呋塞米
別名: Lasix, Salix, Disal, Dimazon, Frusecare, Frusedale, Libeo, Frusol
呋塞米（通常以商品名 Lasix 為人所知）是一種強效的**利尿劑**或「水丸」，用於幫助您的寵物排出體內多餘的水分。它最常被開立用於治療心力衰竭或肺部積水。 > **重要提示：** 因為這種藥物會從體內排除水分，您的寵物排尿次數會明顯增加，尿量也會變大。**請務必確保您的寵物隨時有充足的新鮮飲水**，以防止嚴重脫水。 * **居家監測：** 如果您的寵物正在接受心臟病治療，獸醫可能會要求您計算寵物的**休息呼吸頻率**（睡眠時每分鐘的呼吸次數）。這是確保藥物劑量正確的關鍵工具。 * **何時聯繫獸醫：** 如果您注意到脫水或電解質不平衡的跡象，例如過度口渴極度嗜睡、虛弱、焦躁不安、排尿減少、嘔吐或心跳過快，請立即聯繫您的獸醫。 * **給藥：** 請嚴格遵循獸醫的給藥指示。在未諮詢獸醫的情況下，請勿自行更改劑量，因為清除積水和導致脫水之間的平衡非常微妙。
劑量必須由獸醫依你寵物的個別情況決定。切勿在沒有獸醫指導下給予人類藥物或其他寵物的處方藥。

給藥方式
可能的副作用
- Fluid and electrolyte abnormalities (hyponatremia, hypokalemia, hypocalcemia, hypomagnesemia)
- Prerenal azotemia (secondary to dehydration)
- Ototoxicity (especially in cats with high-dose IV therapy)
- Gastrointestinal distress
- Hematologic effects (anemia, leukopenia)
- Weakness and restlessness
- Hypokalaemia
- Hypochloraemia
- Hypocalcaemia
- Hypomagnesaemia
- Hyponatraemia
- Dehydration
- Polyuria/polydipsia (PU/PD)
- Prerenal azotaemia
注意事項與禁忌
- Anuria
- Hypersensitivity to furosemide
- Progressive renal disease if increasing azotemia and oliguria occur during therapy
- Seriously depleted electrolytes
- Severe dehydration
- Severe electrolyte depletion
- Hepatic coma
- Dehydration
- Pericardial effusion where cardiac tamponade is confirmed
- Use with caution in patients with pre-existing electrolyte or water balance abnormalities, impaired hepatic function (may precipitate hepatic coma), and diabetes mellitus. Monitor carefully in patients with conditions leading to fluid loss (e.g., vomiting, diarrhea). Patients hypersensitive to sulfonamides may also be hypersensitive to furosemide. Ensure animals have normal food and water intake to prevent imbalances.
藥物相互作用
- ACE INHIBITORS (e.g., enalapril, benazepril): Increased risks for hypotension, particularly in patients who are volume or sodium depleted secondary to diuretics
- AMINOGLYCOSIDES (gentamicin, amikacin, etc.): Increased risk for ototoxicity
- AMPHOTERICIN B: Loop diuretics may increase the risk for nephrotoxicity development; hypokalemia
- CORTICOSTEROIDS: Increased risk for GI ulceration; hypokalemia
- DIGOXIN: Furosemide-induced hypokalemia may increase the potential for digoxin toxicity
- INSULIN: Furosemide may alter insulin requirements
- MUSCLE RELAXANTS, NON-DEPOLARIZING (e.g., atracurium, tubocurarine): Furosemide may prolong neuromuscular blockade
- PROBENECID: Furosemide can reduce uricosuric effects
- SALICYLATES: Loop diuretics can reduce the excretion of salicylates
- SUCCINYLCHOLINE: Furosemide may potentiate effects
- THEOPHYLLINE: Pharmacologic effects of theophylline may be enhanced when used with furosemide
