Semi-solid extrusion (SSE) as a way of 3D printing has shown a substantial potential in personalized medicine for pediatric patients. However, manufacturing tablets through 3D printing is a slow process and might be a bottleneck when many personalized dosages are needed for pediatric use. Here, we use a simplified SSE printing approach for preparing propranolol, spironolactone, and prednisolone tablets (<em>n</em> = 144 of each) with different dosages. The quality control approach for the tablets included the development of HPLC methods for each drug based on their physicochemical properties and investigation of mass and content uniformity, stability, and dissolution. The average dosing accuracy showed good mass uniformity. All the formulations showed an appropriate homogeneity (AV&lt;15) and stability up to 9 months. Dissolution results of the tablets were in compliance with acceptance criteria (USP) for immediate release dosage forms, i.e., 80% of drug released within 45 min. The osmolality of placebo, propranolol, spironolactone, and prednisolone tablets were 86, 81, 78, and 75 mOsm/kg, respectively. These osmolality values were well below the recommended osmolality of pediatric formulations, i.e., &lt; 450 mOsm/kg. Finally, drug recovery tests via nasogastric tube (NGT) were performed with different reconstitution volumes and temperatures. The drug losses varied between 4–36%. The findings of this study suggest that a simplified SSE printing approach is a promising method for manufacturing personalized medicines and can be used to accurately produce tailor-made dosage forms for pediatric patients.</div></div>","PeriodicalId":12018,"journal":{"name":"European Journal of Pharmaceutical Sciences","volume":"211 ","pages":"Article 107122"},"PeriodicalIF":4.3,"publicationDate":"2025-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143971090","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Subsequently, employing a grid search-based technique to discretize the operational variable domain facilitates the exploration of the probabilistic DS to meet the specified product quality requirements.

These benefits include increased flexibility, higher product output, enhanced quality assurance through better monitoring techniques, and more consistent distribution of Active Pharmaceutical Ingredients (APIs).

This study explores the optimisation processes of continuous pharmaceutical production, explicitly targeting the production of mefenamic acid using wet milling (WM) and mixed-suspension mixed-product removal (MSMPR). We employ data-driven evolutionary optimisation algorithms to address these many-objective optimisation problems (MaOPs). High-fidelity model-generated data generated via the General Process Modelling System (gPROMS) is subsequently utilised to develop simpler surrogate models based on the Radial Basis Function Neural Network (RBFNN). This enables very fast simulations, suitable for use with computationally intensive machine learning algorithms. Utilising evolutionary optimisation algorithms, these models are used for model-based process optimisation. The efficacy of the MaOP approach is evaluated using a range of numeric and visual optimisation performance indicators. Our findings underscore the viability of integrating high-fidelity and surrogate models to discern functional relationships between dependent variables (objective functions) and independent variables (decision variables), providing a robust framework for process optimisation within the pharmaceutical domain. The approximated solutions are, on average, 58% better than the solutions obtained from Latin hypercube sampling. The chosen optimal solutions can form the basis of parameter setting in upcoming experimental campaigns.
