Clinical Trial Summary

Current guidelines recommend the addition of proton pump inhibitors (PPI) to patients taking double anti-platelet therapy (Aspirin and Clopidogrel) to prevent upper GI bleeding1. Many post percutaneous coronary intervention (PCI) patients are treated with dual anti-platelet medications as well as PPI to prevent upper GI bleeding.

Recently, it was shown that PPI interact with the P450 system in the liver and reduce the platelet inhibitory effect of Clopidogrel2,3. Clopidogrel is activated by CYP2C19, which also metabolizes PPI4. Furthermore, a recent article showed increased mortality in patients taking PPI and clopidogrel compared with patients taking clopidogrel without PPI protection5. The degree of reduction in the platelet inhibitory properties of clopidogrel might vary among the different PPI4.

The use of PPI for GI protection in patients treated with dual anti-platelet therapy is not based on randomized trials, but rather on expert opinion. Since H2 blockers are also effective in preventing acid secretion and are not known to interact with the P450 system that affects clopidogrel, the investigators hypothesized that these group of drugs will not interfere with the positive antiplatelet effects of clopidogrel and therefore will offer a good alternative treatment option.


Clinical Trial Description

In this study we will compare 3 different anti-acids regimens and their effect on platelet function ;
