Oral Dosage Form New Animal Drugs; Chlortetracycline Soluble Powder

Краткое содержание

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 the American Cyanamid Co. The supplemental NADA's provide for the safe and effective use of chlortetracycline hydrochloride (CTC HCl) soluble powder in both the drinking water of chickens and turkeys for control of certain bacterial diseases susceptible to CTC, and the drinking water of swine and cattle for control and treatment of certain bacterial diseases susceptible to CTC. The approvals reflect compliance with results of the National Academy of Sciences/National Research Council (NAS/NRC), Drug Efficacy Study Group's (DESI) evaluation of the drugs' effectiveness and FDA's conclusions concerning that evaluation.
