硝酸甘油貼片（Nitroglycerin patch）用於預防心絞痛。連續使用會產生藥物耐受性（Tolerance），即藥物效果隨時間減弱。因此，臨床建議設置「無藥物間隔期」（Nitrate-free interval），通常為 10-12 小時，讓身體組織休息以重新恢復對藥物的敏感度，通常建議於睡前移除。
The nurse should instruct the client to remove the nitroglycerin patch at bedtime to establish a daily nitrate-free interval. This 10- to 12-hour break prevents the development of drug tolerance, ensuring the medication remains effective for angina prophylaxis.
