Low and Highly Variable Exposure to Prophylactic LMWH Nadroparin in Critically Ill Patients: Back to the Drawing Board for Prophylactic Dosing?

Abstract: Background and Objective Low-molecular-weight heparins are routinely administered to patients in the intensive care unit to prevent venous thromboembolisms. There is considerable evidence that low-molecular-weight heparin doses should be personalised based on anti-Xa levels, but pharmacokinetic data in intensive care unit patients are lacking. This study aimed to characterise the pharmacokinetics and associated variability of the low-molecular-weight heparin nadroparin in critically ill patients. Methods Criti… Show more

“…A population PK model was developed to characterize the relationship between dose and anti-Xa levels in neonates and infants receiving thromboprophylactic treatment with nadroparin at a dose of 150–200 IU/kg q12 h. To our knowledge, only a few previous population PK models of nadroparin have been published, including studies in morbidly obese bariatric surgery patients ( Diepstraten et al, 2015 ), pediatric open heart surgery patients ( Laporte et al, 1999 ), patients receiving hemodialysis ( Jaspers et al, 2022 ), critically ill adult patients ( Diepstraten et al, 2023 ), and COVID-19 intensive care unit patients ( Piwowarczyk et al, 2023 ; Romano et al, 2023 ). However, no population PK analyses have been conducted for nadroparin in neonates and infants.…”
