5 Pharmacology and Biochemistry
5.1 MeSH Pharmacological Classification

Chelating Agents

Chemicals that bind to and remove ions from solutions. Many chelating agents function through the formation of COORDINATION COMPLEXES with METALS. (See all compounds classified as Chelating Agents.)


Radiopharmaceuticals

Compounds that are used in medicine as sources of radiation for radiotherapy and for diagnostic purposes. They have numerous uses in research and industry. (Martindale, The Extra Pharmacopoeia, 30th ed, p1161) (See all compounds classified as Radiopharmaceuticals.)
