Dược Lực Học :
The mode of action of sodium stibogluconate is not clearly understood. In vitro exposure of amastigotes to 500 mg pentavalent antimony/ml results in a greater than 50% decrease in parasite DNA, RNA protein and purine nucleoside triphosphate levels. It has been postulated that the reduction in ATP (adenosine triphosphate) and GTP (guanosine triphosphate) synthesis contributes to decreased macromolecular synthesis.
Cơ Chế Tác Dụng :
Sodium stibogluconate is a medicine used to treat leishmaniasis and is only available for administration by injection. It belongs to the class of medicines known as the pentavalent antimonials. Sodium stibogluconate is sold in the UK as Pentostam (manufactured by GlaxoSmithKline). Widespread resistance has limited the utility of sodium stibogluconate, and in many parts of the world, amphotericin or miltefosine are used instead. It is also being investigated as an anti-tumor agent.
Sodium stibogluconate directly inhibits DNA topoisomerase I leading to inhibition of both DNA replication and transcription.
Độc Tính :
The main symptoms of antimony overdosage are gastro-intestinal disturbances (nausea, vomiting and severe diarrhoea). Haemorrhagic nephritis and hepatitis may also occur.
Chỉ Định :
For the treatment of various types of a protozoal infection called leishmaniasis, which may result from sandfly bites in tropical and temperate parts of the world. Also investigated for use/treatment in cancer/tumors (unspecified) and solid tumors.
Liều Lượng & Cách Dùng :
Solution - Intravenous
