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.

Why is 81 mg and not 80 mg the aspirin dose for children?   This is a vestige of the old system of measuring medications in grains. Follow the math, 1 grain = 64.79 mg 5 grains = standard aspirin dose = 323.99 mg or about oâ¦ur current dose of 325 mg. When we started doing research on the efficacy of Aspirin; we found that for cardiac prevention half of the standard dose was effective (i.e. 162.5 mg). Then we figured out that half of the new dose would also work or 81mg .... This is at least the story that is passed down in medical school ...
