Ticlopidine is primarily used as an antiplatelet medication to prevent blood clots in patients who are at risk of stroke, heart attack, or other cardiovascular events. It is often prescribed for individuals who have recently undergone procedures like coronary artery stenting, as it helps reduce the risk of clot formation on the stent. Additionally, it is used for patients who cannot tolerate other antiplatelet drugs, such as aspirin or clopidogrel. Ticlopidine works by inhibiting platelet aggregation, which prevents the platelets from sticking together and forming clots. It is particularly useful in managing conditions like transient ischemic attacks (TIAs) and peripheral arterial disease. However, due to potential side effects like neutropenia and thrombotic thrombocytopenic purpura, its use is closely monitored, and it is often considered a second-line treatment.
