- 产品名称:DGM胃肠动态模拟器,动态胃消化模拟系统
- 订货号:tlyon005290
- 品牌名称:英国PBL
主要特征
- 精确复制胃混合液,剪切速率和蠕动。
- 为胃内容物提供准确的生化环境,允许进食和禁食比较不同食物类型的剂型行为。
- 与均质样品相反,具有研究多相餐食(即,真实食品和/或口服给药的药物制剂)消化能力的能力。
- 根据食物基质自动动态调整胃停留时间,酸和酶的添加量(数量和速率)以及生理过程。
- 可控制的胃排空和排泄。
- 在消化的所有阶段均可进行采样,从而可以进行实时收集和详细分析,以及针对特定隔室的建模。
- 全自动,易于使用和消毒。
- 提供有关消化过程的质量检查报告,包括停留时间,排空曲线,pH梯度,胃添加量/流速。
描述
胃肠动态模拟器,动态胃消化模型(DGM)是计算机控制的体外模拟肠道消化系统,可以模拟人胃中的消化,从而可以实时准确地预测和了解消化过程中人肠内食物或药物制剂的行为。DGM是第一个已知的体外消化模型,在单个预测系统中结合了人类胃中的内腔物质所经历的物理,机械和生化环境的新兴科学知识。
DGM完全复制了复杂的生化条件和一系列胃动力,这些因素对于预测API(活性药物成分)和口服给药剂型(例如胶囊,片剂,粉剂和液体)的生物行为至关重要。在此过程中的任何时候都可以取样,并进行分析以预测诸如营养素和药物等活性成分的摄取有效性(生物可及性)。
DGM基于多年的人类MRI研究基础,并已在商业和学术领域得到食品和制药应用的验证,为动物研究提供了一种生理,经济高效和符合道德的选择。
