DEPARTMENT OF HEALTH AND HUMAN SERVICES
Food and Drug Administration
21 CFR Parts 520 and 558
Animal Drugs, Feeds, and Related Products; Fenbendazole
AGENCY: Food and Drug Administration, HHS.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The Food and Drug Administration (FDA) is amending the animal
drug regulations to reflect approval of two supplemental new animal
drug applications (NADA's) filed by Hoechst-Roussel Agri-Vet Co. One
supplemental NADA provides for use of fenbendazole granules, the other
provides for use of a fenbendazole Type A medicated article to make
Type C medicated feed, both products for use as dewormers for zoo and
wildlife animals.
EFFECTIVE DATE: July 11, 1994.
FOR FURTHER INFORMATION CONTACT: Marcia K. Larkins, Center for
Veterinary Medicine (HFV-112), Food and Drug Administration, 7500
Standish Pl., Rockville, MD 20855, 301-594-0614.
SUPPLEMENTARY INFORMATION: Hoechst-Roussel Agri-Vet Co., Rt. 202-206,
P.O. Box 2500, Somerville, NJ 08876-1258, filed a supplement to NADA
121-473 that provides for use of fenbendazole 22.2 percent granules to
top dress feed, and a supplement to NADA 131-675 that provides for use
of a fenbendazole Type A medicated article (4 percent, 8 percent, and
20 percent) to make Type C medicated feed. The supplements provide for
using 2.5 to 10 milligrams of fenbendazole per kilogram of body weight
per day for 3 days for removal and control of internal parasites in zoo
and wildlife animals.
Supplemental NADA 121-473 is approved as of May 31, 1994,
supplemental NADA 131-675 is approved as of July 11, 1994, and the
regulations are amended in 21 CFR 520.905b and 558.258 to reflect the
approvals.
Approval of NADA 131-675 is for use of fenbendazole Type A
medicated article to make Type C medicated feed. Fenbendazole is a
Category II drug which, as provided in 21 CFR 558.4, requires an
approved form FDA 1900 for making a Type C medicated feed. Therefore,
use of fenbendazole Type A medicated articles to make Type C medicated
feeds as in NADA 131-675 requires an approved form FDA 1900.
In accordance with the freedom of information provisions of part 20
(21 CFR part 20) and Sec. 514.11(e)(2)(ii) (21 CFR 514.11(e)(2)(ii)), a
summary of safety and effectiveness data and information submitted to
support approval of these applications may be seen in the Dockets
Management Branch (HFA-305), Food and Drug Administration, rm. 1-23,
12420 Parklawn Dr., Rockville, MD 20857, between 9 a.m. to 4 p.m.,
Monday through Friday.
Under section 512(c)(2)(F)(iii) of the Federal Food, Drug, and
Cosmetic Act (21 U.S.C. 360b(c)(2)(F)(iii)), these supplemental
approvals qualify for a 3-year period of marketing exclusivity, for
supplemental NADA 121-473 for this use beginning May 31, 1994, and for
supplemental NADA 131-675 for this use beginning July 11, 1994, because
new clinical or field investigations (other than bioequivalence or
residue studies) conducted by the sponsor were required for the
approvals.
The agency has carefully considered the potential environmental
effects of this action. FDA has concluded that the action will not have
a significant impact on the human environment, and that an
environmental impact statement is not required. The agency's finding of
no significant impact and the evidence supporting that finding,
contained in an environmental assessment, may be seen in the Dockets
Management Branch (address above) between 9 a.m. and 4 p.m., Monday
through Friday.
