Decoagulant, also known as anticoagulant, is a substance that prevents blood from clotting. There are several synonyms for decoagulant, including antithrombotic, antithrombotic agent, blood thinner, and clotting factor inhibitor. These terms are commonly used in the medical field to describe medications or treatments that prevent blood clots, which can lead to serious health complications such as stroke or heart attack. Antithrombotic is often used to describe drugs that prevent the formation of blood clots, while blood thinner refers to medications that prevent the blood from clotting. Clotting factor inhibitors are medications that block the specific proteins responsible for blood clotting.
