Nistrom from Neiss contains Acenocoumarol
Below are some of the details of Acenocoumarol(generic)
Acenocoumarol is an anticoagulant that functions as a vitamin K antagonist (like warfarin). It is a derivative of coumarin and is marketed under the brand names Sintrom and Sinthrome. Anticoagulants decrease the clotting ability of the blood and therefore help to prevent harmful clots from forming in the blood vessels. These medicines are sometimes called blood thinners, although they do not actually thin the blood. They also will not dissolve clots that already have formed, but they may prevent the clots from becoming larger and causing more serious problems. They are often used as treatment for certain blood vessel, heart, and lung conditions. In order for an anticoagulant to help without causing serious bleeding, it must be used properly and all of the precautions concerning its use must be followed exactly.
