21 CFR Part 522
Implantation or Injectable Dosage Form New Animal Drugs;
Atipamezole
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 new animal drug application
(NADA) filed by Pfizer, Inc. The NADA provides for intramuscular use of
atipamezole hydrochloride sterile injectable solution in dogs as a
medetomidine reversing agent.
EFFECTIVE DATE: September 17, 1996.
FOR FURTHER INFORMATION CONTACT: Marcia K. Larkins, Center for
Veterinary Medicine (HFV-112), Food and Drug Administration, 7500
Standish Pl., Rockville, MD 20855, 301-594-0614.
SUPPLEMENTARY INFORMATION: Pfizer, Inc., 235 East 42d St., New York, NY
10017, has filed NADA 141-033, which provides for intramuscular use of
Antisedan (atipamezole hydrochloride) sterile injectable
solution in dogs as a reversing agent for Domitor
(medetomidine). Medetomidine is a sedative and analgesic agent approved
for use in dogs. The NADA is approved as of August 6, 1996, and the
regulations are amended in part 522 (21 CFR part 522) by adding new
Sec. 522.147 to reflect the approval. The basis of approval is
discussed in the freedom of information summary.
In accordance with the freedom of information provisions of part 20
(21 CFR part 20) and Sec. 514.11(e)(2)(ii) (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 Dockets
Management Branch (HFA-305), Food and Drug Administration, 12420
Parklawn Dr., rm. 1-23, Rockville, MD 20857, between 9 a.m. and 4 p.m.,
Monday through Friday.
Under section 512(c)(2)(F)(i) of the Federal Food, Drug, and
Cosmetic Act (the act) (21 U.S.C. 360b(c)(2)(F)(i)), this approval
qualifies for 5 years of marketing exclusivity beginning August 6,
1996, because no active ingredient (including any ester or salt of the
drug)
[[Page 48830]]
has been previously approved in any other application filed under
section 512(b)(1) of the act.
The agency has carefully considered the potential environmental
effects of this action. FDA has concluded that the action will not have
a significant impact on the human environment, and that an
environmental impact statement is not required. The agency's finding of
no significant impact and the evidence supporting that finding,
contained in an environmental assessment, may be seen in the Dockets
Management Branch (address above) between 9 a.m. and 4 p.m., Monday
through Friday.
