What is adenosine diphosphate inhibitor?

Adenosine diphosphate inhibitors (ADP inhibitors) are a class of drugs that are used to prevent blood clots from forming. ADP is a molecule that is involved in the activation of platelets, which are cells in the blood that are responsible for clotting. When platelets are activated, they clump together to form a clot, which can block blood flow and lead to a heart attack or stroke.

ADP inhibitors work by blocking the receptors on the surface of platelets that normally bind to ADP, preventing activation and clumping. This reduces the risk of blood clots forming and can prevent heart attacks and strokes.

Some common ADP inhibitors include clopidogrel, ticagrelor, and prasugrel. These drugs are often used in combination with other antiplatelet drugs, such as aspirin, to provide additional protection against blood clots.

However, ADP inhibitors can also increase the risk of bleeding, so they must be used with caution in patients who are at risk for bleeding disorders. Patients taking ADP inhibitors should also be monitored closely for signs of bleeding and other side effects.
