For paper submissions, postal carrier packages MUST be addressed to the document room (include “ATTN: DOCUMENT ROOM” in the address label) in order for the submission to be processed and tracked. Failure to do so will delay reviewer receipt and review of submission. Please send all submissions (original abbreviated new drug applications (ANDAs) ANDA amendments, ANDA supplements, ANDA resubmissions, and controlled correspondence) to the OGD document room address below:

Generic Drug Petition Tracking

These petitions are submitted to FDA by drug companies seeking permission to file an abbreviated new drug application for a change from a listed drug in dosage form, strength, route of administration, or active ingredient in a combination product.   If FDA determines that the drug is suitable for a generic product, the petition is approved, if it is not suitable, the petition is denied.
  • Guidances
  • The Office of Generic Drugs has revised the draft Question-based Review Chemistry questions (PDF - 107KB). The generics industry is encouraged to go through the revised draft questions and provide any feedback or suggestions.
  • Inactive Ingredient Database 
    The newly revised Inactive Ingredients Database provides information on inactive ingredients present in FDA-approved drug products. This information can be used by industry as an aid in developing drug products.
  • Bioequivalence Study Retention Samples (1/12/2001) 
    Regulations state that applicants shall retain reserve samples of the tested products administered to study subjects and release these samples to FDA upon request. The Agency may then analyze these retention samples to ensure that the BA/BE results upon which FDA bases approval of New Drug Applications (NDA) and Abbreviated New Drug Applications (ANDAs) are reliable.
  • FDA Letters to Industry 
    This series of letters informs generic drug product manufacturers of policy and procedure developments with respect to the Drug Price Competition and Patent Term Restoration Act of 1984.
