in combination with other drugs to include certain other drugs that 
have been approved elsewhere in the animal drug regulations. This 
action is being taken to ensure the accuracy and consistency of the 
regulation because the cross-references were not updated at the time 
the combination drug uses were approved.

EFFECTIVE DATE: April 17, 1998.

Medicine (HFV-6), Food and Drug Administration, 7500 Standish Pl., 
Rockville, MD 20855, 301-594-1739.

SUPPLEMENTARY INFORMATION: In Sec. 558.78(d)(3) (21 CFR 558.78(d)(3)) 
FDA codified a list of combinations in which bacitracin zinc is 
approved for use with certain drugs that have been approved elsewhere 
in 21 CFR part 558. Several cross-references to approved combination 
drug uses were not included in that list. Section 558.78(d)(3) is 
amended to add those cross-references.
