  2. Heparin - Wikipedia

    en.wikipedia.org/wiki/Heparin

    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 ...

  3. Low-molecular-weight heparin - Wikipedia

    en.wikipedia.org/wiki/Low-molecular-weight_heparin

    Average molecular weight: heparin is about 15 kDa, and LMWH is about 4.5 kDa. [25] Less frequent subcutaneous dosing than for heparin for postoperative prophylaxis of venous thromboembolism. Once or twice daily subcutaneous injection for treatment of venous thromboembolism and in unstable angina instead of intravenous infusion of high-dose heparin.

  4. Tinzaparin sodium - Wikipedia

    en.wikipedia.org/wiki/Tinzaparin_sodium

    Tinzaparin is an antithrombotic drug in the heparin group. It is a low molecular weight heparin (LMWH) marketed as Innohep worldwide. It has been approved by the U.S. Food and Drug Administration (FDA) for once daily treatment and prophylaxis of deep vein thrombosis (DVT) and pulmonary embolism (PE).

  5. Thrombosis prevention - Wikipedia

    en.wikipedia.org/wiki/Thrombosis_prevention

    A 2021 review found that low molecular weight heparin (LMWH) was superior to unfractionated heparin in the initial treatment of venous thromboembolism for people with cancer. [3] There are medication-based interventions and non-medication-based interventions. [4]

  6. Venous thrombosis - Wikipedia

    en.wikipedia.org/wiki/Venous_thrombosis

    Traditionally this was heparin, but several of the DOACs are licensed for treatment without initial heparin use. [42] If heparin is used for initial treatment of VTE, fixed doses with low-molecular-weight heparin (LMWH) may be more effective than adjusted doses of unfractionated heparin (UFH) in reducing blood clots. [44]

  7. Protamine sulfate - Wikipedia

    en.wikipedia.org/wiki/Protamine_sulfate

    Protamine sulfate is a medication that is used to reverse the effects of heparin. [3] It is specifically used in heparin overdose, in low molecular weight heparin overdose, and to reverse the effects of heparin during delivery and heart surgery. [3] [4] It is given by injection into a vein. [3] The onset of effects is typically within five ...

  8. Hypercoagulability in pregnancy - Wikipedia

    en.wikipedia.org/wiki/Hypercoagulability_in...

    Still, LMWHs are much less likely to cause heparin-induced thrombocytopenia than unfractionated heparin. [13] Regional anaesthesia is contraindicated in women on therapeutic anticoagulation, and should not be used within 24 hours of the last dose of tinzaparin. [13]

  9. Clotting time - Wikipedia

    en.wikipedia.org/wiki/Clotting_time

    Internationalized normalized ratio (INR) is also a warfarin study, with therapeutic ranges of 2–3 for standard warfarin and 3–4.5 for high-dose warfarin. [6] In a veterinary study of bovine animals, the mean ACT was 145 seconds with a range of 120–180 seconds. Standard deviations were 18 and 13 for the first and second sampling, respectively.
