— Explanation · 中文詳解 —
Warfarin 是維生素 K 拮抗劑，主要透過抑制凝血因子合成發揮作用。臨床上使用 PT（凝血酶原時間）及 INR（國際標準化比值）作為監測治療成效與調整劑量的主要依據，給藥前必須確認數值是否處於安全治療範圍內。
Warfarin is a vitamin K antagonist that works primarily by inhibiting the synthesis of clotting factors. Clinically, PT (prothrombin time) and INR (International Normalized Ratio) are used as the primary parameters for monitoring therapeutic effect and adjusting the dose. Before administration, the nurse must confirm that these values fall within the safe therapeutic range.
