概覽
去鐵胺是一種重金屬螯合劑,主要用作鐵中毒的解毒劑。快速靜脈注射可能引起嚴重的低血壓和過敏反應。
作用機轉
Deferoxamine chelates iron by binding to free iron (Fe3+) in the blood and tissues, forming a stable, water-soluble complex called ferrioxamine.
Free Iron + Deferoxamine → Ferrioxamine complex → Excreted in the urine.
安全性與警告
禁忌症
- Severe renal disease
不良反應
- Pain at IM injection site
- Anaphylactic reactions (especially with rapid IV)
- Hypotension (if administered rapidly IV)
注意事項
Normal precautions should be observed. Do not administer rapidly intravenously due to the high risk of hypotension and anaphylaxis. Use slow IV infusion instead.
監測
- Serum iron levels
- Total iron-binding capacity (TIBC)
- Blood pressure (especially during IV infusion)
- Renal function (BUN, Creatinine)
- Urine color
藥物動力學
吸收
Well absorbed after IM administration.
分佈
Distributes widely but does not readily cross the blood-brain barrier.
代謝
Metabolized by plasma enzymes.
排除
The deferoxamine-iron complex (ferrioxamine) is excreted primarily in the urine.
過量
Overdosage or rapid IV administration can lead to acute hypotension, tachycardia, and shock. Treatment is supportive, including IV fluids and slowing/stopping the infusion.
