21 CFR Part 522

Implantation or Injectable Dosage Form New Animal Drugs; Dexmedetomidine

AGENCY: Food and Drug Administration, HHS.

ACTION: Final rule.

SUMMARY: The Food and Drug Administration (FDA) is amending the animal drug regulations to reflect approval of an original new animal drug application (NADA) filed by Orion Corp. The NADA provides for veterinary prescription use of dexmedetomidine hydrochloride injectable solution as a sedative, analgesic, and preanesthetic in dogs.

DATES: This rule is effective January 4, 2007.

FOR FURTHER INFORMATION CONTACT: Melanie R. Berson, Center for Veterinary Medicine (HFV-110), Food and Drug Administration, 7500 Standish Pl., Rockville, MD 20855, 301-827-7540, e-mail: melanie.berson@fda.hhs.gov.

SUPPLEMENTARY INFORMATION: Orion Corp., Orionintie 1, 02200 Espoo, Finland, filed NADA 141-267 for DEXDOMITOR (dexmedetomidine hydrochloride). The NADA provides for the veterinary prescription use of dexmedetomidine hydrochloride injectable solution as a sedative, analgesic, and preanesthetic in dogs. The application is approved as of December 1, 2006, and 21 CFR part 522 is amended by adding new Sec. 522.558 to reflect the approval.

In accordance with the freedom of information provisions of 21 CFR part 20 and 21 CFR 514.11(e)(2)(ii), a summary of safety and effectiveness data and information submitted to support approval of this application may be seen in the Division of Dockets Management (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 Sec. 25.33(d)(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.

Under section 512(c)(2)(F)(ii) of the Federal Food, Drug, and Cosmetic Act (21 U.S.C. 360b(c)(2)(F)(ii)), this approval qualifies for 3 years of marketing exclusivity beginning December 1, 2006.

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.
