一个新的九媒体系统准确地模拟了快食和食状态的肠液溶解度. 这种体外法改善了药物溶解性预测,有助于制药开发.
科学领域:
- 生物制药科学 生物制药科学
- 药物发现和开发 药物发现和开发
- 物理化学 物理化学
背景情况:
- 口服药物的吸收需要在胃肠道溶解.
- 肠道溶解度至关重要,但由于人类肠液 (HIF) 的变化,很难测量.
- 现有的模拟肠液 (SIF) 模型无法充分捕捉HIF的变化.
研究的目的:
- 为了比较基于文献的禁食 (Fa) 和食 (Fe) 状态HIF药物溶解度与新体外九介质系统 (Fa/Fe9SIF) 的值.
- 建立一种新的体外方法,用于生物等价的肠道溶解度的确定.
- 通过考虑基于人口的变化来提高药物发现和开发的预测能力.
主要方法:
- 收集了129个文献 Fa/FeHIF药物溶解度值.
- 使用新型Fa/Fe9SIF系统测量了387个模拟的肠液平衡溶解度值.
- 在统计上将Fa/Fe9SIF溶解度与Fa/FeHIF数据进行比较,并分析了一个新的溶解度相关窗口.
主要成果:
- 在Fa/Fe9SIF和Fa/FeHIF药物溶解度之间没有检测到统计学上显著的差异.
- 一个新的可溶性相关窗口涵盖了额外文献Fa/FeHIF数据集的95%.
- 观察到的溶解性行为与已确立的物理化学原理一致.
结论:
- Fa/Fe9SIF系统提供了一种新的,准确的体外方法来确定生物等价的肠道药物溶解度.
- 这种方法,结合肠道透性,提供了基于人口的改善生物制药评估.
- 该系统增强了药物开发中的预测能力,并可能适用于其他复杂的生物流体.

Methods for Studying Drug Absorption: In vitro
The diffusion cell method uses a two-compartment cell, including a donor compartment with the drug solution, which simulates the environment where the drug is applied, and a receptor compartment with a buffer solution, which simulates the environment...
Methods for Studying Drug Absorption: In situ
The Doluisio method involves perfusing a prepared segment of a rat's small intestine with a solution of radiolabeled drug and a non-absorbable marker. This helps to differentiate between absorbed and non-absorbed drug concentrations. The intestinal segment is connected at both ends using tubing and syringes,...
Theories of Dissolution: Diffusion Layer Model
This process starts with a thin layer, saturated with the drug, forming at the interface between the solid and liquid. The solute then diffuses from this layer into the main solution. The Noyes-Whitney equation suggests that the rate of dissolution relies on the diffusion...
