What is an antithrombotic?

An antithrombotic is a medication that prevents or treats the formation of blood clots (thrombosis) in blood vessels. They are used to treat and prevent a variety of conditions, including deep vein thrombosis (DVT), pulmonary embolism (PE), stroke, and heart attack.

Antithrombotics work by interfering with the blood clotting process. Some antithrombotics, such as aspirin and clopidogrel, inhibit the action of platelets, which are involved in the formation of blood clots. Others, such as warfarin and heparin, inhibit the action of clotting factors, which are proteins in the blood that are involved in the clotting process.

Antithrombotics can be used in combination with other medications, such as statins and angiotensin-converting enzyme (ACE) inhibitors, to reduce the risk of cardiovascular disease. They can also be used in conjunction with surgical procedures, such as stent placement and coronary artery bypass graft (CABG), to prevent blood clots from forming after the procedure.

Antithrombotics are generally safe and well-tolerated, but they can cause side effects, such as bleeding, nausea, and dizziness. It is important to talk to your doctor about the risks and benefits of antithrombotic therapy before starting treatment.
