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 a supplemental new animal drug application (NADA) filed by Orion Corp. The supplemental NADA provides for veterinary prescription use of dexmedetomidine hydrochloride injectable solution as a sedative and analgesic in cats.

DATES: This rule is effective September 7, 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 a supplement to NADA 141-267 for DEXDOMITOR (dexmedetomidine hydrochloride). The supplemental NADA provides for veterinary prescription use of dexmedetomidine hydrochloride injectable solution as a sedative and analgesic in cats. The supplemental application is approved as of August 15, 2007, and the regulations in 21 CFR 522.558 are amended 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), summaries of the safety and effectiveness data and information submitted to support approval of these applications 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 21 CFR 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)(iii) of the Federal Food, Drug, and Cosmetic Act (the act) (21 U.S.C. 360b(c)(2)(F)(iii)), this approval qualifies for 3 years of marketing exclusivity beginning on the date of approval.

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.
