Gallium nitrate (brand name Ganite) is the gallium salt of nitric acid with the chemical formula Ga(NO₃)₃. It is a drug used to treat symptomatic hypercalcemia secondary to cancer. It works by preventing the breakdown of bone through the inhibition of osteoclast activity, thus lowering the amount of free calcium in the blood. Gallium nitrate is also used to synthesize other gallium compounds.
