FDA says it will be making changes to its inactive ingredient database (IID) that provides information on inactive ingredients present in FDA-approved drugs. The information can be used by industry as an aid in developing new drugs, an agency [notice](http://s2027422842.t.en25.com/e/es?s=2027422842&e=244857&elqTrackId=376c7bc788024cd5a73d955f2e3dcbdc&elq=5d8ccdabf2ae4e81ae0b89331f40accf&elqaid=9147&elqat=1&ref=fdaweb.com) says.

The notice says FDA will use a phased approach to make additional changes to the IID to improve data consistency and accuracy. In phase 1, new data standards will be applied for route of administration, dosage form, and units of measure.

Under the GDUFA 2 reauthorization, FDA committed to amending the IID in significant ways by 10/2020\. It said it would update the IID by 10/1/20 to facilitate queries for accurate maximum daily intake and maximum daily exposure information. It also committed to posting quarterly notices of updates made to the database.
