Determination That COGENTIN (Benztropine Mesylate) Injection, 1 
Milligram per 1 Milliliter, Was Not Withdrawn From Sale for Reasons of 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 the Agency) has 
determined that COGENTIN (benztropine mesylate) Injection, 1 milligram 
(mg)/1 milliliter (mL), was not withdrawn from sale for reasons of 
safety or effectiveness. This determination means that FDA will not 
begin procedures to withdraw approval of abbreviated new drug 
applications (ANDAs) that refer to this drug product, and it will allow 
FDA to continue to approve ANDAs that refer to the product as long as 
they meet relevant legal and regulatory requirements.

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FDA determines that the listed drug was withdrawn from sale for reasons 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determine on its own initiative, whether a listed drug was withdrawn 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may be made at any time after the drug has been withdrawn from sale, 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 FDA's approval of 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.
    COGENTIN (benztropine mesylate) Injection, 1 mg/1 mL, is the 
subject of NDA 012015, held by Akorn Operating Company LLC, and 
initially approved on December 21, 1959. COGENTIN is indicated for use 
as an adjunct in the therapy of all forms of parkinsonism and for the 
control of extrapyramidal disorders (except tardive dyskinesia) due to 
neuroleptic drugs (e.g., phenothiazines).
    In a letter dated March 18, 2022, Akorn Operating Company LLC 
notified FDA that COGENTIN (benztropine mesylate) Injection, 1 mg/1 mL, 
was being discontinued, and FDA moved the drug product to the 
``Discontinued Drug Product List'' section of the Orange Book.
    Nexus Pharmaceuticals submitted a citizen petition dated May 19, 
2023 (Docket No. FDA-2023-P-2055), under 21 CFR 10.30, requesting that 
the Agency determine whether COGENTIN (benztropine mesylate) Injection, 
1 mg/1 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 COGENTIN (benztropine mesylate) Injection, 1 
mg/1 mL, was not withdrawn from sale for reasons of safety or 
effectiveness. The petitioner has identified no data or other 
information suggesting that this drug product was withdrawn for reasons 
of safety or effectiveness. We have carefully reviewed our files for 
records concerning the withdrawal of COGENTIN (benztropine mesylate) 
Injection, 1 mg/1 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 COGENTIN (benztropine 
mesylate) Injection, 1 mg/1 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. FDA will not begin procedures to withdraw approval of 
approved ANDAs that refer to this drug product. Additional ANDAs for 
this drug product may also 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.

    Dated: November 6, 2023.
Lauren K. Roth,
Associate Commissioner for Policy.
