Summary A 28 day percutaneous
absorption study with FC-98 was conducted
from
October 25, 1979 to December 17, 1979 at Rikez Laboratories, Inc., St. Paul,
Minnesota using male and female albino rabbits ranging in body weights from
1.88 to 2.30 kg. The test article was administered by de-ml application
to ten male and ten female rabbits each a dosage level of 5,000 mg/kg body
weight for a 24 hour exposure period. No mortalities, untoward behavorial
reactions or body weight losses were noted during the 28 day study. Necropsies
were performed on all animals upon termination of the study with no visible
lesions noted. Preliminary serum analysis (see Appendix V) indicates dermal
absorption of FC-98 in albino rabbits, however, due to the limited number
of samples analyzed, no concrete conclusion may be drawn.
Introduction The objective
b of this stud.Y
determine the percutaneous absorption
potential of FC-98 in male and female albino rabbits. The study, which was
initiated at Riker Laboratories, Inc., St. Paul, Minnesota on October 25, 1979
and completed on December 17, 1979, was not conducted to support a government submission or marketing permit and is therefore not regulated by the Good
La.boratory Practice Regulation of 1978. The raw data generated by the Study Director and the final report are stored in the conducting laboratory's
archives.
.E A preliminary rangefinder study was conducted to determinp the appropriate dosage level to be used in this study.

test article. The animals were returned to their cages for a 24 hour period aft(2rwhich time the test article was removed from the dermal surface of the animals. The animals were observed for pharmacotoxic reactions both during
the exposure period (immediately Post dose administration, one and two hours) and after removal of the test article (daily for 14 days following dose administralion)with all ruaclions recorded (Table 3). initial and final body weiglit5were also recorded (Table 1).
The information derived from the initial rangefinder was used in
determining the dosage level for the 28 day percutaneous study. Preparation
of 10 male and 10 female animals for dosing and application of the test article were conducted in the same manner as the rangefinder study with the exception
of the collection of blood samples from the orbital sinus plexus prior to
application and again-on days 1, 7, 14 and 28 after initiation of the study
for serum which was frozen for sponsor analysis. After the 24 hour exposure
