Calcium carbonate?

Hello and welcome!

Calciparine (internationally known as acidum acetylsalicylicum+calcii carbonas) is a medication used as an analgesic, antipyretic, and anti-inflammatory.

As a matter of fact, it not only contains of acetylsalicylic acid, but also of calcium carbonate. The question is - why is it so?

Though I have a sneaking suspicion that calcium would be dissolved given it was not a carbonate, I am still not certain whether I am right?

Thanks in advance.
Haiduc.

This is just buffered aspirin. The calcium carbonate acts to maintain a specific pH range in the stomach and thus hopefully reduce any stomach upset the aspirin might cause.
