Excipients are defined as any component(s) of a dosage form other than the drug substance. They are added for the purposes of enhancing production, aiding patient acceptability, improving stability and/or controlling release. Moreover, they play an important role in enhancing the processability and bioavailability of drugs by modifying their solubility and/or permeability, which is important information when selecting excipients for any new formulation. This article by Dr Carolina Diaz Quijano from OMYA explores the potential of minerals such as functionalised calcium
carbonate, and what kind of formulations it will make possible in the near future.
