# ACTION:

Notice.

# SUMMARY:

                         The Food and Drug Administration (FDA) is announcing the availability of final 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                      **Federal Register**                         of May 31, 2007, FDA announced the availability of a draft guidance for industry entitled “Bioequivalence Recommendations for Specific Products” explaining the process that would be used to make product-specific BE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 notice were developed using the process described in that guidance. Elsewhere in this issue of the                         **Federal Register**                        , FDA is announcing the availability of additional draft and revised draft product-specific BE recommendations.

# 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            **Federal Register**                     of May 31, 2007 (72 FR 30388), FDA announced the availability of a draft guidance for industry entitled “Bioequivalence Recommendations for Specific Products” that explained the process that would be used to make product-specific BE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 As described in that draft guidance, FDA adopted this process as a means to develop and disseminate product-specific BE recommendations and provide a meaningful opportunity for the public to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. Once finalized, the recommendations are posted on FDA's Web site and announced in the                     **Federal Register**                    . This notice announces product-specific recommendations that have been posted on FDA's Web site from May 1, 2008, through October 31, 2008. Additional draft and revised draft product-specific BE recommendations are being announced elsewhere in this issue of the                     **Federal Register**                    .
