[Docket Nos. FDA-2022-P-2752 and FDA-2022-P-3125]
Determination That Lithium Citrate Oral Solution, 8
Milliequivalents/5 Milliliters, Was Not Withdrawn From Sale for Reasons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 lithium citrate oral solution, 8 milliequivalents
(mEq)/5 milliliters (mL), was not withdrawn from sale for reasons of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.
FOR FURTHER INFORMATION CONTACT: Caitlin Callahan, Center for Drug
Evaluation and Research, Food and Drug Administration, 10903 New
Hampshire Ave., Bldg. 51, Rm. 6240, Silver Spring, MD 20993-0002, 240-
402-4318, [email protected].
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FDA determines that the listed drug was withdrawn from sale for reasons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determine on its own initiative, whether a listed drug was withdrawn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.
Lithium citrate oral solution, 8 mEq/5 mL, is the subject of NDA
018421, held by Hikma Pharmaceuticals USA Inc., and initially approved
on December 23, 1980.\1\ Lithium citrate oral

solution is a mood-stabilizing agent indicated as monotherapy for the
following treatment of bipolar I disorder: treatment of acute manic and
mixed episodes in patients 7 years and older; and maintenance treatment
in patients 7 years and older.
---------------------------------------------------------------------------
\1\ In their citizen petitions, petitioners Saptalis
Pharmaceuticals LLC, and Hyman, Phelps & McNamara, P.C., refer to
this drug product, respectively, as ``Lithium Citrate Syrup EQ 300
mg Carbonate/5mL'' and ``Lithium Citrate Oral Syrup, 300 mg
Carbonate/5mL.'' The currently approved labeling refers to this drug
product as ``Lithium Oral Solution USP, 8 mEq per 5 mL'' and
provides that the dosage strength for Lithium Oral Solution in terms
of lithium content, 8 mEq/5mL, is equivalent to 300 mg lithium
carbonate/5 mL. For purposes of this determination, we use the
current label's description, ``Lithium Oral Solution USP, 8 mEq per
5 mL.''
---------------------------------------------------------------------------
Lithium citrate oral solution, 8 mEq/5 mL, is currently listed in
the ``Discontinued Drug Product List'' section of the Orange Book.
Saptalis Pharmaceuticals, LLC submitted a citizen petition dated
November 2, 2022 (Docket No. FDA-2022-P-2752), under Sec. 10.30 (21
CFR 10.30), requesting that the Agency determine whether lithium
citrate oral solution, 8 mEq/5 mL, was withdrawn from sale for reasons
of safety or effectiveness. Hyman, Phelps & McNamara, P.C. separately
submitted a citizen petition dated December 6, 2022 (Docket No. FDA-
2022-P-3125), under Sec. 10.30, requesting that the Agency make the
same determination.
After considering the citizen petitions and reviewing Agency
records and based on the information we have at this time, FDA has
determined under Sec. 314.161 that lithium citrate oral solution, 8
mEq/5 mL, was not withdrawn for reasons of safety or effectiveness. The
Petitioners have identified no data or other information suggesting
that lithium citrate oral solution, 8 mEq/5 mL, was withdrawn for
reasons of safety or effectiveness. We have carefully reviewed our
files for records concerning the withdrawal of lithium citrate oral
solution, 8 mEq/5 mL, from sale. We have also independently evaluated
relevant literature and data for possible postmarketing adverse events.
We have found no information that would indicate that this drug product
was withdrawn from sale for reasons of safety or effectiveness.
Accordingly, the Agency will continue to list lithium citrate oral
solution, 8 mEq/5 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.
