Pharmaceutical products Specialty fillers, like precipitated calcium carbonate or silica, provide catalytic and aesthetic enhancements like binding, taste and texture. When blended with other specialty, non-active ingredients, they can deliver valuable functional attributes, like particle disintegration or time release. They also improve the process of making the tablets by either preventing moisture caking that clogs equipment or serving as an absorbent to carry viscous liquid actives and other materials. An effective acid neutralizer, PCC is often used in calcium-based antacid tablets and liquids. Being high in calcium content, PCC enables the formulation of high dosage calcium supplements and multi-vitamin/mineral tablets.
