**SUPPLEMENTARY INFORMATION:**
Luitpold Pharmaceuticals, Inc., Animal Health Division, Shirley, NY 11967, filed a supplement to NADA 140-901 for ADEQUAN (polysulfated glycosaminoglycan), an injectable solution approved for use in horses and dogs by veterinary prescription for noninfectious degenerative and/or traumatic joint disease. The supplemental NADA provides for additional vial sizes. The application is approved as of November 10, 2009, and the regulations are amended in 21 CFR 522.1850 to reflect the approval.
Approval of this supplemental NADA did not require review of additional safety or effectiveness data or information. Therefore, a freedom of information summary is not required.
The agency has determined under § 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.
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.
