Processed excipient composites, such as lactose-starch-povidone (LSP) and lactose-starch-povidone-sodium starch glycolate (LSPS), were prepared via a coprocessing strategy and evaluated for their ability to perform specific functions. At predetermined combination levels, aqueous dispersions of primary excipients were physically agglomerated at a controlled temperature below the gelatinization temperature (55 °C) before drying at 60 °C for 48 h. GA-SD and co-processed excipients (LSP and LSPS) were utilized to produce tablet batches GAC1 to GAC8 (Gliclazide-Aerosil 380–co-processed excipients, GAC) by direct compression. Through rigorous testing of tablet batches, the physicochemical properties of the resulting formulations were analyzed and compared to those of leading marketed formulations (MFs). FTIR studies were also conducted to detect drug-excipient interactions in the tablet formulations. The release mechanism of the GLC was determined by studying the dissolution process with various kinetic models. The GAC tablets were subjected to 40 °C/75% RH for 3 months to assess stability.</p><h3>Results</h3><p>All tablet formulations of GA-SD containing co-processed excipients met the weight, friability, disintegration time, mechanical strength, and homogeneity requirements. There was significantly more GLC released from the GAC formulations (<i>p</i> < 0.05) at each time point when the formulations were exposed to water than when the formulations were exposed to MFs. In vitro, testing revealed that the GAC5 to GAC8 formulations were the most efficient due to the presence of the superdisintegrant in the LSPS composite, which may be a contributing factor to the improvement in the dissolution rate by GA-SD. FTIR analysis revealed no notable chemical interactions between GLC and the excipients in the solid state. The Korsmeyer-Peppas model was the best-fit kinetic model, indicating that diffusion is the predominant mechanism of GLC dissolution. According to the commercial standards, the GAC tablets maintained an acceptable hardness, disintegration time, and drug content during the stability studies. Additionally, no significant changes in release profiles were observed in the selected batches (<i>p</i> < 0.05).</p><h3>Conclusion</h3><p>Compared with currently marketed formulations (MFs), GA-SD tablet formulations with co-processed excipients significantly improved the physicochemical properties, including the drug release rate.

To better understand this phenomenon, there is a need for particle detection devices that cannot only distinguish between protein particles and silicone oil droplets but also determine particle sizes ranging from nanometers to micrometers.</p><h3>Method</h3><p>In this study, we conducted a systematic assessment of imaging flow cytometry (IFC) using the FlowSight® instrument. Our first step was to investigate specific instrument settings using protein particle samples spiked with silicone oil for particle classification. Based on these findings, we established suitable, harmonized working templates. Next, we evaluated the instrument’s accuracy and precision for particle sizes within the range of 0.5 to 100 µm and their respective concentrations. Finally, we investigated any constraints in particle concentration within this size range.</p><h3>Results</h3><p>This study demonstrates that IFC can effectively distinguish protein particles from silicone oil droplets when the latter is labeled with a specific fluorescent dye. Our findings suggest that fluorescently labeled particles ≥ 0.5 µm can be reliably detected. Through our research, we determined the particle concentration limits for each particle size in the range of 0.5 to 10 µm, with a precision deviation of less than 15%. However, our study also revealed that IFC exhibited insufficient accuracy for the tested particle concentrations within this size range. Additionally, we showed that the measurements were significantly influenced by the instrument settings.</p><h3>Conclusion</h3><p>Although we addressed numerous new aspects to enhance the experimental procedure of IFC measurements, we conclude that IFC is not an ideal technique for quantifying sub-visible particles. Instead, it should be employed to provide supportive characterization data in conjunction with commonly used sub-visible particle detection methods. If distinguishing between protein particles and silicone oil droplets is essential, IFC is an option, as long as the fluorescent dye is carefully selected.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":656,"journal":{"name":"Journal of Pharmaceutical Innovation","volume":"19 2","pages":""},"PeriodicalIF":2.7,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140008440","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
