Excipients Browser

The Excipients Browser was created with support from a CERSI grant from the FDA. Any errors of omission or commission in the database are the responsibility of the Irwin and Shoichet labs. Please report any error or provide feedback about the database. You must use the database at your own risk. The goal of the project is to curate and disseminate information about excipients, the assumed-inactive substances found in food and drugs. This includes: colors, flavors, stabilizers, bulking and delivery agents, fillers, packaging, and other purposes.

Molecular

Explore small molecule excipients.

Oral

Explore excipients that are administered orally.

Unresolved

Explore non-molecular or ambiguous excipients.

Rarely Used

Explore excipients that are rarely used.

The aim of this project is to encourage innovation in drug delivery and formulation by providing easily accessible and searchable information about these important yet often overlooked substances.

The excipients browser is an active project undergoing rapid change. We welcome your feedback, whether it is a question you may have, or perhaps an error you would like to report. Many pages have a comment section at the bottom, where you can tell us what you think! We also welcome feedback by email to chemistry4biology@gmail.com or on twitter at @chem4biology.
