Bismuth

Due to the formulatable pH range of 6 to 10, bismuth salts should not be combined with acidic components.

Bismuth compounds such as dibismuth tris(tetraoxodialuminate), bismuth oxide nitrate (bismuth subnitrate, basic bismuth nitrate) are used as part of a therapy against Helicobacter-duodeni (pylori) (eradication therapy).

Historically, bismuth was used as a component of wound powders (e.g. dermatol) at the end of the 19th century. Since the 1920s it has been used as a remedy for syphilis.

Bismuth gallate is mainly used in a formulation as a paste in combination with zinc oxide, for example Pasta exsiccans NRF 11.112. It is also listed under the same name by the SR.
