模型知情配方开发 (MIFD) 使用生理学基础的药理动力学 (PBPK) 建模来创建持续释放的氧配方. 这种方法成功地降低了度的峰值,并通过生物等价性研究证实了有效性.
科学领域:
- 药理动力学和药物输送方法
- 在制药科学中的计算建模.
背景情况:
- 模型信息化配方开发 (MIFD) 集成了基于生理学的药理动力学 (PBPK) 建模和in silico工具,以高效地开发新产品.
- 氧是一种抗组胺剂,具有显著的镇静副作用,需要优化药物输送以管理其治疗特性.
研究的目的:
- 使用MIFD开发Hydroxyzine的持续释放配方,以降低高峰血度并最大限度地降低镇静作用.
- 通过体内生物等价性研究和in silico预测来验证开发的配方的性能.
- 建立临床相关的溶解规格,并评估基产品的食物效应.
主要方法:
- 使用立即释放的氧数据开发初步的PBPK吸收模型.
- 在各种假设溶解配置的in silico评估以指导配方设计.
- 使用MatrixealTM技术制造持续释放配方.
- 在人类志愿者中进行初步和确认生物等价性 (BE) 研究.
- 根据生物等价性研究结果,改进了PBPK模型.
主要成果:
- 成功开发了一种持续释放的Hydroxyzine配方,证明了血峰值度的降低.
- 虚拟BE研究准确地预测了修改后的配方的性能.
- 在禁食条件下对70名志愿者进行的证实性BE研究验证了新的配方.
- 建立了临床相关的溶解规格,并评估了食物的影响.
结论:
- PBPK建模是开发修饰释放药物产品的宝贵工具,正如Hydroxyzine持续释放配方所证明的那样.
- 通过预测体内性能和指导配方优化,MIFD可以实现高效的产品开发.
- 开发的Hydroxyzine配方提供了潜在的改善治疗特征,降低了镇静作用.
