Antacids High purity API for antacids

Imerys precipitated calcium carbonates (PCC) are excellent active pharmaceutical ingredients (API) for antacids designed to reduce excess stomach and gastric acid.

Imerys pharmaceutical-grade precipitated calcium carbonates contain alkaline ions that render stomach acid more neutral and counteract symptoms linked to excess stomach acid such as acid reflux, heartburn and indigestion.

We recommend our Calcius™ range for antacids.
