ASA-KOR 81 Low Dose Aspirin 81 mg Tablets are designed for adults and serve as a long-term preventive therapy under a doctor's supervision. This medication can also be life-saving if you suspect you are experiencing a heart attack. Daily low-dose aspirin therapy may be recommended for the primary prevention of heart attacks or strokes for individuals aged 40 to 59 who are at high risk of having their first heart attack or stroke within the next 10 years. Aspirin is classified as a salicylate and a nonsteroidal anti-inflammatory drug (NSAID) that works by blocking certain natural substances in the body to diminish pain and inflammation, plus it has anti-platelet aggregation effect. For this reason your doctor may recommend a low dose of aspirin to prevent blood clots, thereby reducing the risk of stroke and heart attack. If you have recently undergone surgery for clogged arteries, such as bypass surgery or coronary stenting, your doctor may advise using low-dose aspirin as a "blood thinner" to prevent clot formation.
