Ozagrel sodium is primarily used as an antiplatelet agent to prevent blood clots. It works by inhibiting thromboxane A2 synthase, an enzyme involved in platelet aggregation. This makes it effective in treating conditions like cerebral thrombosis and improving blood flow in ischemic stroke patients. It is also used in managing peripheral vascular diseases and preventing re-occlusion after surgical procedures like angioplasty. Additionally, it has been explored for its potential in reducing inflammation and improving outcomes in certain cardiovascular and cerebrovascular disorders.
