Gallium nitrate injection is a clear, colorless, odorless, sterile solution of gallium nitrate, a
hydrated nitrate salt of the group IIIa element, gallium. Gallium nitrate is formed by the reaction
of elemental gallium with nitric acid, followed by crystallization of the drug from the solution.
The stable, nonahydrate, Ga(N03)3•9H2O is a white, slightly
hygroscopic, crystalline powder of molecular weight 417.87, that is readily soluble in water. Each
mL of Ganite (gallium nitrate injection) contains gallium nitrate 25 mg (on an anhydrous basis) and
sodium citrate dihydrate 28.75 mg. The solution may contain sodium hydroxide or hydrochloric acid
for pH adjustment to 6.0-7.0.
