國際標準化比值(INR)主要用於監測維生素 K 拮抗劑(VKA)類藥物的抗凝血療效。Warfarin 是最常見的 VKA,而 Acenocoumarol 亦屬於同類藥物,兩者皆需透過 INR 監測以維持在目標治療區間。Heparin 監測 aPTT,而阿斯匹靈與保栓通(Clopidogrel)屬於抗血小板藥物,無常規凝血指標需監測。
The International Normalized Ratio (INR) is used to monitor the anticoagulant effect of vitamin K antagonists (VKAs). Warfarin and acenocoumarol are both VKAs, so their therapy requires regular INR monitoring to maintain therapeutic levels. In contrast, heparin is monitored via aPTT, while aspirin and clopidogrel are antiplatelet agents that do not require routine INR testing.
