Determination That ENDEP (Amitriptyline Hydrochloride) Oral 
Concentrate, 40 Milligrams/Milliliter, Was Not Withdrawn From Sale for 
Reasons of Safety or Effectiveness

AGENCY: Food and Drug Administration, HHS.

ACTION: Notice.

-----------------------------------------------------------------------

SUMMARY: The Food and Drug Administration (FDA or Agency) has 
determined that ENDEP (amitriptyline hydrochloride) oral concentrate, 
40 milligrams (mg)/milliliter (mL), was not withdrawn from sale for 
reasons of safety or effectiveness. This determination will allow FDA 
to approve abbreviated new drug applications (ANDAs) for ENDEP 
(amitriptyline hydrochloride) oral concentrate, 40 mg/mL, if all other 
legal and regulatory requirements are met.

SUPPLEMENTARY INFORMATION: Section 505(j) of the Federal Food, Drug, 
and Cosmetic Act (FD&C Act) (21 U.S.C. 355(j)) allows the submission of 
an ANDA to market a generic version of a previously approved drug 
product. To obtain approval, the ANDA applicant must show, among other 
things, that the generic drug product: (1) has the same active 
ingredient(s), dosage form, route of administration, strength, 
conditions of use, and (with certain exceptions) labeling as the listed 
drug, which is a version of the drug that was previously approved, and 
(2) is bioequivalent to the listed drug. ANDA applicants do not have to 
repeat the extensive clinical testing otherwise necessary to gain 
approval of a new drug application (NDA).
    Section 505(j)(7) of the FD&C Act requires FDA to publish a list of 
all approved drugs. FDA publishes this list as part of the ``Approved 
Drug Products With Therapeutic Equivalence Evaluations,'' which is 
known generally as the ``Orange Book.'' Under FDA regulations, drugs 
are removed 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FDA determines that the listed drug was withdrawn from sale for reasons 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 (21 CFR 314.162).
    A person may petition the Agency to determine, or the Agency may 
determine on its own initiative, whether a listed drug was withdrawn 
from sale for reasons of safety or effectiveness. This determination 
may be made at any time after the drug has been withdrawn from sale, 
but must be made prior to approving an ANDA that refers to the listed 
drug (Sec.  314.161 (21 CFR 314.161)). FDA may not approve an ANDA that 
does not refer to a listed drug.
    ENDEP (amitriptyline hydrochloride) oral concentrate, 40 mg/mL, is 
the subject of ANDA 085749, held by Hoffman-La Roche Inc., and 
initially approved on December 23, 1977. ENDEP (amitriptyline 
hydrochloride) oral concentrate, 40 mg/mL, is indicated for relief of 
symptoms of depression.
    Hoffman-La Roche Inc. has never marketed ENDEP (amitriptyline 
hydrochloride) oral concentrate, 40 mg/mL. ANDA 085749 is listed in the 
``Discontinued Drug Product List'' section of the Orange Book.
    Hyman, Phelps & McNamara, P.C., submitted a citizen petition dated 
January 11, 2022 (Docket No. FDA-2022-P-0068), under 21 CFR 10.30, 
requesting that the Agency determine whether ENDEP (amitriptyline 
hydrochloride) oral concentrate, 40 mg/mL, was withdrawn from sale for 
reasons of safety or effectiveness.
    After considering the citizen petition and reviewing Agency records 
and based on the information we have at this time, FDA has determined 
under Sec.  314.161 that ENDEP (amitriptyline hydrochloride) oral 
concentrate, 40 mg/mL, was not withdrawn for reasons of safety or 
effectiveness. The petitioner has identified no data or other 
information suggesting that ENDEP (amitriptyline hydrochloride) oral 
concentrate, 40 mg/mL, was withdrawn for reasons of safety or 
effectiveness. We have carefully reviewed our files for records 
concerning the withdrawal of ENDEP (amitriptyline hydrochloride) oral 
concentrate, 40 mg/mL, from sale. We have also independently evaluated 
relevant literature and data for possible postmarketing adverse events. 
We have reviewed the available evidence and determined that this drug 
product was not withdrawn from sale for reasons of safety or 
effectiveness.
    Accordingly, the Agency will continue to list ENDEP (amitriptyline 
hydrochloride) oral concentrate, 40 mg/mL, 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. ANDAs that refer to ENDEP (amitriptyline hydrochloride) 
oral concentrate, 40 mg/mL, may be approved by the Agency as long as 
they meet all other legal and regulatory requirements for the approval 
of ANDAs. If FDA determines that labeling for this drug product should 
be revised to meet current standards, the Agency will advise ANDA 
applicants to submit such labeling.

Associate Commissioner for Policy.
