Excipients are inactive substances used in the formulation of medications to support the delivery of the active pharmaceutical ingredient (API).
They serve various roles, such as enhancing the stability, bioavailability, and absorption of the API, as well as improving the taste, texture, and overall usability of the drug.
Common excipients include binders, fillers, preservatives, colorants, and flavoring agents.
While they do not have therapeutic effects, excipients play a crucial role in ensuring the medication is safe, effective, and easy to administer.
Their selection is vital to the drug development process.
