Anhydrous dibasic calcium phosphate is a calcium salt of phosphoric acid. It is used as a diluent in pharmaceutical industry, in some toothpastes as a polishing agent. Calcium phosphate is generally recognized as safe by FDA. Dibasic calcium phosphate is ised as a supplement to treat conditions associated with calcium deficit, such as bone loss (osteoporosis), weak bones (osteomalacia/rickets), decreased activity of the parathyroid gland (hypoparathyroidism), and a certain muscle disease (latent tetany)

Hypocalcemia 75 Sources: https://www.drugs.com/mmx/calcium-phosphate-dibasic.html	Primary	Approved 8429	Unknown Approved Use Hypocalcemia, chronic (treatment) — Oral calcium supplements provide a source of calcium ion for treating calcium depletion occurring in conditions such as chronic hypoparathyroidism, pseudohypoparathyroidism, osteomalacia, rickets, chronic renal failure, and hypocalcemia secondary to the administration of anticonvulsant medications. When chronic hypocalcemia is due to vitamin D deficiency, oral calcium salts may be administered concomitantly with vitamin D analogs. However, calcium phosphate should not be used in patients with hypoparathyroidism or renal failure, since phosphate levels may be too high and giving more phosphate would exacerbate the condition. Calcium supplements should not be used in hyperparathyroidism, unless the need for a calcium supplement is high and the patient is carefully monitored. For treatment of hypocalcemia, supplementation is preferred

oral: 500 to 2000 mg elemental calcium a day, in divided doses (bid-qid). inhalation: In a single-blind, phase 1B proof of concept study, 24 subjects were enrolled to sequentially receive three doses of PUR118 (calcium lactate inhalation powder (CLIP) formulation) (5.5 mg, n = 18; 11.0 mg, n = 18; 2.8 mg, n = 16). Each dose was inhaled 3 times (1, 13, 25 h, preceded by 2 puffs salbutamol) before the ozone exposure (250 ppb, 3 h intermittent exercise). Sputum was induced 3 h after the end of exposure.
