Effect of Supplement:	This supplement amends the NADA to provide for a 11.5 mg spherical tablet, which is half the concentration of the previously approved 23 mg tablet, for cats.

II. INDICATIONS FOR USE

The 11.5 mg tablet is administered orally to cats 4 pounds and under.

IV & V. SAFETY AND EFFECTIVENESS

The approval of the 11.5 mg tablet did not require safety and effectiveness data. The approval was based on an environmental assessment, labeling, and manufacturing information on containers/closures, dissolution, and stability of the 11.5 mg tablets.

VI. HUMAN SAFETY:

A. Human Food Safety

Data on human safety, pertaining to consumption of drug residues in food, were not required for approval of this supplement. The drug is used in cats, which are non-food animals.

B. Human Safety Relative to Possession, Handling and Administration

The labeling contains adequate directions for use and thus poses no human safety hazard.

VII. AGENCY CONCLUSIONS:

Under the Center's supplemental approval policy (55 FR 46045: codified at 21 CFR 514.106), published November 1, 1990, this is a Category II change because it provides for a new tablet size. The approval of this supplemental new animal drug application is supported by adequate safety and effectiveness data for this new animal drug. Accordingly, this approval did not require a re- evaluation of the safety and effectiveness data in the parent application. Under section 512 (c)(2)(F)(iii) of the Federal Food, Drug, and Cosmetic Act (21 U.S.C. 360b(c)(2)(F), this approval does not qualify for any term of marketing exclusivity because no new clinical or field investigations conducted by the sponsor were essential to the approval of this supplemental NADA.

The expertise of a trained professional is required for a definitive diagnosis, to monitor the results of treatment, and determine the occurrence of adverse effects; therefore, the drug is a prescription product.
