Sod. Stibogluconate

Uses

Leishmaniasis, Visceral leishmaniasis

Sod. Stibogluconate is also used to associated treatment for these conditions: Leishmaniasis, Mucocutaneous Leishmaniasis, Visceral Leishmaniasis

How Sod. Stibogluconate works

Sodium stibogluconate directly inhibits DNA topoisomerase I leading to inhibition of both DNA replication and transcription.

Dosage

Sod. Stibogluconate dosage

Leishmaniasis:20 mg/kg/day (maximum 850 mg) intramuscularly or intravenously for 20 to 28 days.

Side Effects

Sodium stibogluconate is exceedingly toxic to veins. One of the practical problems is that after a few doses it can become exceedingly difficult to find a vein in which to inject the drug. The insertion of a PICC does not prevent the problem and can instead exacerbate it: the entire vein along the course of the PICC line can become inflamed and thrombose. Large doses of sodium stibogluconate are often administered as dilute solutions.

Pancreatitis is a common deleterious effect of the drug, and the serum amylase or lipase should be monitored twice weekly; there is no need to stop treatment if the amylase remains less than four times the upper limit of normal; if the amylase rises above the cut-off, then treatment should be interrupted until the amylase falls to less than twice the upper limit of normal, whereupon treatment can be resumed. Cardiac conduction disturbances are less common, but ECG monitoring while the medicine is injected is advisable and changes quickly reverse after the drug is stopped or the infusion rate is decreased.

The drug can be given intramuscularly but is exceedingly painful when given by this route. It can also be given intralesionally when treating cutaneous leishmaniasis (i.e., injected directly into the area of infected skin) and again, this is exceedingly painful and does not give results superior to intravenous administration.

Sodium stibogluconate can also cause a reduced appetite, metallic taste in mouth, nausea, vomiting, diarrhoea, headache, tiredness, joint pains, muscle aches, dizziness, and anaphylaxis.

Toxicity

The main symptoms of antimony overdosage are gastro-intestinal disturbances (nausea, vomiting and severe diarrhoea). Haemorrhagic nephritis and hepatitis may also occur.
