葡萄糖酸銻鈉
葡萄糖酸銻鈉是一種五價銻化合物,主要用於治療犬隻的利什曼原蟲症(Leishmaniasis)。在美國無市售,需透過疾病管制與預防中心(CDC)取得。此藥物具有潛在的嚴重副作用,需謹慎使用。
作用機制: The exact mechanism of action of sodium stibogluconate remains incompletely elucidated. * **Prodrug Hypothesis:** It is widely hypothesized to act as a prodrug, where the pentavalent antimony (SbV) is reduced to the more toxic trivalent antimony (SbIII) within the host macrophage or the parasite itself. * **Bioenergetic Disruption:** It is believed to interfere with the parasite's bioenergetics by reducing **ATP and GTP synthesis** in susceptible *Leishmania* amastigotes, ultimately leading to parasite death.
各物種劑量

過量
In the unlikely event of a parenterally administered overdose, it is suggested to immediately contact an animal poison control center. * **Chelation Therapy:** Potentially, antimony toxicity can be managed by chelating agents such as **dimercaptosuccinic acid (DMSA)** or **d-penicillamine** to enhance excretion.
