The Food and Drug Administration (FDA) is amending the animal drug regulations to reflect approval of a supplemental new animal drug application (NADA) filed by Alpharma, Inc. The supplemental NADA provides for the administration of Type C medicated feeds containing chlortetracycline to cattle as a top dress on feed for the treatment of enteritis and pneumonia.
Alpharma, Inc., One Executive Dr., P.O. Box 1399, Fort Lee, NJ 07024, filed a supplement to NADA 48-761 for AUREOMYCIN 50, 90, or 100 (chlortetracycline) Type A medicated articles. The supplemental NADA provides for the administration of Type C medicated feeds containing chlortetracycline to calves, beef and nonlactating dairy cattle as a top dress on feed to deliver 10 milligrams (mg) chlortetracycline per pound of body weight daily. These medicated feeds are used for the treatment of bacterial enteritis caused by Escherichia coli and Start Printed Page 43249bacterial pneumonia caused by Pasteurella multocida susceptible to chlortetracycline. The supplemental NADA is approved as of January 24, 2002, and the regulations are amended in 21 CFR 558.128 to reflect the approval. The basis of approval is discussed in the freedom of information summary.
Section 558.128 is also being amended to relocate a recently assigned withdrawal time (64 FR 23539, May 3, 1999) to the “Limitations” column of the table describing conditions of use. This is being done to improve the readability of the regulations.
Under section 512(c)(2)(F)(iii) of the Federal Food, Drug, and Cosmetic Act (21 U.S.C. 360b(c)(2)(F)(iii)), this approval for food-producing animals qualifies for 3 years of marketing exclusivity beginning January 24, 2002, because the application contains substantial evidence of the effectiveness of the drug involved, any studies of animal safety or, in the case of food-producing animals, human food safety studies (other than bioequivalence or residue studies) required for the approval and conducted or sponsored by the applicant.
2. Section 558.128 is amended by redesignating paragraphs (a), (b), and (d) as paragraphs (b), (c), and (e), respectively; by adding new paragraphs (a) and (d); and by revising newly redesignated paragraphs (b) and (e) to read as follows:
