          - 21 CFR Parts 510 and 520
          - [Docket No. FDA-2010-N-0002]

# AGENCY:

Food and Drug Administration, HHS.

# ACTION:

Final rule.

# SUMMARY:

The Food and Drug Administration (FDA) is amending the animal drug regulations to reflect a change of sponsor for sulfadiazine and pyrimethamine oral suspension from Animal Health Pharmaceuticals, LLC, to Pegasus Laboratories, Inc.

# DATES:

This rule is effective November 15, 2010.

# FOR FURTHER INFORMATION CONTACT:

                        Steven D. Vaughn, Center for Veterinary Medicine (HFV-100), Food and Drug Administration, 7520 Standish Pl., Rockville, MD 20855, 240-276-8300,                         *e-mail: steven.vaughn@fda.hhs.gov.*

# SUPPLEMENTARY INFORMATION:

Animal Health Pharmaceuticals, LLC, 1805 Oak Ridge Circle, suite 101, St. Joseph, MO 64506, has informed FDA that it has transferred ownership of, and all rights and interest in, NADA 141-240 for REBALANCE (sulfadiazine and pyrimethamine) Antiprotozoal Oral Suspension to Pegasus Laboratories, Inc., 8809 Ely Rd., Pensacola, FL 32514. Accordingly, the regulations are amended in 21 CFR 520.2215 to reflect this change of sponsorship.

                    Following this change of sponsorship, Animal Health Pharmaceuticals, LLC, is no longer the sponsor of an approved application. Accordingly, § 510.600 (21                           ( print page 69586)                        CFR 510.600) is being amended to remove the entries for this firm.                

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.
