活性药物成分 (API) 在肠道中的超和行为会影响口服吸收. 将其集成到完善的可开发性分类系统 (rDCS) 中,有助于为更好的生物可用性选择配方.
科学领域:
- 药品制造 药品制造 药品制造
- 生物制药科学 生物制药科学
- 药物运输 药物运输 药物运输
背景情况:
- 活性药物成分 (API) 的口服吸收受到其在胃肠道内的超和沉行为的显著影响.
- 弱基的API可以在肠道转移时通过超和增强吸收,而弱酸的盐形式可以在胃和肠道中实现这一点.
- 具有有限可溶性的API通常需要使配方产生超和溶液以改善肠道吸收.

- 重新审视和完善可开发性分类系统 (rDCS) 以更全面地评估药物可开发性风险.
- 将API的体外超和和沉特征纳入生物制药风险分类框架.
- 通过考虑API的物理化学性质,指导配方选择策略,以优化口服生物可用性 (BA).
主要方法:
- 修改现有的精细的可开发性分类系统 (rDCS) 战略.
- 建议基于API的可开发性对API进行分类的分层方法.
- 整合关于API及其配方的过和沉行为的体外数据.
主要成果:
- 该研究提出了通过结合体外超和沉数据来改进rDCS的方法.
- 这种整合允许更准确地绘制与API相关的潜在可开发性风险.
- 提出的分层方法有助于选择适当的配方,以提高口服吸收.
结论:
- 将体外超和和沉行为集成到rDCS中,为开发能力评估提供了一个强大的策略.
- 这种方法可以更好地预测口服吸收,并指导可溶性有限的API的配方开发.
- 精制的rDCS有助于优化配方选择,以提高口服生物可用性.
