What is Calcium acetate?

Plain description, key identifiers and synonyms

Calcium acetate is the calcium salt of acetic acid. It is used, commonly as a hydrate, to treat hyperphosphataemia (excess phosphate in the blood) in patients with kidney disease: the calcium ion combines with dietary phosphate to form (insoluble) calcium phosphate, which is excreted in the faeces. It has a role as a chelator. It contains an acetate.

Pharmacology

Calcium Acetate is a calcium salt of acetic acid. Calcium is a mineral essential for many cellular functions including nerve impulse transmission, muscle contraction, cardiac function, bone formation, and capillary and cell membrane permeability. Calcium acetate is administered orally to prevent or treat calcium deficiency and to treat hyperphosphatemia due to its phosphate-binding properties.

How it is made

Action of pyroligneous acid on calcium hydroxide, the solution being filtered and evaporated to dryness yields gray acetate of lime. (Monohydrate)

Calcium acetate is produced by passing acetic acid vapor over heated lime
