— Explanation · 中文詳解 —
Warfarin 是維生素 K 拮抗劑,其療效監測指標為凝血酶原時間的國際標準化比值(INR)。一般治療範圍視適應症而定(通常為 2.0-3.0)。aPTT 用於監測 Heparin,而非 Warfarin。
Warfarin is a vitamin K antagonist, and its therapeutic effect is monitored using the International Normalized Ratio (INR). While aPTT is used for heparin, INR provides the standard measurement for assessing warfarin efficacy and safety.
