Current weight\u2010based dosing and anti\u2010Xa monitoring provide limited guidance for dose optimization across burn severities. This study develops a physiologically based pharmacokinetic (PBPK) model of enoxaparin across burn phases to evaluate target attainment under standard dosing while accounting for burn severity, augmented renal clearance (ARC), and body weight, and to propose individualized dosing strategies to improve VTE prophylaxis. Real\u2010world data of 1288 anti\u2010Xa concentrations were collected from 408 burn patients receiving subcutaneous enoxaparin. A PBPK model was developed in healthy adults and extrapolated to burn patients by incorporating burn\u2010specific changes, including reduced absorption and decreased antithrombin levels. This validated PBPK model for burn patients was used to simulate dosing regimens across burn severities and ARC, with model performance assessed using average fold error (AFE) and absolute average fold error (AAFE). Sub\u2010therapeutic drug exposure was most prominent from 0 to 96\u2009h post burn across all severities. In obese patients, dose escalation from 40 to 60\u2009mg reduced subtherapeutic exposure from 27.3% to 16.9%. Although trough anti\u2010Xa concentrations increased with higher doses, levels remained lower in patients with ARC compared to those with normal renal clearance (NRC), indicating the need for dose adjustment in ARC. Standard enoxaparin dosing is frequently inadequate in burn patients, particularly early after injury and in those with ARC. PBPK\u2010informed precision dosing can improve VTE prophylaxis beyond weight\u2010based dosing with anti\u2010Xa monitoring alone.<\/jats:p>","DOI":"10.1002\/psp4.70265","type":"journal-article","created":{"date-parts":[[2026,5,18]],"date-time":"2026-05-18T22:39:14Z","timestamp":1779143954000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Optimizing
