Effect of tegoprazan on temporal variability of platelet reactivity in patients treated with clopidogrel after coronary stenting
Abstract
Background/aims: Data on the interactions between clopidogrel and tegoprazan are limited. We compared the effects of tegoprazan and proton-pump inhibitors (PPIs) on platelet reactivity.
Methods: Using database data from March 2020 to January 2023, we retrospectively evaluated 262 patients who were taking either tegoprazan (n = 107) or PPIs (n = 155) combined with dual antiplatelet therapy, including aspirin and clopidogrel, after percutaneous coronary intervention. Platelet reactivity was assessed using VerifyNow P2Y12 assays.
Results: Platelet reaction unit (PRU) values at 3 (157 ± 8 vs. 162 ± 6, p = 0.659), 6 (167 ± 9 vs. 158 ± 7, p = 0.370), and 12 months (155 ± 10 vs. 164 ± 7, p = 0.448) were similar between groups. The prevalence of high on-treatment platelet reactivity, defined as ≥ 253 PRU, was also similar between the groups at 3 (10.3% vs. 10.2%, p = 0.976), 6 (7.0% vs. 8.2%, p = 1.000), and 12 months (4.3% vs. 9.0%, p = 0.503).
Conclusion: There was no significant difference in platelet reactivity between the tegoprazan and PPI groups in patients undergoing PCI and receiving dual antiplatelet therapy with clopidogrel.
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 262 participants or records.
