicited by intraluminal distension [1]. |

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。
