21 CFR Part 558
New Animal Drugs for Use in Animal Feeds; Bacitracin Methylene
Disalicylate and Nitarsone
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 a new animal drug application
(NADA) filed by Alpharma Inc. The NADA provides for using approved
bacitracin methylene disalicylate and nitarsone Type A medicated
articles to make combination drug Type C medicated turkey feeds used as
an aid in the prevention of blackhead, and for increased rate of weight
gain and improved feed efficiency.
EFFECTIVE DATE: July 21, 1998.
FOR FURTHER INFORMATION CONTACT: Charles J. Andres, Center for
Veterinary Medicine (HFV-128), Food and Drug Administration, 7500
Standish Pl., Rockville, MD 20855, 301-594-1600.
SUPPLEMENTARY INFORMATION: Alpharma Inc., One Executive Dr., P.O. Box
1399, Fort Lee, NJ 07024, is sponsor of NADA 141-088 that provides for
combining approved BMD (10, 25, 30, 40, 50, 60, or 75 grams
per pound (g/lb) bacitracin methylene disalicylate) and
Histostat (227 g/lb nitarsone) Type A medicated articles to
make Type C medicated feeds for growing turkeys containing 4 to 50 g
per ton bacitracin methylene disalicylate and 0.01875 percent
nitarsone. The Type C medicated turkey feed is used as an aid in the
prevention of blackhead, and for increased rate of weight gain and
improved feed efficiency in growing turkeys. The NADA is approved as of
June 17, 1998, and Secs. 558.76(d)(3) and 558.369(d) (21 CFR
558.76(d)(3) and 558.369(d)) are amended to add new entries to reflect
the approval. The basis for approval is discussed in the freedom of
information summary.
Also, due to enactment of the Generic Animal Drug and Patent Term
Restoration Act in 1988, National Academy of Science/National Research
Council (NAS/NRC) NADA's are no longer approved. Therefore, the text of
Sec. 558.369(c) NAS/NRC status is removed and the paragraph reserved.
In accordance with the freedom of information provisions of 21 CFR
part 20 and 514.11(e)(2)(ii), a summary of safety and effectiveness
data and information submitted to support approval of this application
may be seen in the Dockets Management Branch (HFA-305), Food and Drug
Administration, 5630 Fishers Lane, rm. 1061, Rockville, MD 20852,
between 9 a.m. and 4 p.m., Monday through Friday.
This approval is for use of single ingredient Type A medicated
articles to make combination drug Type C medicated feeds. One
ingredient, nitarsone, is a Category II drug as defined in 21 CFR
558.3(b)(1)(ii). Prior to enactment of the Animal Drug Availability Act
of 1996 (Pub. L. 104-250) (ADAA), an approved medicated feed
application (MFA) was required for feed mills to make Type C medicated
feeds from Category II drugs. The ADAA revised the Federal Food, Drug,
and Cosmetic Act to replace the requirement for MFA's with that for
feed mill licenses. Use of Type A medicated articles to make Type C
medicated feeds as in this NADA is limited to licensed feed mills.
FDA has determined under 21 CFR 25.33(a)(2) that this action is of
a type that does not individually or cumulatively have a significant
effect on the human environment. Therefore, neither an environmental
assessment nor an environmental impact statement is required.
List of Subjects in 21 CFR Part 558
Animal drugs, Animal feeds.
Therefore, under the Federal Food, Drug, and Cosmetic Act and under
authority delegated to the Commissioner of Food and Drugs and
redelegated to the Center for Veterinary Medicine, 21 CFR part 558 is
amended as follows:
