Pentavalent antimonial
Pentavalent antimonials (also abbreviated pentavalent Sb or SbV) are a group of compounds used for the treatment of leishmaniasis. They are also called pentavalent antimony compounds.
Types
The first pentavalent antimonial used was urea stibamine: first introduced in the 1930s, it fell out of favour in the 1950s due to higher toxicity compared to sodium stibogluconate.
The compounds currently available for clinical use are:
- sodium stibogluconate (Pentostam; manufactured by GlaxoSmithKline; available in United States [through the Centers for Disease Control only] and UK), which is administered by slow intravenous injection.
- meglumine antimoniate (Glucantim; manufactured by Aventis; available in Brazil, France and Italy), which is administered by intramuscular or intravenous injection.[1]
The pentavalent antimonials can only be given by injection: there are no oral preparations available.
Alternatives
In many countries, widespread resistance to antimony has meant that amphotericin or miltefosine are now used in preference.[2]Wardha Refai, Nayani Madarasingha, Rohini Fernandopulle, Nadira Karunaweera (2016).

Side effects
Cardiotoxicity, reversible renal failure, pancreatitis, anemia, leukopenia, rash, headache, abdominal pain, nausea, vomiting, arthralgia, myalgia, thrombocytopenia, and transaminase elevation.
