Injection USP) 25 Milligrams/Milliliter, 10 Milliliters, Was Not

AGENCY: Food and Drug Administration, HHS.
ACTION: Notice.
-----------------------------------------------------------------------
SUMMARY: The Food and Drug Administration (FDA) has determined that
PHENERGAN (promethazine hydrochloride (HCl) injection USP) 25
milligrams (mg)/milliliter (mL), 10 mL, was not withdrawn from sale for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 promethazine
HCl injection USP 25 mg/mL, 10 mL.

SUPPLEMENTARY INFORMATION: In 1984, Congress enacted the Drug Price
Competition and Patent Term Restoration Act of 1984 (Public Law 98-417)
(the 1984 amendments), 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 ANDAs 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 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 Under FDA regulations, drugs are withdrawn from the list if the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drug was withdrawn from sale for reasons of safety or effectiveness (21
CFR 314.162).
Under Sec. 314.161(a)(1) (21 CFR 314.161(a)(1)), the agency must
determine whether a listed drug was withdrawn from sale for reasons of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. FDA may not approve an ANDA that does not refer to a
listed drug.
PHENERGAN (promethazine HCl injection USP) 25 mg/mL, 10 mL, is the
subject of approved NDA 08-857 held by Wyeth Pharmaceuticals, a
division of Wyeth. PHENERGAN (promethazine HCl injection USP) 25 mg/mL,
10 mL, is indicated for certain types of allergic reactions and
sedation. In a citizen petition dated March 25, 2002 (Docket No. 02P-
0127), submitted under Sec. 314.161 and 21 CFR 10.30, PharmaForce,
Inc., requested that the agency determine whether PHENERGAN
(promethazine HCl injection USP) 25 mg/mL, 10 mL, was withdrawn from
sale for reasons of safety or effectiveness. The petitioner seeks this
determination in preparation for filing an ANDA for promethazine HCl
injection USP 25 mg/mL, 10 mL.
The agency has determined that Wyeth's PHENERGAN (promethazine HCl
injection USP) 25 mg/mL, 10 mL, was not withdrawn from sale for reasons
of safety or effectiveness. In support of this finding, we note that
Wyeth continues to market PHENERGAN for injection in 25 mg/mL and 50
mg/mL, 1-mL vials. The 25 mg/mL, 10 mL product is a multidose vial
consisting of the same drug as the 25 mg/mL and 50 mg/mL, 1-mL vials.
Also, promethazine HCl is a widely used product that has been marketed
for many decades in many dosage forms. Although one potential concern
with any multidose injectable product is the possibility of accidental
overdose, there is no evidence that the withdrawal from the market of
PHENERGAN (promethazine HCl injection) 25 mg/mL, 10 mL, was in any way
connected to accidental overdose. FDA has independently evaluated
relevant literature and data for adverse event reports and has found no
information that would indicate this product was withdrawn for reasons
of safety or effectiveness.
After considering the citizen petition and reviewing its records,
FDA determines that, for the reasons outlined previously, Wyeth's
PHENERGAN (promethazine HCl injection USP) 25 mg/mL, 10 mL, was not
withdrawn from sale for reasons of safety or effectiveness.
Accordingly, the agency will continue to list PHENERGAN (promethazine
HCl injection USP) 25 mg/mL, 10 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 PHENERGAN (promethazine HCl
injection USP) 25 mg/mL, 10 mL, may be approved by the agency.
