## Abstract

The Food and Drug Administration (FDA) is amending the animal drug regulations to reflect approval of two new animal drug applications (NADAs) filed by Bayer HealthCare LLC. The NADAs provide for the topical use by veterinary prescription of topical solutions containing imidacloprid and two strengths of moxidectin, one for use on dogs and the other for use on cats, for the prevention of heartworm disease, the treatment of flea infestations, and the treatment and control of several internal parasites.
