CYP2C19 loss-of-function alleles and use of omeprazole or esomeprazole increase the risk of cardiovascular outcomes in patients using clopidogrel.
Our aim was to investigate in a real-life prospective patient cohort how CYP2C19 loss-of-function (LOF) variants and CYP2C19 inhibitor omeprazole or esomeprazole influence the incidence of cardiovascular events in patients using clopidogrel. Data based simultaneously on these factors are conflicting and sparse. A cohort of prospective patients (n = 1972) with acute coronary syndrome (n = 1302) or symptomatic chronic coronary disease (n = 656) was followed for 365 days after hospitalization with information on purchased prescription drugs, hospital discharge, death, and genotype for CYP2C19*2, CYP2C19*3, and CYP2C19*8 LOF variants. The primary study outcome measurement was cardiovascular death or recurring myocardial infarction or stroke. Altogether, 608 patients (30.8%) carried CYP2C19 LOF alleles. During the 365-day follow-up 252 patients (12.8%) had an ischemic vascular event. Cardiovascular events were significantly more frequent in carriers of CYP2C19 LOF alleles (14.8%, 95% confidence interval [CI], 11.7-17.8) than in non-carriers (10.8%, 95% CI, 9.0-12.6, p = 0.0159). Omeprazole or esomeprazole use was similar among LOF allele carriers (n = 131, 21.5%) and non-carriers (n = 250, 18.3%, p = 0.185). Cardiovascular events were significantly more common in a composite group consisting of all CYP2C19 LOF carriers regardless of proton pump inhibitor use status and non-carriers using omeprazole or esomeprazole than in non-carriers not using omeprazole or esomeprazole (14.8%, 95% CI, 12.2-17.3 vs. 9.9%, 95% CI, 8.0-11.9, p = 0.00173). We observed significantly more cardiovascular events in carriers of CYP2C19 LOF variants and in non-carriers using omeprazole or esomeprazole. For optimal patient care, both genetics and concomitant medication should be considered.

Comparative risk of ischemic stroke among users of clopidogrel together with individual proton pump inhibitors.
There is controversy and little information about whether individual proton pump inhibitors (PPIs) differentially alter the effectiveness of clopidogrel in reducing ischemic stroke risk. We, therefore, aimed to elucidate the risk of ischemic stroke among concomitant users of clopidogrel and individual PPIs.. We conducted a propensity score-adjusted cohort study of adult new users of clopidogrel, using 1999 to 2009 Medicaid claims from 5 large states. Exposures were defined by prescriptions for esomeprazole, lansoprazole, omeprazole, rabeprazole, and pantoprazole-with pantoprazole serving as the referent. The end point was hospitalization for acute ischemic stroke, defined by International Classification of Diseases Ninth Revision Clinical Modification codes in the principal position on inpatient claims, within 180 days of concomitant therapy initiation.. Among 325 559 concomitant users of clopidogrel and a PPI, we identified 1667 ischemic strokes for an annual incidence of 2.4% (95% confidence interval, 2.3-2.5). Adjusted hazard ratios for ischemic stroke versus pantoprazole were 0.98 (0.82-1.17) for esomeprazole; 1.06 (0.92-1.21) for lansoprazole; 0.98 (0.85-1.15) for omeprazole; and 0.85 (0.63-1.13) for rabeprazole.. PPIs of interest did not increase the rate of ischemic stroke among clopidogrel users when compared with pantoprazole, a PPI thought to be devoid of the potential to interact with clopidogrel.

Risk of adverse cardiovascular outcomes and all-cause mortality associated with concomitant use of clopidogrel and proton pump inhibitors in elderly patients.
To examine the effect of concomitant use of clopidogrel and PPIs in a national sample of elderly Medicare beneficiaries (age ≥65 years).. A nested case-control design was employed. A cohort of Medicare beneficiaries who initiated clopidogrel and did not have any gap of ≥30 days between clopidogrel fills between July 1, 2006 and December 31, 2008 was identified from a 5% national sample of Medicare claims data. Within this cohort, cases (beneficiaries who experienced any major cardiovascular event [MCE] [acute myocardial infarction, stroke, coronary artery bypass graft, or percutaneous coronary intervention] or all-cause mortality) and controls (beneficiaries who did not experience any MCE or all-cause mortality) were identified from inpatient and outpatient claims. Cases and controls were matched on age and the time to first clopidogrel fill. Conditional logistic regression was performed on the matched sample to evaluate the association between concomitant use of clopidogrel and PPIs and adverse health outcomes (MCEs and all-cause mortality).. A total of 43,159 clopidogrel users were identified. Among them, 15,415 (35.7%) received clopidogrel and a PPI concomitantly at any time during the study period, 3502 (8.1%) experienced a MCE, 7306 (17.1%) died, and a total of 9908 (22.8%) experienced the primary composite outcome (any MCE or all-cause mortality) during follow-up. The odds ratio (OR) for the primary composite outcome was 1.26 (95% confidence interval [CI]: 1.18-1.35). Secondary analyses indicated that elderly patients using clopidogrel and a PPI concomitantly were more likely to experience all-cause mortality (OR: 1.40; 95% CI: 1.29-1.53) as compared to those receiving clopidogrel only, but not MCEs (OR: 1.06; 95% CI: 0.95-1.18).. Concomitant use of clopidogrel and PPIs was associated with a slightly increased risk of all-cause mortality but not MCEs.
