Fluoride is derived from fluorine, an element with unique properties that are ideal for synthesizing drugs. Fluorine is the most electronegative element and can substitute for hydrogen in medicinal compounds, making the compound stronger and more stable, acidic and lipophilic. These qualities increase the bioavailability of the drug and its ability to attach to binding sites on cellular receptors and enzymes. Fluorine-containing drugs are used to treat dental disease, neuropsychiatric disorders, cancer, infections and heart disease.
