Phytomenadione, also known as vitamin K 1 or phylloquinone, is a vitamin found in food and used as a dietary supplement. [6] [7] It is on the World Health Organization's List of Essential Medicines. [8] It is used to treat certain bleeding disorders, [7] including warfarin overdose, vitamin K deficiency, and obstructive jaundice. [7]
Warfarin is indicated for the prophylaxis and treatment of venous thrombosis and its extension, pulmonary embolism; [9] prophylaxis and treatment of thromboembolic complications associated with atrial fibrillation and/or cardiac valve replacement; [9] and reduction in the risk of death, recurrent myocardial infarction, and thromboembolic events such as stroke or systemic embolization after ...
Phenprocoumon is an inhibitor of the enzyme vitamin K epoxide reductase (VKOR). Vitamin K is needed to activate the coagulation factors II, VII, IX and X [9] and the anticoagulation factors protein C and protein S, [10] in which process it turns into vitamin K 2,3-epoxide. This is then recycled to vitamin K in a process involving VKOR.
Vitamin K is a family of structurally similar, fat-soluble vitamers found in foods and marketed as dietary supplements. [1] The human body requires vitamin K for post-synthesis modification of certain proteins that are required for blood coagulation ("K" from Danish koagulation, for "coagulation") or for controlling binding of calcium in bones and other tissues. [2]
The term "vitamin K antagonist" is a misnomer, as the drugs do not directly antagonise the action of vitamin K in the pharmacological sense, but rather the recycling of vitamin K. Vitamin K is required for the proper production of certain proteins involved in the blood clotting process.
One cup of beet greens has 12% of the daily value of vitamin C and more than 100% of your daily vitamin K. In other words, they are good for the immune system , blood clotting and bone health ...
The normal range for a healthy person not using warfarin is 0.8–1.2, and for people on warfarin therapy an INR of 2.0–3.0 is usually targeted, although the target INR may be higher in particular situations, such as for those with a mechanical heart valve. If the INR is outside the target range, a high INR indicates a higher risk of bleeding ...
Superwarfarins are highly potent vitamin K antagonist anticoagulants that are used as rodenticides. They are called superwarfarins because they are much more potent and long acting than warfarin . [ 1 ]
