21 CFR Part 520


Oral Dosage Form New Animal Drugs; Spectinomycin

AGENCY: Food and Drug Administration, HHS.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The Food and Drug Administration (FDA) is amending the animal 
drug regulations to correct an error in the indications for use for 
spectinomycin oral solution in swine. FDA is also amending the 
regulations for other oral dosage forms of spectinomycin to reflect a 
current format. These actions are being taken to improve the accuracy 
and readability of the animal drug regulations.

DATES: This rule is effective February 5, 2008.

FOR FURTHER INFORMATION CONTACT: George K. Haibel, Center for 
Veterinary Medicine (HFV-6), Food and Drug Administration, 7519 
Standish Pl., Rockville, MD 20855, 240-276-9019, e-mail: 
[email protected].

SUPPLEMENTARY INFORMATION: FDA has noticed that the animal drug 
regulations do not reflect the approved indications for use for 
spectinomycin oral solution in swine. At this time, FDA is amending the 
animal drug regulations in Sec.  520.2123c (21 CFR 520.2123c) to 
correct this error. FDA is also amending the regulations in Sec.  
520.2123a for spectinomycin tablets and in Sec.  520.2123b for 
spectinomycin powder to reflect a current format. These actions are 
being taken to improve the accuracy and readability of the animal drug 
regulations.
    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.
