SR Print(0) ID 1179991543 T1 HEPARINS T2 Poisoning & Drug Overdose, 7e YR 2018 FD 2018 PB McGraw-Hill Education PP New York, NY SN 9780071839792 LK accessmedicine.mhmedical.com/content.aspx?aid=1179991543 RD 2024/04/23 AB Heparins (Table II–32) have been used for many years as injectable anticoagulants for prophylaxis of thromboembolic disease and management of multiple conditions including hypercoagulable disorders, venous thromboembolic disease, acute coronary syndrome, and to maintain patency in intravascular access and hemodialysis machines. Conventional or unfractionated heparin (UFH) is primarily administered in health care settings and thus intentional overdoses are rare; most cases involve inadvertent iatrogenic administration errors. Low–molecular-weight-heparins (LMWHs) are obtained from UFH and have greater bioavailability, longer half-life, predictable anticoagulation with a fixed-dose schedule, and are more easily self-administered by patients in outpatient settings.
