# 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, 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 notice were developed using the process described in that guidance.                     

# DATES:

 Although you can comment on any guidance at any time (see 21 CFR 10.115(g)(5)), to ensure that the Agency considers your comments on these draft and revised draft guidances before it begins work on the final versions of the guidances, submit either electronic or written comments on the draft and revised draft product-specific BE recommendations listed in this notice by May 21, 2012.

                    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 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 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,                           ( print page 16843)                        2012 (77 FR 3777).
