Solid pharmaceutical formulations with class II active pharmaceutical ingredients (APIs) face dissolution challenges due to limited solubility, affecting in vivo behavior. Robust computational tools, via data mining, offer valuable insights into product performance, complementing traditional methods and aiding in scale-up decisions. This study utilizes the design of experiments (DoE) to understand fluidized hot-melt granulation manufacturing technology. Exploratory data analysis (MVDA) highlights similarities and differences in tablet manufacturability and dissolution profiles at both the lab and pilot scales. The study sought to gain insights into the application of multivariate data analysis by identifying variations among batches produced at different manufacturing scales for this technology. DoE and MVDA findings show that the granulation temperature, time, and Macrogol type significantly impact product performance. These factors, by influencing particle size distribution, become key predictors of product quality attributes such as resistance to crushing, disintegration time, and early-stage API dissolution in the profile. Software-aided data mining, with its multivariate and versatile nature, complements the empirical approach, which is reliant on trial and error during product scale-up.

Background/Objectives: Non-communicable diseases (NCDs) are the leading cause of preventable morbidity and mortality globally. To reduce the prevalence of NCDs, the World Health Organization issued guidelines for a healthy lifestyle, which have been adopted in various countries. Our study aimed to evaluate the dietary habits of the ethnic Hungarian population of Romania, allowing us to identify potential differences in nutritional behavior compared to the country’s general population. Methods: A cross-sectional, observational, questionnaire-based study was conducted to collect information on eating behavior, food purchasing habits, and dietary patterns among ethnic Hungarians, the largest minority group in Romania. The obtained data were interpreted using multivariate data analysis (MVDA), including principal component analysis models (PCA-X) to establish pattern recognition and data clustering, and orthogonal partial least squares discriminant analysis (OPLS-DA) models to examine class differences between the identified clusters. Results: A total of 247 valid questionnaires were evaluated; the most represented groups were females (67.2%), young adults aged 18 to 30 (56.3%), individuals with normal body mass index (54.7%), and those with a higher education level (45.7%). Health-conscious purchasing and eating behaviors were more characteristic of middle-aged and older adults, females, and those with a higher education level. Young adults appear to have a more varied diet, but overconsumption of unhealthy food products and a lack of interest in healthy dietary habits is evident. Conclusions: Appropriate nutritional education is necessary for all age groups; however, programs targeting young adult Hungarians are especially important, as most expressed little interest in healthy eating habits. Further research examining the underlying relationship between dietary habits and cultural factors as well as socio-economic factors could offer new opportunities to promote a healthy lifestyle.

Background: The widespread availability of over-the-counter (OTC) medicines supports self-care but also requires users to recognize medication-related risks and make safe decisions without direct professional supervision. Existing studies have often examined medication literacy, self-medication, or pharmacovigilance separately. To address this gap, we developed a questionnaire within the conceptual framework of OTC medication risk literacy to explore scenario-based OTC medicine risk recognition, self-assessed confidence, self-reported safety behaviours, information-seeking practices, and pharmacovigilance awareness among respondents recruited through an online survey in Romania. Methods: A cross-sectional observational study was conducted using an anonymous Google Forms questionnaire. Data were collected between June–July 2026. The questionnaire included scenario-based items addressing common OTC medicine risks, self-assessed confidence in medication-related decision-making, self-reported safety behaviours, information sources, chronic disease and medicine use, adverse effect experience, reporting behaviour, and pharmacovigilance awareness. Associations were evaluated using chi-square tests, effect-size measures, and multivariable regression analyses. Results: A total of 423 respondents completed the survey. Recognition of major medication-safety risks was high for persistent symptoms requiring medical evaluation (96.5%), severe allergic reactions (95.7%), severe cutaneous adverse effects (96.2%), OTC medicine use during pregnancy (95.7%), antibiotic misuse (89.8%), and contraindications associated with chronic disease or anticoagulant therapy (91.7–92.7%). In contrast, recognition was lower for the antihistamine–alcohol interaction scenario, for which only 53.9% selected the safest response. Confidence was highest for understanding information provided on medicine packaging and patient information leaflets, whereas lower confidence was reported for recognising unsafe medicine combinations and contraindications. Most respondents reported reading medicine packaging and following recommended dosage instructions. Doctors (69.0%), pharmacists (61.2%), and patient information leaflets (56.3%) were the most used information sources. Pharmacovigilance awareness was limited, although 45.1% of respondents agreed that they knew how to report a suspected adverse effect, 35.0% disagreed and 52.3% of eligible respondents reported having previously submitted a suspected adverse effect report. Healthcare background remained independently associated with higher recognition and confidence scores after adjustment. Conclusions: In this online convenience sample, respondents generally recognized major OTC medicine safety risks in structured scenarios and reported several safe-use behaviours, but practical gaps remained in interaction recognition, complex risk assessment, and pharmacovigilance awareness. The findings should be interpreted as exploratory and not as representative national estimates. Scenario-based assessment may help identify educational priorities, while pharmacist counselling, clearer information, and pharmacovigilance education remain plausible strategies that require further evaluation.
