DEPARTMENT OF HEALTH AND HUMAN SERVICES
21 CFR Part 558


New Animal Drugs for Use in Animal Feeds; Nicarbazin, Roxarsone, 
and Lincomycin; Nicarbazin and Lincomycin; Nicarbazin and Roxarsone

AGENCY: Food and Drug Administration, HHS.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The Food and Drug Administration (FDA) is amending the animal 
drug regulations to reflect approval of three abbreviated new animal 
drug applications (ANADA's) filed by Planalquimica Industrial Ltda. The 
ANADA's provide for use of single ingredient nicarbazin, roxarsone, and 
lincomycin Type A medicated articles to make combination drug Type C 
medicated broiler feeds containing nicarbazin, roxarsone, and 
lincomycin; nicarbazin and lincomycin; or nicarbazin and roxarsone.

EFFECTIVE DATE: April 2, 1996.

FOR FURTHER INFORMATION CONTACT: James F. McCormack, Center For 
Veterinary Medicine (HFV-128), Food and Drug Administration, 7500 
Standish Pl., Rockville, MD 20855, 301-594-1607.

SUPPLEMENTARY INFORMATION: Planalquimica Industrial Ltda., Rua das 
Magnolias nr. 2405, Jardim das Bandeiras, CEP 13053-120, Campinas, Sao 
Paulo, Brazil, filed the following ANADA's:
    ANADA 200-170: Nicarbazin with roxarsone and lincomycin, for Type C 
medicated feeds, as an aid in preventing outbreaks of cecal (Eimeria 
tenella) and intestinal (E. acervulina, E. maxima, E. necatrix, and E. 
brunetti) coccidiosis; for increased rate of weight gain, in broiler 
chickens;
    ANADA 200-171: Nicarbazin and lincomycin, for Type C medicated 
feeds, as an aid in preventing outbreaks of cecal (E. tenella) and 
intestinal (E. acervulina, E. maxima, E. necatrix, and E. brunetti) 
coccidiosis; for increased rate of weight gain, in broiler chickens;
    ANADA 200-172: Nicarbazin and roxarsone, for Type C medicated 
feeds, as an aid in preventing outbreaks of cecal (E. tenella) and 
intestinal (E. acervulina, E. maxima, E. necatrix, and E. brunetti) 
coccidiosis; for increased rate of weight gain, in broiler chickens.
    The ANADA's provide for use of previously approved single 
ingredient Type A medicated articles to make combination drug Type C 
medicated feeds. Planalquimica's ANADA 200-170 is approved as a generic 
copy of Merck Research Laboratories' NADA 107-997, ANADA 200-171 as a 
generic copy of Merck's NADA 108-116, and ANADA 200-172 as a generic 
copy of Merck's 108-115. The ANADA's are approved as of April 2, 1996, 
and the regulations are amended in 21 CFR 558.366(c) to reflect the 
approvals. The basis for approval is discussed in the freedom of 
information summary.
    These approvals are for use of Type A medicated articles to make 
Type C medicated feeds. Nicarbazin and roxarsone are Catagory II drugs 
which, as provided in 21 CFR 558.4, require an approved Form FDA 1900 
for making a Type C medicated feed. Therefore, use of nicarbazin to 
make combination drug Type C medicated feeds as provided in ANADA 200-
170, 200-171, and 200-172 require an approved Form FDA 1900.
    In accordance with the freedom of information provisions of part 20 
(21 CFR part 20) and Sec. 514.11(e)(2)(ii) (21 CFR 514.11(e)(2)(ii)), a 
summary of safety and effectiveness data and information submitted to 
support approval of these applications may be seen in the Dockets 
Management Branch (HFA-305), Food and Drug Administration, 12420 
Parklawn Dr., rm. 1-23, Rockville, MD 20857, between 9 a.m. and 4 p.m., 
Monday through Friday.
    The agency has determined under 21 CFR 25.24(d)(1)(i) that this 
action is of a type that does not individually or cumulatively have a 
significant effect on the human environment. Therefore, neither an 
environmental assessment nor an environmental impact statement is 
required.

    Therefore, under the Federal Food, Drug, and Cosmetic Act and under
