Also, certain medicines, suchas proton pump inhibitors Prilosec (omeprazole) and Nexium (esomeprazole), reduce the effect of clopidogrel, leaving a person at greater risk for heart attack and stroke.
On its face, that could set up a situation where only KUDco and AstraZeneca can sell Prilosec in the U.S. Such a result would keep the cost of the drug, also known asomeprazole, relatively high.
