Unfractionated heparin has a half-life of about one to two hours after infusion, [56] whereas low-molecular-weight heparin's half-life is about four times longer. Lower doses of heparin have a much shorter half-life than larger ones. Heparin binding to macrophage cells is internalized and
LMWHs depend more on renal function for their excretion than unfractionated heparin, so their biological half-life may be prolonged in patients with kidney failure. Therefore, their use in patients with creatinine clearance rate ( CrCl ) <30 mL/min may need to be avoided. [ 12 ]
Dalteparin is not superior to unfractionated heparin in preventing blood clots. [5] Heparins are cleared by the kidneys, but studies have shown that dalteparin does not accumulate even if kidney function is reduced. [6] Approximately 70% of dalteparin is excreted through kidneys based on animal studies. [7]
Heparin is the most widely used intravenous clinical anticoagulant worldwide. [82] Heparin is a naturally occurring glycosaminoglycan. There are three major categories of heparin: unfractionated heparin (UFH), low molecular weight heparin (LMWH), and ultra-low-molecular weight heparin (ULMWH). [83]
Enoxaparin is in the low molecular weight heparin family of medications. [11] Enoxaparin was first made in 1981 and approved for medical use in 1993. [12] [11] It is on the World Health Organization's List of Essential Medicines. [13] Enoxaparin is sold under several brand names and is available as a generic medication. [11]
