ABSTRACT
Objective To investigate the unusual drug-induced International Normalized Ratio(INR) change in elderly patients with warfarin treatment and its related mechanism. Methods A retrospective analysis was performed in 41 cases of elderly patients with unusual drug-induced INR change from 2011 to 2015 in Tongji Hospital,Tongji Medical College,Huazhong University of Science and Technology. Results INR was increased unusually in 37 cases(90.2%) and was decreased unusually in 4 cases(9.8%).Intravenous drugs(80.5%) were prone to cause unusual INR change.Prostaglandin,antifungal drugs,antiarrhythmic drugs and lipid soluble vitamins were the commonly used drugs that induced adverse reaction,accounting for 26.8%,29.3%,29.3% and 9.8%,respectively. Conclusion Unusual drug-induced INR change is not rare in elderly patients with warfarin treatment during hospitalization.When other drugs are prescribed,INR should be measured more frequently and the dose of warfarin should be adjusted promptly.
