Determination That Astemizole 10-Milligram Tablets Were Withdrawn
From Sale for Safety Reasons
AGENCY: Food and Drug Administration, HHS.
ACTION: Notice.
-----------------------------------------------------------------------
SUMMARY: The Food and Drug Administration (FDA) has determined that
astemizole 10-milligram (mg) tablets (Hismanal) were withdrawn from
sale for safety reasons. The agency will not accept or approve
abbreviated new drug applications (ANDA's) for astemizole 10-mg
tablets.
FOR FURTHER INFORMATION CONTACT: Andrea C. Masciale, Center for Drug
Evaluation and Research (HFD-7), Food and Drug Administration, 5600
Fishers Lane, Rockville, MD 20857, 301-594-2041.
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 approved innovator drug products under an ANDA procedure.
ANDA sponsors generally must 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 drug that
was previously approved under a new drug application (NDA). Sponsors of
ANDA's are not required to repeat the extensive clinical testing
necessary to gain approval of an NDA. The only data from investigations
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 Under FDA regulations, drugs are withdrawn from the list if the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drug was withdrawn from sale for reasons of safety or effectiveness
(Sec. 314.162 (21 CFR 314.162)). FDA may not approve an ANDA that does
not refer to a listed drug (21 CFR 314.92(a)).
Astemizole 10-mg tablets (Hismanal) are the subject of approved NDA
19-402, currently held by Janssen Pharmaceutica (Janssen). In 1988, FDA
approved the NDA for Hismanal tablets for the relief of symptoms
associated with seasonal allergic rhinitis and chronic idiopathic
urticaria. On June 18, 1999, Janssen withdrew Hismanal tablets from
sale in the United States. The agency's review of the withdrawal of
astemizole 10-mg tablets (Hismanal) from the market has considered the
sponsor's explanation of the basis for the withdrawal of the product
and information available to the agency regarding Hismanal. The current
evidence supports the conclusion under Sec. 314.161 (21 CFR 314.161)
that astemizole 10-mg tablets (Hismanal) were withdrawn from the market
for safety reasons.
The agency has determined, under Sec. 314.161, that astemizole 10-
mg tablets (Hismanal) were withdrawn from the market for safety
reasons. Accordingly, the agency will remove astemizole 10-mg tablets
(Hismanal) from the ``Orange Book'' (Sec. 314.162). FDA will not accept
or approve ANDA's that refer to this drug product.
Dated: August 13, 1999.
Margaret M. Dotzel,
Acting Associate Commissioner for Policy.
