# ACTION:

Notice.

# SUMMARY:

                        The Food and Drug Administration (FDA) is announcing the availability of additional draft and revised draft product-specific bioequivalence (BE) recommendations. The recommendations provide product-specific guidance on the design of BE studies to support abbreviated new drug applications (ANDAs). In the                         **Federal Register**                         of June 11, 2010 (75 FR 33311), FDA announced the availability of a guidance for industry entitled “Bioequivalence Recommendations for Specific Products,” which explained the process that would be used to make product-specific BE recommendations available to the public on FDA's Web site. The BE recommendations identified in this document were developed using the process described in that guidance.                    

# DATES:

# SUPPLEMENTARY INFORMATION:

## I. Background

                    In the                     **Federal Register**                     of June 11, 2010, FDA announced the availability of a guidance for industry entitled “Bioequivalence Recommendations for Specific Products,” which explained the process that would be used to make product-specific BE recommendations available to the public on FDA's Web site at                     *http://www.fda.gov/​Drugs/​GuidanceComplianceRegulatoryInformation/​Guidances/​default.htm.*                     As described in that guidance, FDA adopted this process as a means to develop and disseminate product-specific BE recommendations and provide a meaningful opportunity for the public to consider and comment on those recommendations. Under that process, draft recommendations are posted on the FDA's Web site and announced periodically in the                     **Federal Register.**                     The public is encouraged to submit comments on those recommendations within 60 days of their announcement in the                     **Federal Register.**                     FDA considers any comments received and either publishes final recommendations or publishes revised draft recommendations for comment. Recommendations were last announced in the                     **Federal Register**                     of January 25, 2012 (77 FR 3777). This notice announces draft product-specific recommendations, either new or revised, that have been posted on the FDA's Web site in the period from July 1, 2011, through November 30, 2011.                

                    For a complete history of previously published                     **Federal Register**                     notices relating to product-specific BE recommendations, please go to                     *http://www.regulations.gov*                     and enter docket number FDA-2007-D-0369.                

These draft and revised draft guidances are being issued consistent with FDA's good guidance practices regulation (21 CFR 10.115). The guidances represent the Agency's current thinking on product-specific design of BE studies to support ANDAs. They do not create or confer any rights for or on any person and do not operate to bind FDA or the public. An alternative approach may be used if such approach satisfies the requirements of the applicable statutes and regulations.
