Oral Dosage Form New Animal Drugs; Sulfachlorpyridazine Powder
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 supplemental new animal drug application (NADA) filed by Fort Dodge Animal Health, A Division of
Wyeth Holdings Corp. The supplemental NADA provides for a revised food safety warning statement for oral use of sulfachlorpyridazine in the milk or milk replacer of ruminating calves.
DATES: This rule is effective June 24, 2008.
FOR FURTHER INFORMATION CONTACT: Cindy L. Burnsteel, Center for
Veterinary Medicine (HFV-130), Food and Drug Administration, 7500

SUPPLEMENTARY INFORMATION: Fort Dodge Animal Health, A Division of
Wyeth Holdings Corp., P.O. Box 1339, Fort Dodge, IA 50501, filed a supplement to NADA 33-373 for VETISULID (sulfachlorpyridazine sodium)
Powder, approved for oral use in calves and swine for the treatment of diarrhea caused or complicated by Escherichia coli (colibacillosis).
The supplemental NADA provides for a revised food safety warning statement for oral use of sulfachlorpyridazine in the milk or milk replacer of ruminating calves. The supplemental application is approved as of May 19, 2008, and the regulations are amended in 21 CFR 520.2200b to reflect the approval and a current format.
Approval of this supplemental NADA did not require review of additional safety or effectiveness data or information. Therefore, a freedom of information summary is not required.
The agency has determined under 21 CFR 25.33(a)(1) 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.
This rule does not meet the definition of ``rule'' in 5 U.S.C. 804(3)(A) because it is a rule of ``particular applicability.''
Therefore, it is not subject to the congressional review requirements in 5 U.S.C. 801-808.
