          - [Docket No. 00P-0585] 

# AGENCY:

Food and Drug Administration, HHS. 

# ACTION:

Notice. 

# SUMMARY:

The Food and Drug Administration (FDA) is announcing its determination that fluoxetine hydrochloride 20-milligram (mg) tablets (Prozac®) were not withdrawn from sale for reasons of safety or effectiveness. This determination will allow FDA to approve abbreviated new drug applications (ANDA's) for fluoxetine hydrochloride 20-mg tablets.

# SUPPLEMENTARY INFORMATION:

In 1984, Congress enacted the Drug Price Competition and Patent Term Restoration Act of 1984 (the 1984 amendments) (Public Law 98-417), which authorized the approval of duplicate versions of drug products approved under an ANDA procedure. ANDA sponsors must, with certain exceptions, show that the drug for which they are seeking approval contains the same active ingredient in the same strength and dosage form as the “listed drug,” which is a version of the drug that was previously approved under a new drug application (NDA). Sponsors of ANDA's do not have to repeat the extensive clinical testing otherwise necessary to gain approval of an NDA. The only clinical data required in an ANDA are data to show that the drug that is the subject of the ANDA is bioequivalent to the listed drug. 

                    The 1984 amendments include what is now section 505(j)(7) of the Federal Food, Drug, and Cosmetic Act (21 U.S.C. 355(j)(7)), which requires FDA to publish a list of all approved drugs. FDA publishes this list as part of the “Approved Drug Products With                           ( print page 38562)                        Therapeutic Equivalence Evaluations,” which is generally known as the “Orange Book.” Under FDA regulations, drugs are withdrawn from the list if the agency withdraws or suspends approval of the drug's NDA or ANDA for reasons of safety or effectiveness, or if FDA determines that the listed drug was withdrawn from sale for reasons of safety or effectiveness (§ 314.162 (21 CFR 314.162)). Regulations also provide that the agency must make a determination as to whether a listed drug was withdrawn from sale for reasons of safety or effectiveness before an ANDA that refers to that listed drug may be approved (§ 314.161(a)(1) (21 CFR 314.161(a)(1))). FDA may not approve an ANDA that does not refer to a listed drug.                 

On February 11, 2000, Lachman Consultant Services, Inc., submitted a citizen petition (Docket No. 00P-0585/CP1) under 21 CFR 10.30 to FDA. The petition requested that the agency determine whether fluoxetine hydrochloride 20-mg tablets were withdrawn from sale for reasons of safety or effectiveness. Fluoxetine hydrochloride 20-mg tablets are the subject of NDA 20-974. FDA approved NDA 20-974, held by Eli Lilly and Co., on March 9, 1999. On April 2, 1999, Eli Lilly and Co. informed FDA that it had decided not to market fluoxetine hydrochloride 20-mg tablets. FDA has determined that, for purposes of §§ 314.161 and 314.162, never marketing an approved drug product is equivalent to withdrawing the drug from sale. 

FDA has reviewed its records and, under § 314.161, has determined that Eli Lilly and Co.'s decision not to market fluoxetine hydrochloride 20-mg tablets was not for reasons of safety or effectiveness. Accordingly, the agency will continue to list fluoxetine hydrochloride 20-mg tablets in the “Discontinued Drug Product List” section of the Orange Book. The “Discontinued Drug Product List” delineates, among other items, drug products that have been discontinued from marketing for reasons other than safety or effectiveness. ANDA's that refer to fluoxetine hydrochloride 20-mg tablets may be approved by the agency.
