Excipients used in pharmaceutical compounding
Preparations require excipients to impart a variety of properties to the compounded dosage form. From the compounder’s viewpoint, it is prudent to understand the role of each ingredient in the completed preparation. Many times this insight may alert the compounder to potential instabilities that might occur, clues about the preparation’s performance that would be useful/necessary to share with the patient, or provide alternatives if the preparation is not suitable for a patient due to allergies, preferences, etc. Also, excipients have different roles in different preparations, or oftentimes an excipient will play more than one role in a preparation.
