Calcium Phosphate

Excipient (pharmacologically inactive substance)
What is it?
Various calcium phosphates are used as diluents in the pharmaceutical industry. Diluents are added to pharmaceutical tablets or capsules to make the product large enough for swallowing and handling, and more stable.[1]
Some calcium phosphate salts can be anhydrous, meaning the water has been removed from the salt form. Other calcium phosphates are termed dibasic, meaning they have two replaceable hydrogen atoms.
There is no evidence in the available information on calcium phopshate that demonstrates or suggests reasonable grounds to suspect a hazard to the public when they are used at levels that are now current or that might reasonably be expected in the future.[2]
