# 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 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 to develop and disseminate product-specific BE recommendations and to provide a meaningful opportunity for the public to consider and comment on those recommendations. This notice announces the availability of revised draft BE recommendations for lamotrigine extended-release tablets.

On May 29, 2009, FDA initially approved new drug application 022115 for LAMICTAL (lamotrigine) extended-release tablets. There are eight approved ANDAs for this product. In April 2010, we issued a draft guidance for industry on BE recommendations for lamotrigine extended-release tablets, which we subsequently revised in May 2010; July 2010; and August 2010. We are now issuing a further revised draft guidance for industry on BE recommendations for generic lamotrigine extended-release tablets (“Draft Guidance on Lamotrigine”).

In October 2006, UCB, Inc., submitted a citizen petition requesting that FDA       ( print page 4917)    take several actions with respect to anti-epileptic drugs (AEDs), including that FDA narrow the bioequivalence range for all such drugs (Docket No. FDA-2006-P-0461). FDA is reviewing the issues raised in the petition. Although lamotrigine is not the sole focus of the petition, lamotrigine is discussed and it is indicated for use as an AED; therefore, FDA will consider any comments on the draft guidance on lamotrigine in responding to the petition.

This draft guidance is being issued consistent with FDA's good guidance practices regulation (21 CFR 10.115). The draft guidance, when finalized, will represent the Agency's current thinking on the design of BE studies to support ANDAs for lamotrigine extended-release tablets. It does not create or confer any rights for or on any person and does not operate to bind FDA or the public. You can use an alternative approach if it satisfies the requirements of the applicable statutes and regulations.
