Special Issue Information

Dear Colleagues,

Physiologically-Based Pharmacokinetics (PBPK) modeling represents advancements in mathematical models based on information from animal and human physiology that can be integrated with the physicochemical information of a drug to predict its concentration in any tissue. Physiologically-Based Biopharmaceutics (PBBM) modeling establishes a link between the performance of a formulation, such as in vitro drug dissolution, and a PBPK model. In this context, PBPK and PBBM approaches are of great interest to pharmaceutical companies for various applications, particularly in the development of formulations with desirable drug release, the evaluation of the bio-predictive and clinical relevance of dissolution methods, support for formulation changes, assessment of the impact on bioequivalence (BE) due to any formulation modifications, and to run virtual BE studies. PBPK and PBBM can also be employed for predicting drug disposition from other routes of administration, such as injectable, nasal–pulmonary, dermal, transdermal, ocular, and buccal.

This Special Issue aims to gather recent advances in the use of PBBK and PBBM for formulation development, encompassing all aspects that can contribute to supporting drug product development. We are pleased to invite you to submit original research articles or reviews utilizing PBPK and/or PBBM for drug product development (across all dosage forms). Topics of interest may include, but are not limited to, biopharmaceutics applications, the evaluation of dissolution methods, regulatory applications, post-approval changes, virtual bioequivalence studies, and in vitro–in vivo correlation.

We look forward to receiving your contributions.

Background: Combination medication strategies often involve complex interactions, making determining the appropriate pharmacodynamic component ratios challenging. Methods: This study established a time–dose relationship model through the compartment model, deriving the in vivo drug quantity ratios corresponding to the blood concentrations of the pharmacodynamic components. A neural network was then employed to establish a dose–effect relationship model between the blood concentrations of the pharmacodynamic components and the overall body response. Utilizing the feedback adjustment mechanism of neural networks continuously adjusts the network to achieve the desired drug efficacy, thereby deriving the corresponding dose ratio of the pharmacodynamic components. Empirical studies were conducted on combining Cynanchum otophyllum saponins M1 and M2 with phenobarbital for epilepsy treatment, as well as the anti-ischemic stroke activity of the prototype and metabolites of Erigeron breviscapus. Results: After adjusting the efficacy, the model recalculated the new ratio proportions for each combination, validated by the reduced Combination Index (CI). Conclusions: This model provides a new approach to combination medication strategies. Full article

Long-acting injectable (LAI) formulations provide sustained drug release over an extended period ranging from weeks to several months to improve efficacy, safety, and compliance. Nevertheless, many challenges arise in the development and regulatory assessment of LAI drug products due to a limited understanding of the tissue response to injected particles (e.g., inflammation) impacting in vivo performance. Mechanism-based in silico methods may support the understanding of LAI–physiology interactions. The objectives of this study were as follows: (1) to use a mechanistic modeling approach to delineate the in vivo performance of DepoSubQ Provera® and formulation variants in preclinical species; (2) to predict human exposure based on the knowledge gained from the animal model. The PBPK model evaluated different elements involved in LAI administration and showed that (1) the effective in vivo particle size is potentially larger than the measured in vitro particle size, which could be due to particle aggregation at the injection site, and (2) local inflammation is a key process at the injection site that results in a transient increase in depot volume. This work highlights how a mechanistic modeling approach can identify critical physiological events and product attributes that may affect the in vivo performance of LAIs. Full article
