`Dear Ms.Vaughn:
`
`
`Please refer to your supplemental new drug application dated January 18, 2008, received
`
`January 22, 2008, submitted under section 505(b) of the Federal Food, Drug, and Cosmetic Act for
`Fortamet (metformin HCl extended-release) Tablets.
`
`We acknowledge receipt of your submission dated July 17, 2008.
`
`
`This supplemental application is in response to our supplement request letter dated
`November 19, 2007, and proposes labeling revisions to the DESCRIPTION, INDICATIONS AND
`
`
` USAGE, and PRECAUTIONS sections of the package insert.
`
`We have completed our review of this application, as amended. This application is approved, effective
`on the date of this letter, for use as recommended in the agreed-upon labeling text.
`
` As soon as possible, but no later than 14 days from the date of this letter, please submit the content of
`
`labeling [21 CFR 314.50(l)] in structured product labeling (SPL) format as described at
` http://www.fda.gov/oc/datacouncil/spl.html that is identical to the enclosed labeling (text for the
`
`
` package insert) submitted July 17, 2008). Upon receipt, we will transmit that version to the National
` Library of Medicine for public dissemination. For administrative purposes, please designate this
`
`submission, “SPL for approved NDA 21-574.”
`
` We remind you that you must comply with reporting requirements for an approved NDA
