Pharmacology

Fluoride Ion is considered a trace element, fluoride is any combination of elements containing the fluorine atom in the -1 oxidation state (fluoride ion). Due to its reactivity, fluorine is found in nature as fluorine compounds or fluorides. Fluoride inhibits various enzyme systems, erythrocyte glycolysis and binds Ca++, causing anticoagulation and other toxic effects. In addition, fluoride is a mitogen for osteoblasts and stimulates bone formation. (NCI)
