FOR FURTHER INFORMATION CONTACT:

Pamela K. Esposito, Center for Veterinary Medicine (HFV-212), Food and Drug Administration, 7519 Standish Pl., Rockville, MD 20855, 240-276-9067; e-mail: [e-mail].

SUPPLEMENTARY INFORMATION:

The following sponsors have requested that FDA withdraw approval of the seven NADAs listed below because the products are no longer manufactured or marketed:

Sponsor	NADA Number Product (Drug)	21 CFR Cite Affected (Sponsor Drug Labeler Code)
Eon Labs Manufacturing, Inc., 227-15 North Conduit Ave., Laurelton, NY 11413	NADA 65-063, Tetracycline capsules	520.2345a (000185)
	NADA 65-345, Chloramphenicol capsules	520.390b (000185)
G.C. Hanford Manufacturing Co., P.O. Box 1017, Syracuse, NY 13201	NADA 65-465, AQUA-MAST (penicillin G procaine)	526.1696a (010515)
International Nutrition, Inc., 7706 “I” Plaza, Omaha, NE 68127	NADA 95-551, TYLAN 5 Premix (tylosin phosphate)	558.625 (043733)
	NADA 109-688, HYGROMIX 2.4 Premix (hygromycin B)	558.274 (043733)
	NADA 109-816, TYLAN 10 SULFA-G Premix (tylosin phosphate and sulfamethazine)	558.630 (043733)
Pfizer, Inc., 235 East 42d St., New York, NY 10017	NADA 103-758, TERAMIX-10 Premix (oxytetracycline)	Not codified

Following the withdrawal of approval of these NADAs, Eon Labs Manufacturing, Inc., is no longer sponsor of an approved application. Therefore, 21 CFR 510.600(c) is amended to remove entries for this sponsor.

As provided below, the animal drug regulations are amended to reflect the withdrawal of approvals. The regulations for penicillin G procaine intramammary dosage forms (21 CFR 526.1696a) are also amended to correct several errors and to reflect a current format.

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.
