Calcium preparations are often administered to ensure that adequate calcium levels are available in the body for various physiologic needs, including bone formation. Specifically, calcium supplements can be used to help prevent bone loss in conditions such as osteoporosis, osteomalacia, rickets, and hypoparathyroidism. For instance, calcium supplements alone cannot prevent osteoporosis in postmenopausal...

Drug-Drug and Drug-Food Interactions. Drugs commonly used in the CKD population that may decrease absorption of oral iron include calcium preparations and antacids. Oral iron may also decrease the absorption of quinolone antibiotics. Medications that increase gastric pH such as H2-antagonists and proton pump inhibitors may also decrease iron absorption since iron absorption in the duodenum is maximized at an acidic pH. 

During the catarrhal phase calcium preparations with vitamin C parenterally, preparations calming the coughing and the pains, absolute bed rest. 

During the subsiding phase calcium preparations and vitamin C ampoules applied together venally every 4 hours glucocorticoids - at average treatment doses. 

Pulmo-protective treatment inhalation of aerosol mixture (see above), diuretics (Furanthril, Mannitol etc. parenterally, calcium preparations and vitamin C - ampoules). 

Pulmo-protective medication - calcium preparations and vitamin C ampoule combined applied venally, codein preparations combined with analgin and expectorating syrups perorally, inhalation of solution containing sodium bicarbonate, cortison preparations, Novphyllin etc. - upon indication. 

Calcium preparations can be given PO in tablet, capsule, or powder form or IV. If given IV, then mix with 5% dextrose in water. Do not mix with a saline solution because sodium encourages the loss of calcium. 

Employees should be informed of the risks of exposure to corrosive agents and be well trained to handle the chemicals as well as to act when they have been exposed. Showers for rapid irrigation with water should be easily accessible. A 1% copper sulfate solution, polyethylene glycol 300 or 400, 5% sodium thiosulfate solution, and a proper calcium preparation should be present in the first-aid kit. A calcium preparation for topical treatment should also be present near any employees work site where hydrofluoric acid or fluorides are used. Workers at risk should wear proper protective equipment, which may include eye glasses, face masks, gloves, boots, and safety dresses. 

After Davy s first calcium preparation the development of alternative methods was limited. At the end of the 19 century, Henri Moissan in France, the discoverer of fluorine, prepared the element by reduction of calcium iodide with potassium. From the beginning of the 20 century, production was based on the electrolysis of fused calcium chloride.
