A low-dose tablet contains 80 milligrams (mg) of aspirin, compared with 325 mg in a regular strength tablet. However, an analysis of data from major studies does not support the use of aspirin as a preventive medicine in people who have not had a heart attack, stroke or heart problems. low-dose tablet contains 80 milligrams (mg) of aspirin, compared with 325 mg in a regular strength tablet.

Introduction. Aspirin is an antiplatelet medicine, which means it reduces the risk of clots forming in your blood. This reduces your risk of having a stroke or heart attack. Normally, when there is a cut or break in a small blood vessel, a blood clot forms to plug the hole until the blood vessel heals.ow-dose aspirin (usually 75mg a day) may be given to you if you have had: 1  a heart attack. 2  a stroke or transient ischemic attack (TIA). 3  acute coronary syndrome (minor heart attack or unstable angina). 4  a coronary artery bypass operation. 5  a bioprosthetic heart valve.
