# SUPPLEMENTARY INFORMATION:

## 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,” which explained the process that would be used to make product-specific guidances available to the public on FDA's Web site at                     *https://www.fda.gov/​Drugs/​GuidanceComplianceRegulatoryInformation/​Guidances/​default.htm.*

As described in that guidance, FDA adopted this process to develop and disseminate product-specific guidances and to provide a meaningful opportunity for the public to consider and comment on the guidances. This notice announces the availability of draft product-specific guidances for generic salmeterol xinafoate inhalation powder, fluticasone propionate inhalation aerosol, and fluticasone propionate inhalation powder.

FDA initially approved new drug application (NDA) 020692 for SEREVENT DISKUS (salmeterol xinafoate inhalation powder) in September 1997. We are now issuing a draft guidance for industry on, among other things, BE recommendations for generic salmeterol xinafoate inhalation powder (“Draft Guidance on Salmeterol Xinafoate”).

FDA initially approved NDA 021433 for FLOVENT HFA (fluticasone propionate inhalation aerosol) in May 2004 and NDA 020833 for FLOVENT DISKUS 100 (fluticasone propionate inhalation powder) in September 2000. We are now also issuing two draft guidances for industry on, among other things, BE recommendations for generic fluticasone propionate inhalation aerosol and fluticasone propionate inhalation powder (both entitled “Draft Guidance on Fluticasone Propionate”).

In December 2009, GlaxoSmithKline (GSK), manufacturer of the reference listed drugs SEREVENT DISKUS, FLOVENT HFA, and FLOVENT DISKUS 100, submitted a citizen petition requesting that FDA withhold approval of any ANDA or 505(b)(2) application for generic oral inhalation products containing salmeterol xinafoate and/or fluticasone propionate unless certain conditions were satisfied, including conditions related to demonstrating BE (Docket No. FDA-2009-P-0597). FDA is reviewing the issues raised in the petition. FDA will consider any comments on guidances entitled, “Draft Guidance on Salmeterol Xinafoate” or “Draft Guidance on Fluticasone Propionate,” before responding to GSK's citizen petition.

                    The draft guidances are being issued consistent with FDA's good guidance practices regulation (21 CFR 10.115). The draft guidances, when finalized, will represent the current thinking of FDA on, among other things, the design of BE studies to support ANDAs for salmeterol xinafoate inhalation powder, fluticasone propionate inhalation aerosol, and fluticasone propionate inhalation powder. They do not establish any rights for any person and are not binding on FDA or the public. You can use an alternative approach if it satisfies the requirements of the applicable statutes and regulations. These guidances are not subject to Executive Order 12866.                          ( print page 48825)    

## II. Electronic Access

                    Persons with access to the internet may obtain the draft guidances at either                     *https://www.fda.gov/​Drugs/​GuidanceComplianceRegulatoryInformation/​Guidances/​default.htm*                     or                     *https://www.regulations.gov.*
