HIDE SMILES / InChI
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, 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

PRIMARY Description: A white, amorphous powder; odourless or almost odourless. Solubility: Practically insoluble in water and ethanol (~750 g/l) TS; soluble in hydrochloric acid (~70 g/l) TS and nitric acid (~130 g/l) TS. Category: Tablet diluent. Storage: Calcium phosphate should be kept in a well-closed container. Additional information: At relative humidities between 15% and 65%, the equilibrium moisture content at 25 ?C is about 2%, but at relative humidities above 75% small additional amounts of moisture are absorbed. Definition: Calcium phosphate is a mixture consisting mainly of Ca3(PO4)2 together with CaHPO4. Calcium phosphate contains not less than 34.0% and not more than the equivalent of 40.0% of calcium, Ca, calculated with reference to the ignited substance.
