          - 21 CFR Part 520
          - [Docket No. FDA-2011-N-0003]

# 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 Pegasus Laboratories, Inc. The NADA provides for the veterinary prescription use of phenylpropanolamine hydrochloride chewable tablets for the control of urinary incontinence due to urethral sphincter hypotonus in dogs.

# DATES:

This rule is effective March 19, 2012.

# FOR FURTHER INFORMATION CONTACT:

                        Lisa M. Troutman, Center for Veterinary Medicine (HFV-116), Food and Drug Administration, 7500 Standish Pl., Rockville, MD 20855, 240-276-8322, email:                         *lisa.troutman@fda.hhs.gov.*

# SUPPLEMENTARY INFORMATION:

Pegasus Laboratories, Inc., 8809 Ely Rd., Pensacola, FL 32514, filed NADA 141-324 that provides for the veterinary prescription use of PROIN (phenylpropanolamine hydrochloride) Chewable Tablets for the control of urinary incontinence due to urethral sphincter hypotonus in dogs. The NADA is approved as of August 4, 2011, and the regulations are amended in 21 CFR part 520 to reflect the approval.

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 21 CFR 25.33 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)(i) of the Federal Food, Drug, and Cosmetic Act (21 U.S.C. 360b(c)(2)(F)(i)), this approval qualifies for 5 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.

# List of Subjects in 21 CFR Part 520

      - Animal drugs
