Phenacyl bromide is the organic compound with the formula C 6 H 5 C(O)CH 2 Br. This colourless solid is a powerful lachrymator as well as a useful precursor to other organic compounds. It is prepared by bromination of acetophenone: [2] C 6 H 5 C(O)CH 3 + Br 2 → C 6 H 5 C(O)CH 2 Br + HBr. The compound was first reported in 1871. [3]
Native heparin is a polymer with a molecular weight ranging from 3 to 30 kDa, although the average molecular weight of most commercial heparin preparations is in the range of 12 to 15 kDa. [60] Heparin is a member of the glycosaminoglycan family of carbohydrates (which includes the closely related molecule heparan sulfate ) and consists of a ...
A common low molecular weight heparin drug is called enoxaparin (brand name Lovenox). Enoxaparin is listed as Pregnancy Category B, meaning animal studies have failed to show harmful effects to the fetus and therefore are safe to use in pregnant women.
Rather, women who are on chronic anticoagulation may be given the option of conversion to either unfractionated heparin or low molecular weight heparin (LMWH), such as tinzaparin, [13] prior to a planned conception. [17] LMWH is as safe and efficacious as unfractionated heparin. [13]
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]
Low-molecular-weight heparin (LMWH) is a class of anticoagulant medications. [1] They are used in the prevention of blood clots and, in the treatment of venous thromboembolism ( deep vein thrombosis and pulmonary embolism ), and the treatment of myocardial infarction .
Low molecular weight heparin (LMWH, such as enoxaparin) is generally used as an alternative. [44] Warfarin and LMWH may safely be used in breastfeeding. [44] When women experience recurrent pregnancy loss secondary to thrombophilia, some studies have suggested that low molecular weight heparin reduces the risk of miscarriage.
A combination of pregnancy-exacerbated hypercoagulability and additional risk factors such as obesity and thrombophilias makes pregnant women vulnerable to thrombotic events [29] T.he prophylactic measures that include the usage of low molecular weight heparin, in fact, can significantly reduce risks associated with surgery, particularly in ...
