The
indirect parenteral anticoagulants
in current use include heparin, low-molecular-weight-heparins (LMWHs), fondaparinux, and danaparoid.
What are the types of anticoagulant?
- heparin.
- warfarin (Coumadin)
- rivaroxaban (Xarelto)
- dabigatran (Pradaxa)
- apixaban (Eliquis)
- edoxaban (Savaysa)
- enoxaparin (Lovenox)
- fondaparinux (Arixtra)
What type of anticoagulant is heparin?
Heparins. The heparins are a group
of anticoagulants
that consist of unfractionated heparin, low molecular weight heparins, and heparinoids.
What class of anticoagulant is warfarin?
Vitamin K
Antagonist Anticoagulants
Vitamin K “antagonists” like warfarin stop your liver from processing vitamin K into “factors” that normally help clot your blood. This curbs blood clotting.
What category is heparin in?
Heparin is also used in small amounts to prevent blood clots from forming in catheters (small plastic tubes through which medication can be administered or blood drawn) that are left in veins over a period of time. Heparin is in a class of medications called
anticoagulants (‘blood thinners’)
.
What is the best anticoagulant for blood?
The most commonly prescribed anticoagulant is
warfarin
. Newer types of anticoagulants are also available and are becoming increasingly common.

What is indirect anticoagulant?
Indirect Anticoagulants
Heparins
(glycosaminoglycans) are only administered parenterally. Their mechanism of action is based on the increase in activity of endogenous antithrombin. The anticoagulant effect is therefore dependent of the patient’s antithrombin.
What is the difference between direct and indirect anticoagulants?
Direct FXa inhibitors may
directly bind to FXa
, whereas indirect inhibitors are dependent on antithrombin. Direct inhibitors may bind free FXa and, in contrast to indirect inhibitors, FXa within the prothrombinase complex or within clots as well.
What is the difference between low molecular weight heparin and heparin?
Standard heparin is known to cause adverse reactions called immunogenic responses, such as Heparin Induced Thrombocytopenia (HIT). LMWH is made from standard heparin but is associated with a
lower rate of HIT
than standard heparin.
Why heparin is used as an anticoagulant?
Heparin is a naturally occurring anticoagulant that
prevents the formation and extension of blood clots
. Heparin does not break down clots that have already formed (unlike tissue plasminogen activator) but allows fibrinolysis to work normally to break down clots.
What’s the difference between antiplatelet and anticoagulant?
Anticoagulants such as heparin or warfarin (also called Coumadin)
slow down your body’s process of making clots
. Antiplatelet drugs, such as aspirin, prevent blood cells called platelets from clumping together to form a clot.
What is an example of anticoagulant?
Anticoagulant drugs are used to reduce the ability of the blood to clot. Examples of anticoagulants include
aspirin, heparin and warfarin
.
When should heparin not be given?
You should not use heparin if you have
uncontrolled bleeding
or a severe lack of platelets in your blood. Do not use this medicine if you have ever been diagnosed with “heparin-induced thrombocytopenia,” or low platelets caused by heparin or pentosan polysulfate.
What are the contraindications of heparin?
Contraindications and precautions
Absolute contraindications to heparin include known
hypersensitivity, past or present heparin-induced thrombocytopenia and active bleeding
. Caution is required when prescribing heparin to patients with conditions that may increase the risk of bleeding (see box).
How long does heparin stay in your system?
Although the metabolism of heparin is complex, it may, for the purpose of choosing a protamine dose, be assumed to have a half-life of
about 1/2 hour
after intravenous injection.
