Calcium Gluconate is the calcium salt of gluconic acid, an oxidation product of glucose, and contains 9.3% calcium, which is about one-third of the calcium in strength of calcium chloride USP. It has molecular formula C₁₂H₂₂CaO₁₄ with a molecular weight of 430.38. Since it is soluble to the extent of only one proof in 30 parts of cold water, the 10% solution is supersaturated and is stabilized by the addition of calcium saccharate tetrahydrate 0.46% w/v (which supplies calcium 6.2%). Each mL contains 98 mg of calcium gluconate monohydrate, 4.6 mg of calcium saccharate tetrahydrate, and Water for Injection USP, q.s. Each mL provides 9.3 mg (0.465 milliequivalents) of calcium.

The 100 mL Pharmacy Bulk Package contains many single doses for use in a pharmacy admixture program in the preparation of parenteral fluids. See directions for dispensing from the 100 mL Pharmacy Bulk Package.

pH is adjusted with sodium hydroxide and/or hydrochloric acid.
