anticoagulant

An anticoagulant is a medication that helps prevent blood clots from forming or growing. Blood clots are necessary to stop bleeding, but sometimes they form when not needed, leading to risks like strokes or heart attacks. Anticoagulants work by interfering with the blood's clotting process, making it less likely for clots to develop. They are prescribed for conditions such as atrial fibrillation, deep vein thrombosis, or after certain surgeries. Patients on these medications need regular monitoring to balance preventing clots while avoiding excessive bleeding.
