Plavidosa contains the active substance clopidogrel, a platelet aggregation blocker. Platelets are very small structures which clump together (aggregate) during blood clotting. By preventing formation of blood clots (thrombi) in hardened blood vessels, clopidogrel reduces the risk of stroke or heart attack.
Plavidosa is used if you have hardening of the arteries (atherosclerosis), and you have either:
- Had a recent heart attack (myocardial infarction) or previous stroke, or
- The active substance is clopidogrel (as clopidogrel besilate).
