Dicoumarol is a chemical compound that is used in medicine to prevent and treat blood clots. It is also known as dicumarol or bishydroxycoumarin. Some synonyms for dicoumarol include coumadin, warfarin, and Marevan. These drugs are commonly used in anticoagulant therapy to prevent the formation of blood clots in patients with heart attacks, stroke, deep vein thrombosis, and other related conditions. Dicoumarol and its synonyms work by inhibiting the synthesis of vitamin K-dependent clotting factors, which are essential for blood clotting. However, it is important to use these medications under the supervision of a healthcare professional as they can have serious side effects and interactions with other drugs.
