Abstract

Objective: To investigate signals and preventability of coagulation disorders related to anticoagulants in the National Pharmacovigilance database. Subject and method: A cross-sectional retrospective study of spontaneous ADR reports registered at the National DI & ADR Center from 2017 to 2021. Result: Out of 174 ADR reports on coagulation disorders related to anticoagulants, 100 (57.5%) reports were assessed as preventable ADRs (pADRs). Coagulation disorders were diverse with the highest reported rates of elevated INR (20.7%), administration site hemorrhage (19.5%), and gastrointestinal hemorrhage (19.0%). Signals were detected with acenocoumarol, enoxaparin, heparin, dabigatran, and rivaroxaban. Enoxaparin was the most common drug with pADRs (66 cases), followed by acenocoumarol (21 cases). Most pADRs were related to drug interactions (92 cases). Conclusion: The risk of coagulation disorders attributed to anticoagulants has been demonstrated by this study. To minimize adverse outcomes (especially hemorrhage) of these high-risk medications, risk management for anticoagulants in clinical settings should be implemented, focusing on potentially preventable causes identified in this study.
