Optimizing drug dosing requires a precise understanding of its pharmacokinetics. While it is known that sufentanil concentrations in the blood decline more slowly after epidural administration compared with intravenous administration, and the flip-flop phenomenon has been observed in this context, a pharmacokinetic model accounting for this phenomenon has not yet been described.</p><p><strong>Methods: </strong>This study aimed to develop a pharmacokinetic model of sufentanil following epidural administration, with a focus on its absorption from the epidural space. The study was performed in 23 patients, aged 30-83 years with an American Society of Anesthesiologists (ASA) classification of 2-3, undergoing major abdominal (oncologic and non-oncologic) surgery under general anesthesia and epidural analgesia. Blood samples were collected, and sufentanil concentrations were measured at time points ensuring coverage of the absorption phase. Population analysis was performed using a full Bayesian approach implemented in Stan/Torsten programs with the \"cmdstanr\" and \"bbr.bayes\" packages in RStudio.</p><p><strong>Results: </strong>The Bayesian approach helped incorporate prior information about sufentanil disposition. A two-compartment disposition model with two-compartmental absorption best described the data, featuring a fast absorption rate constant into plasma and the peripheral compartment, and a slow redistribution process from the epidural fat compartment.</p><p><strong>Conclusions: </strong>This study mechanistically describes the flip-flop pharmacokinetics of sufentanil and allows for more precise dosing of epidural sufentanil (NCT06069219).</p>","PeriodicalId":10405,"journal":{"name":"Clinical Pharmacokinetics","volume":" ","pages":"1331-1340"},"PeriodicalIF":4.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12414025/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144526694","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
