However, it is a poorly water-soluble molecule, leading to low and variable oral bioavailability. This study investigated hot-melt extrusion (HME), spray drying, and KinetiSol processing (KSD) using Soluplus (SOL) to enhance FBZ’s solubility. Formulating FBZ as an amorphous solid dispersion (ASD) by HME at a barrel temperature of 120 °C led to extensive chemical degradation of FBZ, generating the degradation product fenbendazoleamine. On the other hand, spray-drying (SD) generated an ASD, but its usefulness was greatly limited by the low solubility of FBZ in the cosolvent system required in the SD process. Given FBZ’s poor solubility in both water and organic solvents and its thermolabile propensity, KSD was explored. Conventional KSD parameters reduced the impurity levels to 6.4 % at a discharge temperature of 64 °C. To further minimize impurity levels, we investigated alternative KSD parameters that terminate the process before reaching the melt agglomeration phase. These conditions resulted in powder-discharged KSD samples (pKSD) that avoided causing chemical degradation of FBZ. The pKSD samples exhibited trace crystallinity, as confirmed by Wide Angle X-ray Scattering (WAXS). Scanning electron microscopy (SEM) revealed that these samples comprised nano- and micron-sized particle aggregates. These results were confirmed by processing FBZ with other excipients, such as semi-crystalline polymers and cyclodextrins. The pKSD samples demonstrated improved dissolution performance of FBZ compared to the physical mixture and crystalline neat FBZ due to the smaller particle size of FBZ. pKSD FBZ provides a solution for formulating thermolabile molecules like FBZ while only requiring a few seconds of exposure to the pKSD manufacturing process conditions, thus eliminating the disadvantages of SD (e.g., requiring sufficiently high solubility in the organic solvent system) and HME (e.g., exposure to high shear and heat during the process).</div></div>","PeriodicalId":14187,"journal":{"name":"International Journal of Pharmaceutics","volume":"676 ","pages":"Article 125582"},"PeriodicalIF":5.3,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143842983","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}

However, while SeNPs and PDA have demonstrated efficacy in several disease models, their role in OA remains underexplored. This study aimed to evaluate the therapeutic effects of PDA-coated SeNPs in the treatment of OA. We developed PDA-coated SeNPs (PDA-SeNP) to improve Reactive Oxygen Species (ROS) control and evaluated their anti-inflammatory and cartilage-regenerative effects in both <em>in vitro</em> and <em>in vivo</em> models of OA. Transmission electron microscopy confirmed that the sizes of PDA-SeNPs was 203 ± 11 nm, with PDA coatings of approximately 12 ± 2 nm on the SeNPs. <em>In vitro,</em> treatment with PDA-SeNPs significantly enhanced the expression of cartilage-regeneration markers while reducing inflammatory marker levels in chondrocytes. For the <em>in vivo</em> analysis, OA was induced by injecting monoiodoacetate into the knee joints of rats. Four weeks after treatment with phosphate-buffered saline (PBS, n = 6), SeNPs (n = 6), or PDA-SeNPs (n = 6), the incapacitance test demonstrated improved weight-bearing capacity in the SeNP and PDA-SeNP groups compared to the PBS control. Gross morphological assessment and histological analysis revealed that PDA-SeNPs mitigated cartilage damage more effectively than SeNPs alone.
