Aspirin Enteric-Coated Tablets: Guide for Cardiovascular and Cerebrovascular Thrombosis Prevention

　　Aspirin enteric-coated tablets are a widely used clinical antithrombotic medication.Its core pharmacological action is to irreversibly inhibit the activity of cyclooxygenase-1(COX-1)in platelets,block the production pathway of thromboxane A2(TXA2),thereby potently inhibiting platelet aggregation and preventing thrombosis,playing a central role in the prevention of cardiovascular and cerebrovascular diseases.

　　The core indicated populations of this product fall into two main categories.The first is the secondary prevention population for cardiovascular and cerebrovascular diseases,including patients who have had myocardial infarction,stroke,coronary heart disease,or have undergone stent implantation surgery.Long-term standardized administration can significantly reduce the risk of disease recurrence.The second is the primary prevention population for cardiovascular and cerebrovascular diseases,who have not experienced related cardiovascular and cerebrovascular events but have risk factors such as hypertension,diabetes,hyperlipidemia,long-term smoking,and family history of cardiovascular and cerebrovascular diseases.Only after a comprehensive assessment of the benefits of medication and the risk of bleeding by a professional physician can the decision to initiate medication be made,and blind self-administration is strictly prohibited.

　　The enteric-coated formulation design of aspirin enteric-coated tablets is core to reducing the risk of gastrointestinal irritation from the drug.This formulation allows the tablet to remain undissolved in the acidic environment of the stomach,and release the active pharmaceutical ingredient only after smoothly entering the alkaline environment of the intestine,greatly reducing direct irritation of the drug to the gastric mucosa,and lowering the incidence of adverse reactions such as stomach discomfort,gastritis,gastric ulcer,and even gastrointestinal bleeding.Based on the characteristics of this formulation,this product is recommended to be taken on an empty stomach before meals to accelerate the passage of the tablet through the stomach into the intestine and ensure the enteric coating effect.

　　Although this product has a clear antithrombotic effect,it is not suitable for all populations.People with active gastrointestinal bleeding,active peptic ulcer,severe hepatic and renal insufficiency,allergy to aspirin or other non-steroidal anti-inflammatory drugs(NSAIDs),a history of aspirin-induced asthma,and bleeding tendency should be prohibited from use or used with caution under the close supervision of a physician.During medication,close attention should be paid to bleeding-related signals,such as abnormal gingival bleeding,unexplained skin ecchymosis or bruising,and melena.Once found,medical attention should be sought immediately.

　　For people taking this product for a long time,sudden discontinuation of medication without medical advice is strictly prohibited.Sudden drug withdrawal may lead to a rebound increase in platelet activity,which instead greatly increases the risk of thrombosis.At the same time,concomitant use with NSAIDs such as ibuprofen should be avoided as much as possible,as these drugs may competitively bind to the relevant action sites on platelets and weaken the antiplatelet effect of aspirin.In addition,aspirin was often used for antipyretic and analgesic purposes in the past,but currently,due to the risk of gastrointestinal irritation and the potential for Reye's Syndrome in children taking it,paracetamol or ibuprofen are more recommended for clinical antipyretic and analgesic use,and the core clinical application of this product has been focused on the field of cardiovascular and cerebrovascular protection.

　　It is important to specially remind that aspirin enteric-coated tablets are prescription drugs,not health supplements.The necessity of medication,timing of medication initiation,daily dosage(the conventional recommended dosage is 75-100mg daily),and treatment course must be evaluated and formulated by a professional physician according to the individual's physical condition.Do not take it blindly for a long time by self-judgment of"benefits",so as to avoid unnecessary bleeding risk and even cover up other underlying diseases.Only standardized medication under the guidance of a physician can maximize the clinical value of the drug and safely protect cardiovascular and cerebrovascular health.
