What is the indication for clopidogrel hydrogen sulfate tablets?

Clopidogrel hydrogen sulfate tablets are ADP receptor antagonists and antiplatelet agents widely used in clinical practice. They are particularly suitable for patients who cannot tolerate aspirin due to gastrointestinal adverse reactions and may serve as an alternative therapy in such cases. Clinically, this drug is indicated for the treatment of ischemic stroke, acute myocardial infarction, and peripheral arterial disease, helping to reduce the incidence of arterial occlusion.

Clopidogrel hydrogen sulfate can be administered long-term to inhibit platelet aggregation. It is also highly effective in the treatment of cerebral thrombosis. In cardiovascular diseases, it is primarily used in patients with severe vascular stenosis or acute myocardial infarction as one component of dual antiplatelet therapy (DAPT), commonly combined with aspirin (e.g., Bayer Aspirin^®). For patients with coronary artery disease or angina pectoris who are intolerant to aspirin, clopidogrel hydrogen sulfate tablets may be used as a substitute.

Clopidogrel hydrogen sulfate is also indicated for the prevention of stroke and peripheral arterial thrombotic disorders; its efficacy is superior to that of aspirin, although it is relatively more expensive. Long-term use may cause gastric mucosal ulcers, abdominal pain, and diarrhea. Additionally, allergic reactions may occur, manifesting as skin rashes accompanied by pruritus. If adverse effects arise during treatment, drug administration should be discontinued immediately, and medical attention sought promptly.
