# 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).

The BE recommendations identified in this notice were developed using the process described in that guidance. Elsewhere in this issue of the                         **Federal Register**                        , FDA is announcing the availability of final product-specific BE recommendations.                    

# DATES:

Submit written or electronic comments on the draft and revised draft product-specific BE recommendations listed in this notice by September 8, 2009.

# SUPPLEMENTARY INFORMATION:

## I. Background

                    In the                     **Federal Register**                     of May 31, 2007 (72 FR 30388), FDA announced the availability of a draft guidance for industry entitled “Bioequivalence Recommendations for Specific Products” that explained the process that would be used to make product-specific BE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/​cder/​guidance/​bioequivalence/​default.htm*. As described in that draft guidance, FDA adopted this process as a means to develop and disseminate product-specific BE recommendations and provide a meaningful opportunity for                           ( print page 27147)                        the public to consider and comment on those recommendations. Under that process, draft recommendations are posted on FDA's Web site and announced periodically in the                     **Federal Register**                    . The public is encouraged to submit comments on those recommendations within 90 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 September 5, 2008 (73 FR 51829). This notice announces draft product-specific recommendations, either new or revised, that have been posted on FDA's Web site in the period from May 1, 2008, through October 31, 2008. Final product-specific recommendations are being announced elsewhere in this issue of the                     **Federal Register**                    .
