[Docket No. FDA-2011-N-0003]


New Animal Drugs; Arsanilate Sodium; Sulfaethoxypyridazine

AGENCY: Food and Drug Administration, HHS.

ACTION: Final rule; correcting amendments.

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

SUMMARY: The Food and Drug Administration (FDA) is amending the animal 
drug regulations to remove sections pertaining to use of arsanilate 
sodium and sulfaethoxypyridazine in medicated feed because there are no 
currently approved new animal drug applications (NADAs) for such uses. 
Conforming amendments are also being made. This action is being taken 
to improve the accuracy of the regulations.

DATES: This rule is effective March 28, 2011.

FOR FURTHER INFORMATION CONTACT: George K. Haibel, Center for 
Veterinary Medicine (HFV-6), Food and Drug Administration, 7519

SUPPLEMENTARY INFORMATION: FDA has determined the animal drug 
regulations describe conditions of use for arsanilate sodium and 
sulfaethoxypyridazine in medicated feed for which no NADA is currently 
approved.
    1. Arsanilate sodium Sec.  558.60 (21 CFR 558.60). In the Federal 
Register of December 18, 1986 (51 FR 45346), FDA proposed to remove 
Sec.  558.20 Drugs used in medicated feeds in use before January 1, 
1958, which are not otherwise listed; interim listing (21 CFR 558.20) 
because this section in part 558 subpart A--General Provisions did not 
provide an appropriate basis upon which to approve medicated feed 
applications and because several of the drugs listed were not the 
subject of approved NADAs. Among other exceptions, FDA proposed to 
transfer the arsanilate sodium provisions of Sec.  558.20 to Sec.  
558.60 in subpart B--Specific New Animal Drugs for Use in Animal Feeds 
(subpart B) to reflect their status as approved conditions of use.
    In 1991, FDA issued a final rule removing most of Sec.  558.20 (56 
FR 19263, April 26, 1991) and codifying approved uses in subpart B. 
Elsewhere in the same issue of the Federal Register, FDA reproposed the 
removal of the remaining portions of Sec.  558.20 that pertained to 
certain uses of arsanilate sodium (56 FR 19332, April 26, 1991). FDA 
reproposed those portions of the rule because it recognized that some 
of the uses it had proposed to codify in subpart B did not appear to be 
the subject of approved NADAs, as previously stated. In the discussion 
of the reproposed changes, FDA tentatively concluded that NADA 8-966 
for arsanilate sodium for use in swine feed was voluntarily withdrawn 
by a letter dated November 12, 1973. The Agency acknowledged this 
withdrawal by a letter dated January 16, 1974 (see 56 FR 19332 at 
19333, Refs. 1 and 2).
    In 1992, FDA issued a final rule removing the remaining portions of 
Sec.  558.20 (57 FR 1641, January 15, 1992) and noted that no evidence 
or comments were received on the 1991 reproposed rule, which had 
requested that anyone claiming to hold an approved NADA for arsanilate 
sodium in swine feed submit evidence to substantiate the approval. FDA 
concluded that NADA 8-966 providing for use of arsanilate sodium in 
medicated feeds for swine was voluntarily withdrawn at the request of 
the sponsor (see 56 FR 19332 and Refs. 1 and 2 of the reproposal).
    After careful review of its NADA records, FDA has concluded that 
all uses of arsanilate sodium in medicated feeds in NADA 8-966 were 
voluntarily withdrawn by the sponsor in 1973 and that there is no 
currently approved NADA providing for the use of arsanilate sodium in 
medicated feed or in any dosage form. Accordingly, the animal drug 
regulations in part 558 (21 CFR part 558) are amended by removing Sec.  
558.60. Conforming amendments are also being made in Sec. Sec.  558.55 
and 558.680 by removing reference to use in combination with amprolium 
and zoalene, respectively. This action is being taken to comply with 
the Federal Food, Drug, and Cosmetic Act (FD&C Act) and to improve the 
accuracy of the regulations.
    2. Sulfaethoxypyridazine (Sec. Sec.  558.579). In 1966, FDA 
approved a food additive petition and codified the safe use of 
sulfaethoxypyridazine in feed and drinking water of swine at Sec.  
121.280 (21 CFR 121.280) (31 FR 2425 at 2426, February 5, 1966). In 
1968, Sec.  121.280 was amended to add use in cattle in feed and water, 
and by tablet and injection, and to make all uses, including use in 
feed restriction to ``for sale by or on the order of a licensed 
veterinarian'' (33 FR 627 at 628, January 18, 1968). A 1969 amendment 
revised that use restriction to read ``for use by or on the order of a 
licensed veterinarian'' (34 FR 20272, December 25, 1969).
    In a 1976 reorganization of certain food additive regulations from 
21 CFR part 121 to new part 558 New Animal Drugs For Use in Animal 
Feed, Sec.  121.280 was redesignated as Sec.  558.579 (41 FR 10983 at 
11005, March 15, 1976). In the intervening 35 years there have been no 
required annual drug experience reports, or any product stability 
reports, submitted for any NADA for use of sulfaethoxypyridazine in 
medicated feed. At this time and after careful review of its NADA 
records, FDA has concluded that that there is no approved NADA for the 
use of sulfaethoxypyridazine in medicated feed for swine or cattle. 
Accordingly, the animal drug regulations in part 558 are amended by 
removing Sec.  558.579. A conforming amendment is also being made in 21 
CFR 522.2240 to remove a provision for administration of 
sulfaethoxypyridazine injectable solution followed by use of 
sulfaethoxypyridazine medicated cattle feed. This action is being taken 
to comply with the FD&C Act and to improve the accuracy of the 
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.''

[[Page 17027]]

Therefore, it is not subject to the congressional review requirements 
in 5 U.S.C. 801-808.
