The IOT methods have recently demonstrated great potential for monitoring the quality of continuous powder mixtures by near-infrared (NIR) spectroscopy. However, the dynamic conditions of continuous manufacturing processes may limit the effectiveness of such approaches. Density variations introduced to NIR spectra that are collected from dynamic powder mixtures at different process conditions is detrimental to the drug prediction accuracy and robustness of IOT methods. This work introduces a new method, called external variable augmented iterative optimization technology (EVA-IOT), which incorporates the shape of non-chemical external sources of variability into the pure component spectra matrix to improve the prediction accuracy and robustness of the base IOT algorithm. This approach derives the shape of non-chemical external variables from the latent structure of decomposition methods using NIR spectra acquired from a single mixture at known levels of the external variable. A density-augmented EVA-IOT method was developed and implemented to quantify the active pharmaceutical ingredient (API) in continuous powder mixtures flowing at varying process conditions in a simulated continuous process. The EVA-IOT method demonstrated a significantly enhanced API prediction accuracy and robustness against process variation compared to alternative IOT methods. The overall prediction performance of EVA-IOT was comparable to that of global partial least square (PLS) regression models while reducing the calibration burden up to 97%. This makes EVA-IOT a material-sparing alternative to calibration-intensive robust decomposition modeling approaches for monitoring the quality of continuous pharmaceutical powder streams.</div></div>","PeriodicalId":12024,"journal":{"name":"European Journal of Pharmaceutics and Biopharmaceutics","volume":"207 ","pages":"Article 114626"},"PeriodicalIF":4.4,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143002751","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work reports the functionalisation of a commercially available silica microparticle (SYLOID XDP 3050) with stearic acid at various stearic acid loading concentrations (20–120 % w/w). Scanning electron microscopy (SEM) analysis revealed that the pores were capped with stearic acid, with the filling ratio increasing proportionally to the loading concentration. Notably, needle-like structures appeared when the stearic acid amount exceeded 80 % w/w, surpassing the calculated theoretical maximum pore filling ratio (64.32 %). The molecular interactions were highlighted using Fourier-transform infrared spectroscopy (FTIR), as the intensity of the CH<sub>3</sub> increased with increased stearic acid loading concentrations. The needle-structures phenomenon was corroborated by 3D confocal imaging. It utilised the autofluorescence properties of stearic acid to demonstrate its presence within the carrier, with fluorescence intensity increasing alongside the stearic acid concentration. Differential scanning calorimetry (DSC) indicated the crystalline nature of these needle structures, which was further confirmed by X-ray diffraction (XRD) analysis, validating the crystallisation of the stearic acid needles. Moreover, nitrogen porosimetry was employed to assess the pore volume and surface area, where the formulation containing 120 % stearic acid exhibited the lowest pore volume (0.59 cc).

Indeed, failure in the resolution of inflammation leads to serious pathological conditions, such as cardiovascular diseases, arthritis, cancer, diabetes, autoimmune diseases, and neurodegenerative disorders that are often associated with extremely high human suffering and societal and economic burdens. Despite the number and efficacy of available therapeutic agents have been increased, the serious side effects associated with some of them often create a very high risk/benefit ratio for patients. Therefore, herein, a drug delivery system was engineered to overcome important drawbacks of conventional therapies and to have a synergistic action with the incorporated drug. Indeed, it will have an added beneficial role in controlling inflammation. For that, sardine (<em>Sardina pilchardus</em>) roe was used as the lipidic source to produce bioactive liposomes, namely fishroesomes. These spherical vesicles with ≈326 nm in size and a significant negative surface charge (≈-31 mV) were able to encapsulate and control the release of the anti-inflammatory drug celecoxib. Moreover, fishroesomes were cytocompatible for different cell types (chondrocytes and macrophages), at concentrations in which they present anti-inflammatory properties. Importantly, fishroesomes were more effective in reducing pro-inflammatory mediators than the free drug. We also demonstrated that a single intra-articular injection of the fishroesomes encapsulating or not celecoxib in an experimental rat model of inflammatory arthritis was safe and more effective in controlling the pain and reducing the synovial inflammation compared to the free drug. Notably, as the celecoxib concentration in the sardine roe-derived liposomes was less than half of the amount of free drug, this study demonstrates the value of fishroesomes in counteracting inflammation.

Numerous nanotechnology-based formulation approaches have been seen succeeding in commercialization. Despite the progress in nanomedicine use in adults, the advancement in pediatric population has been much slower. Clearly the treatment of disease in children cannot be simplified by dose adjustment based on body weight or surface, due to the significant differences in physiology thus the drug absorption, distribution, metabolism, excretion and transport (ADMET), between children and adults. This inherent variable among others poses much more challenges when developing pediatric-specific nanomedicine or translating adult nanodrug to pediatric indication. This review therefore intends to highlight the physiological differences between children and adult, and the common pediatric diseases which are good candidates for nanomedicine.
