The aim of this study was to develop and validate a FDC autosampler, Otto, that could be retrofitted to generic FDCs to automate sampling and refilling. Methylene blue (MB) was used as a model drug to assess the volume consistency and accuracy of the samples. Otto achieved highly consistent sample volumes (coefficient of variation, CV = 3.2 %), surpassing the consistency of manual operation (CV = 7.4 %). The amount of MB measured across multiple sampling-refill cycles mirrored the theoretical amount, as well as the amount determined through manual operation. Otto collected up to 100 samples unattended, over 24 h, in an in vitro ibuprofen permeation study. The samples were collected into standard sample vials to integrate seamlessly with downstream analytical equipment. Otto improved the quality of the permeation data over manual sampling, by sampling automatically around the clock to effectively maintain sink condition in the FDC. It therefore offers a cost-effective, performant and reliable automation solution for permeation studies that use the FDC.</div></div>","PeriodicalId":16741,"journal":{"name":"Journal of pharmaceutical sciences","volume":"114 7","pages":"Article 103837"},"PeriodicalIF":3.7,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144078491","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}

While chronomodulated chemotherapy for 5-fluorouracil infusion regimens can improve patient outcomes, the impact of circadian rhythms on oral 5-fluorouracil prodrug regimens remains poorly understood, and no dose-timing strategies have been established. This study investigated circadian variations in the pharmacokinetics of 5-fluorouracil after administering S-1, an oral fluoropyrimidine-based anticancer drug, in rats using a cosinor-based chronopharmacokinetic model. Plasma tegafur exposure showed significant circadian variation, peaking at 01:00 (17 h after light onset), whereas plasma 5-fluorouracil exposure exhibited no significant time-of-dosing differences. Chronopharmacokinetic analysis revealed minimal circadian variation in 5-fluorouracil clearance with S-1 (amplitude-to-mesor ratio: ±14.6 %) compared to long-term 5-fluorouracil infusion (±28.0 %) and other oral prodrugs including capecitabine (±43.0 %) and uracil-tegafur (±36.7 %), which showed pronounced fluctuations. These results suggest that S-1 provides consistent 5-fluorouracil exposure regardless of dosing time, offering a practical advantage by simplifying treatment schedules and reducing the need for chronomodulated therapy.

This study employed a physiologically based pharmacokinetic (PBPK) model to characterize the disposition of tapentadol in children across different age groups and to refine pediatric dosing strategies. Initially, an adult PBPK model was developed using the ‘middle-out’ strategy, which was then adjusted by scaling anatomical and physiological parameters to apply it to pediatric populations. The model's precision was confirmed by comparing the simulated plasma concentrations in a virtual population with empirical data. Utilizing this model, we translated dosages from adults to children and assessed weight-adjusted dosages for children aged 2 to 18 years and those under 2 years. The ratios of predicted to observed pharmacokinetic (PK) parameters for adult tapentadol ranged from 0.80 to 1.40 with the pediatric population's predictive mean absolute prediction error (MAPE) being less than 0.45. Based on model validation, we have established the following fixed-dose regimen for tapentadol oral solution for children across various age groups: 2.5 mg for 0–1 month, 3.5 mg for 1–3 months, 5 mg for 3–6 months, 8.5 mg for 6 months to 1 year, 13 mg for 1–2 years, 20 mg for 2–6 years, 35 mg for 6–12 years, and 60 mg for 12–18 years.
