DEPARTMENT OF HEALTH AND HUMAN SERVICES
21 CFR Part 558
New Animal Drugs For Use In Animal Feeds; Chlortetracycline,
Sulfathiazole, Penicillin
AGENCY: Food and Drug Administration, HHS.
ACTION: Final rule.
-----------------------------------------------------------------------
[[Page 2415]]
SUMMARY: The Food and Drug Administration (FDA) is amending the animal
drug regulations to reflect approval of a supplemental new animal drug
application (NADA) filed by Fermenta Animal Health Co. The supplement
provides for use of fixed combination Type A medicated articles
containing chlortetracycline, sulfathiazole, and penicillin in making
Type B and C medicated swine feeds for swine from 10 pounds to 6 weeks
post-weaning.
EFFECTIVE DATE: January 26, 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: Fermenta Animal Health Co., 10150 North
Executive Hills Blvd., Kansas City, MO 64153, filed a supplement to
NADA 39-077 CSPTM 250 (20 grams (g) of chlortetracycline (as the
hydrochloride), 20 g of sulfathiazole, and 10 g of penicillin (as
penicillin procaine), per pound) and CSPTM 500 (40 g of
chlortetracycline (as the hydrochloride), 40 g of sulfathiazole, and 20
g of penicillin (as penicillin procaine), per pound). The NADA provides
for use of fixed combination Type A medicated articles to make Type B
and C medicated swine feeds for prestarter, starter, grower, and
finisher rations. The supplement provides for prestarter and starter
rations to be given to swine from 10 pounds of body weight to 6 weeks
postweaning for reduction of incidence of cervical abscesses, treatment
of bacterial enteritis (salmonellosis or necrotic enteritis caused by
Salmonella choleraesuis and vibrionic dysentery), maintenance of weight
gains in the presence of atropic rhinitis, increased rate of weight
gain and improved feed efficiency. The supplement is approved as of
January 26, 1996, and the regulations are amended in Sec. 558.155 (21
CFR 558.155) to reflect the approval. The basis of approval is
discussed in the freedom of information summary.
In addition, the agency is revising the section heading for
Sec. 558.155 to reflect the active ingredients as on the label, i.e.,
that the product is known as chlortetracycline with sulfathiazole and
penicillin, not as chlortetracycline hydrochloride with procaine
penicillin and sulfathiazole. The approvals paragraph does specify the
salts and esters approved for use.
In Sec. 558.155(d) the feed consumption table is removed. The
performance or therapeutic claims of the product are based on ad
libitum consumption and not the minimum desired daily feed intake
consumption values reported in the table. This, together with changes
in weaning weights, renders the table obsolete. Also, the indications
for use are editorially revised to clarify the indications for each
feeding group.
The product, chlortetracycline, sulfathiazole, and penicillin, in
combination in a Type A medicated article, is a new animal drug used to
make Type B and Type C medicated feeds. As provided in Sec. 558.4(b),
the combination drug product is a Category II drug because it requires
a withdrawal period at its lowest continuous use level. Therefore, it
requires an approved Form FDA 1900 for making Type B or Type C
medicated feeds as in approved NADA 39-077 and in Sec. 558.155.
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 this application may be seen in the Dockets
Management Branch (HFA-305), Food and Drug Administration, rm. 1-23,
12420 Parklawn Dr., Rockville, MD 20857, between 9 a.m. and 4 p.m.,
Monday through Friday.
Under section 512(c)(2)(F)(iii) of the Federal Food, Drug, and
Cosmetic Act (21 U.S.C. 360b(c)(2)(F)(iii)), this supplemental approval
does not qualify for marketing exclusivity because the supplement does
not contain reports of new clinical or field investigations (other than
bioequivalence or residue studies) or human food safety studies (other
than bioequivalence or residue studies) essential to the approval and
conducted or sponsored by the applicant.
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.
