摘要：

The present invention is directed to compositions comprising a nanoparticulate clopidogrel and aspirin combination, or salts or derivatives thereof, having improved clopidogrel bioavailability. The nanoparticulate clopidogrel particles, and optionally the nanoparticulate aspirin particles, of the composition have an effective average particle size of less than about 2000 nm and are useful in the prevention and treatment of pathologies induced by platelet aggregation. The clopidogrel and aspirin particles may also be formulated as a controlled release polymeric coating or matrix drug delivery system.
