ACTION: Final rule.

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

SUMMARY: The Food and Drug Administration (FDA) is amending the animal 
drug regulations to reflect approval of two abbreviated new animal drug 
applications (ANADA's) filed by Med-Pharmex, Inc. One ANADA provides

water or as a drench, and the second ANADA provides for the use of the 
oral solution in drinking water or as a drench, for the treatment of 
chickens,

turkeys, and dairy calves, dairy heifers, and beef cattle.

EFFECTIVE DATE: November 5, 1998.

FOR FURTHER INFORMATION CONTACT: Lonnie W. Luther, Center for 
Veterinary Medicine (HFV-102), Food and Drug Administration, 7500 
Standish Pl., Rockville, MD 20855, 301-827-0209.

SUPPLEMENTARY INFORMATION: Med-Pharmex, Inc., 2727 Thompson Creek Rd, 
Pomona, CA 91767-1861, has filed both ANADA 200-238 that provides for 
the use of Sulfasol (sulfadimethoxine) soluble powder, and 
ANADA 200-251 that provides for use of Sulforal 
(sulfadimethoxine) concentrated solution, both for use in drinking 
water or as a drench for the treatment of disease outbreaks as follows: 
Coccidiosis, fowl cholera, and infectious coryza in chickens; 
coccidiosis and fowl cholera in meat-producing turkeys; and shipping 
fever complex and bacterial pneumonia associated with Pasteurella spp. 
sensitive to sulfadimethoxine, and calf diphtheria and foot rot 
associated with Sphaerophorus necrophorus sensitive to sulfadimethoxine 
in dairy calves, dairy heifers, and beef cattle.
    ANADA 200-238 is approved as a generic copy of Pfizer, Inc.'s NADA 
46-285 for Albon (sulfadimethoxine soluble powder). ANADA 
200-238 is approved as of July 28, 1998.
    ANADA 200-251 is approved as a generic copy of Pfizer, Inc.'s NADA 
31-205 for Albon (sulfadimethoxine 12.5% concentrated 
solution). ANADA 200-251 is approved as of August 3, 1998.
     Currently the regulations in Sec. 520.2220a (21 CFR 520.2220a) do 
not specify which sponsors have approval for the oral solution or the 
soluble powder. The section is amended to combine paragraphs (a) and 
(b) to specify the approvals, including the new approvals. The basis 
for approval is discussed in the freedom of information summaries.
     In amending Sec. 520.2220a paragraph (a) is revised, paragraph (b) 
is removed, and paragraphs (c) through (e) are redesignated as 
paragraphs (b) through (d), respectively.
    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 these 
applications 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.
    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.

redelegated to the Center for Veterinary Medicine, 21 CFR part 520 is 
amended as follows:

removing paragraph (b), and by redesignating paragraphs (c) through (e) 
as paragraphs (b) through (d), respectively, to read as follows:
