**SUPPLEMENTARY INFORMATION:**
In accordance with section 512(i) of the Federal Food, Drug, and Cosmetic Act (21 U.S.C. 360b(i)) and 21 CFR 514.105(a) and 514.106(a), FDA is providing notice that in 2001 it approved a supplemental ANADA that was not the subject of a final rule. A final rule was not published because § 524.1193 (21 CFR 524.1193) did not require amendment.
On May 16, 2001, FDA approved a supplement filed by Phoenix Scientific, Inc., 3915 South 48th St. Terrace, St. Joseph, MO 64503, to ANADA 200-219 for PHOENECTIN (ivermectin) Pour-On. The supplemental ANADA provided for topical use of a 0.5 percent ivermectin solution on cattle for control of infections of *Ostertagia ostertagi* , *Haemonchus placei* , *Trichostrongylus axei* , *Oesophagostomum radiatum* , *Cooperia punctata* , and *C. oncophora* for 14 days after treatment. This supplemental approval was based on the expiration of marketing exclusivity granted the pioneer product, Merial, Ltd.'s IVOMEC Pour-On for Cattle, in 1997 (62 FR 38907, July 21, 1997). No new data were submitted. The necessary amendment to § 524.1193 was made in a final rule (66 FR 13236, March 5, 2001) for the approval of another generic copy of the pioneer product.
