Loop 利尿劑如 Furosemide 若給予速度過快，會導致耳毒性（Ototoxicity）。標準給藥速度為每分鐘不超過 20-40 mg，以確保藥物能穩定進入血液循環。雖然評估聽力（D）很重要，但預防毒性的關鍵在於「給藥速度」。
Rapid administration of loop diuretics such as furosemide can cause ototoxicity. The standard rate of administration is no more than 20-40 mg per minute, ensuring stable entry of the drug into the circulation. Although assessing hearing (D) is important, the key to preventing toxicity lies in controlling the rate of administration.
