Apixaban, a popular blood thinner, works by inhibiting the formation of blood clots. This makes it effective in treating and preventing various conditions, including stroke, deep vein thrombosis, and pulmonary embolism. However, like all medications, apixaban can have side effects, ranging from mild to serious. This article will explore the common and serious side effects of apixaban, providing valuable information for patients and healthcare providers.
Introduction to Apixaban
Apixaban is a prescription medication that belongs to a class of drugs known as anticoagulants, or blood thinners. It works by preventing blood clots from forming in the blood vessels, which can help reduce the risk of stroke, deep vein thrombosis (DVT), and pulmonary embolism (PE).
Apixaban is a newer type of anticoagulant that is taken orally and is generally well-tolerated by patients. It is used to treat and prevent various conditions related to blood clotting, making it a vital part of managing cardiovascular health.
Mechanism of Action
Apixaban inhibits the activity of a specific protein called factor Xa. Factor Xa plays a crucial role in the coagulation cascade, a complex series of steps that lead to the formation of blood clots. By blocking factor Xa, apixaban prevents the formation of thrombin, a key enzyme in the clotting process. This mechanism helps to reduce the risk of blood clots forming in the body.
