Abstract:

Clopidogrel, a prodrug is found to be less effective in inhibiting the platelet aggregation when administered along with PPI’s and statins in patients undergoing cardiac stent, ST segment elevated Myocardial infarction (STEMI) followed by percutaneous coronary intervention (PCI). Clopidogrel binds to CYP2C19, a hepatic enzyme to get converted to its active metabolite in order to achieve desired pharmacological activity. The cytochrome P450 3A4 which is partially involved in the metabolism of clopidogrel also metabolizes PPIs like omeprazole, lansoprazole and pantoprazole; statins, mainly atorvastatin, rosuvastatin and simvastatin to the greater extent. In the current study, patients on PPI’s with dual antiplatelet therapy and patients on PPI’s and statins with dual antiplatelet therapy are considered to understand the potential drug–drug interactions (pDDI) among the South Asian population. Platelet aggregation was measured in 91 patients undergoing coronary artery stent implantation treated with clopidogrel and aspirin along with PPI’s and statins. It was observed that lansoprazole and simvastatin, but not omeprazole, pantoprazole and atorvastatin, rosuvastatin, inhibited the antiplatelet activity of clopidogrel. The percent platelet aggregation was 81 ± 2 (p = 0.012), 72 ± 6 (p = 0.001), and 43 ± 23 (p = 0.027) in the presence of clopidogrel with lansoprazole, omeprazole and pantoprazole respectively. Aggregation was found to be 91 ± 4 (p = 0.001), 51 ± 3 (p = 0.009) and 12 ± 23 (p = 0.031) in the presence of clopidogrel with atorvastatin and rosuvastatin respectively. A prominent drug–drug interaction was observed with patients on dual antiplatelet therapy along with lansoprazole and simvastatin.
