Curator's Comment: description was created based on several sources, including https://www.alfa.com/en/catalog/043674/

Calcium lactate is the salt that consists of two lactate anions for each calcium cation (Ca2+); this salt is used as a calcium supplement to treat hypocalcemia. However, as a source of free calcium, this salt is less convenient than calcium citrate. Calcium lactate inhalation powder also called as PUR118 participated in phase I clinical trials to determine whether this formulation was safe and tolerable in a population of subjects with Cystic Fibrosis (CF). PUR118 also was used in another clinical trials to evaluate its effect on ozone-induced airway Inflammation in healthy normal volunteers in case of Chronic Obstructive Pulmonary Disease (COPD). The obtained results revealed that PUR118 reduced the severity of acute exacerbations in COPD and CF and had the beneficial impacts on mortality, morbidity, and quality of life in affected individuals. However, both studies were discontinued.

Hypocalcemia 73 Sources: https://www.drugs.com/mmx/calcium-phosphate-dibasic.html	Primary	Approved 8583	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
