Abstract :

Pulmonary drug delivery via oral inhalation is increasingly used for both treatment of lung diseases and for delivering drugs to the systemic circulation. Efficacy and safety of orally inhaled drugs is dependent on deposition and absorption of drugs in targeted region. However, due to the complex pharmaceutical and physiological factors involved in drug transfer from the administration site to the target region, it is difficult to experimentally capture the detailed mechanistic insights of involved pulmonary drug delivery processes.
In the present study, we have developed a novel predictive multi scale computational tool to simulate delivery, deposition, dissolution, absorption, distribution, metabolism, excretion, and actions of inhaled drug products within an integral framework of computational fluid dynamics (CFD) and PBPK-PD models. The tools and models will be used in predicting the effects of inhalation devices, drug formulation, compound physiochemical characteristics, physiological settings, and various pathological factors on drug deposition and distribution. Ultimately, we aim to provide not only the detailed mechanistic insights into key aspects affecting efficacy and safety of inhaled drug products, but also to guide optimal designs of pulmonary drug delivery systems, inhaled formulations, to prescribe these therapies optimally. Research reported in this study is supported by the U.S. Food and Drug Administration (FDA) under award number 1U01FD005214-01.
