It belongs to a group of medications known as the pentavalent antimonials. Bio Farma vaccine produced vaccines against measles, polio, hepatitis B, and pentavalent vaccine. In India, almost all infections are resistant to pentavalent antimonials. In Africa, a combination of pentavalent antimonials and paromomycin is recommended. This row would begin with a trivalent lanthanum, a teravalent cerium, and a pentavalent didymium. Sodium stibogluconate is in the pentavalent antimonials class of medication. They are also called pentavalent antimony compounds. Prior to Werner, the models of amine complexes postulated chains of pentavalent nitrogen centers. Bismuth forms trivalent and pentavalent compounds, the trivalent ones being more common. True pentavalent carbon is unlikely; methanium, nominally , usually exists as . The traditional treatment is with pentavalent antimonials such as sodium stibogluconate and meglumine antimoniate. The pentavalent oxidation state of americium was first observed in 1951. A dopant with five valence electrons is also called a pentavalent impurity. The company started manufacturing its flagship vaccine product, Pentavalent (DTP Hib HepB) in 2008. Other pentavalent dopants are antimony (Sb) and bismuth (Bi).
