End Further Info End Preamble Start Supplemental Information


Med-Pharmex, Inc., 2727 Thompson Creek Rd., Pomona, CA 91767-1861, filed a supplement to ANADA 200-229 that provides for use of TRI-OTIC (gentamicin sulfate, USP; betamethasone valerate, USP; and clotrimazole, USP) Ointment for the treatment of canine otitis externa associated with yeast (Malassezia pachydermatis, formerly Pityrosporum canis) and/or bacteria susceptible to gentamicin. The supplement provides for a new container size, a 15-gram bottle. The supplemental ANADA is approved as of February 27, 2006, and the regulations are amended in § 524.1044g (21 CFR 524.1044g) to reflect the approval. The basis of approval is discussed in the freedom of information summary.

In addition, FDA has noticed that a 215-gram bottle size was approved for this product under ANADA 200-229 but not codified. At this time, that bottle size is being added to § 524.1044g. This action is being taken to improve the accuracy of the regulations.

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 21 CFR 25.33(a)(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.

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.
