I. Background

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” that explained the process that would be used to make product-specific guidances available to the public on FDA's Web site at​Drugs/​GuidanceComplianceRegulatoryInformation/​Guidances/​default.htm.

As described in that guidance, FDA adopted this process as a means to develop and disseminate product-specific guidances and provide a meaningful opportunity for the public to consider and comment on those guidances. Under that process, draft guidances 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 guidances or publishes revised draft guidances for comment. Final product-specific guidances were last announced in the Federal Register on September 21, 2015 (80 FR 57000). This notice announces final product-specific guidances that are posted on FDA's Web site.
