Myostibin
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.
