Parallel drug characterization and quality control (QC) in modern dissolution testing rely on real-time measurements. The development of a real-time monitoring platform, including a microfluidic system, a novel eye movement platform featuring temperature sensors, accelerometers, and a concentration probe, in conjunction with an in vitro human eye model (PK-Eye) is detailed. The significance of surface membrane permeability in PK-Eye modeling was determined through the use of a pursing model, a simplified version of the hyaloid membrane. Employing a single pressure source, parallel PK-Eye models were microfluidically controlled in a 16:1 ratio, highlighting the reproducibility and scalability of pressure-flow measurements. The models' intraocular pressure (IOP) was within a physiological range thanks to the pore size and exposed surface area mimicking those of the real eye, underscoring the importance of accurately replicating in vitro dimensions. The program developed to track aqueous humor flow rate highlighted a demonstrable circadian rhythm pattern. Different eye movement capabilities were engineered and attained using a custom-built eye movement platform. Constant release profiles were observed for the injected albumin-conjugated Alexa Fluor 488 (Alexa albumin), as determined by the real-time concentration monitoring provided by the concentration probe. The capacity for real-time monitoring of a pharmaceutical model for preclinical ocular formulations is substantiated by these results.

Collagen's role as a functional biomaterial in directing tissue regeneration and drug delivery is profound, influencing cell proliferation, differentiation, migration, intercellular communication, tissue formation, and the intricate process of blood coagulation. Even so, the traditional procedure of animal collagen extraction could lead to immunogenicity and require intricate material handling and purification steps. While investigating semi-synthetic strategies such as the employment of recombinant E. coli or yeast expression platforms, the presence of unwanted byproducts, the interference of foreign substances, and the imperfections within the synthetic processes have restrained its industrial applicability and clinical deployment. Currently, macromolecular collagen products encounter a significant roadblock in absorption and delivery through standard oral and injection routes, thus inspiring exploration into transdermal, topical, and implantable delivery techniques. This review presents a holistic view of collagen's physiological and therapeutic effects, synthesis techniques, and delivery methods, aiming to inspire and guide future research and development in collagen's applications as a biodrug and biomaterial.

The possible benefits of Elexacaftor/tezacaftor/ivacaftor (ETI) treatment in lung transplant recipients include improvements in conditions beyond the lungs, such as gastrointestinal and sinus issues. However, ivacaftor's role as an inhibitor of cytochrome P450 3A (CYP3A) may lead to concerningly elevated tacrolimus levels in the system. The objective of this study is to evaluate the impact of ETI on tacrolimus pharmacokinetics and formulate a safe and effective dosing regimen to manage the risk of this drug-drug interaction (DDI). A physiologically-based pharmacokinetic (PBPK) model was developed to investigate the CYP3A-driven drug-drug interaction (DDI) between ivacaftor and tacrolimus. The model parameters included ivacaftor's ability to inhibit CYP3A4 and in vitro kinetic data for tacrolimus. To further support the outcomes of the PBPK modeling, we detail a case series of lung transplant patients who were co-treated with both ETI and tacrolimus. Our model predicted a 236-fold elevation in tacrolimus exposure when co-administered with ivacaftor. This necessitates a 50% reduction in tacrolimus dosage upon initiating ETI treatment to prevent the risk of high systemic levels. Thirteen clinical instances revealed a median increase of 32% (interquartile range -1430 to 6380) in the dose-normalized tacrolimus trough level (trough concentration per weight-adjusted daily dose) after the introduction of ETI. These results highlight the possibility of a clinically significant drug interaction between tacrolimus and ETI, thus emphasizing the need for dose adjustments of tacrolimus.
