## Abstract

The Food and Drug Administration (FDA) is amending the animal drug regulations to reflect approval of two supplemental new animal drug applications (NADA's) filed by Pfizer, Inc. The supplemental NADA's provide for added use of doramectin in cattle for injectable use for additional persistent efficacy for treatment and control of certain gastrointestinal roundworms and lungworms and for topical use for treatment and control of horn flies.
