需要翻译药代动力学(PK)模型来描述和预测作用部位肺组织中的药物浓度-时间分布,以实现动物到人的翻译和对吸入性药物在人体内的疗效的预测。目前的肺PK模型一般是描述性的,而不是预测性的,具有药物/化合物特异性,并且不能显示成功的跨物种翻译。这项工作的目的是开发一种健壮的间隔模拟方法,该方法捕捉肺给药后肺和全身PK的关键特征,该组12种可溶性药物包含单一碱性、二碱性或阳离子官能团。该模型被证明允许在动物种类之间进行转换,并预测人类肺部的药物浓度与不同类别的支气管扩张剂的用力呼气量相关。因此,肺模型方法有可能成为预测人类PK、疗效和未来吸入药物安全性的关键组成部分。
Translational pharmacokinetic (PK) models are needed to describe and predict drug concentration‐time profiles in lung tissue at the site of action to enable animal‐to‐man translation and prediction of efficacy in humans for inhaled medicines. Current pulmonary PK models are generally descriptive rather than predictive, drug/compound specific, and fail to show successful cross‐species translation. The objective of this work was to develop a robust compartmental modeling approach that captures key features of lung and systemic PK after pulmonary administration of a set of 12 soluble drugs containing single basic, dibasic, or cationic functional groups. The model is shown to allow translation between animal species and predicts drug concentrations in human lungs that correlate with the forced expiratory volume for different classes of bronchodilators. Thus, the pulmonary modeling approach has potential to be a key component in the prediction of human PK, efficacy, and safety for future inhaled medicines.
