Acute Oral Toxicity Study
in Rats (FHSA) FDRL Test Article ID: 84-0909 Sponsor Test
Article ID: Penetron SUMMARY
The above referenced test article was
evaluated for acute oral toxicity in male and female Sprague-Dawley rats. The
test article was administered by gauge to each of ten rats at a level of 5.0
g/kg body weight.
One animal died on day 7 following
administration of the test article. According to 16 CFR 1500, the above
referenced test article is not considered to be toxic and does not require
cautionary labeling.
FDRL Study No.
8375A
Acute Oral Toxicity
Study
Purpose: To determine
the acute oral toxicity of the test article following a single dose by gauge to
male and female Sprague-Dawley rats.
Compliance with
Government Regulations: This study was conducted in accordance with
the regulations for Good Laboratory Practice as described by the FDA (21 CFR
Part 58), 16 CFR 1500.3 and FDRL Standard Operating Procedures. All data and
pertinent records have been retained by FDRL and are available upon request.
Experimental Design:
Animals and Animal Care
Ten young adult Sprague-Dawley rats were obtained from Charles River
Breeding Laboratories, Inc., Wilmington, MA.
All housing and care conformed to the
standards established in the "Guide for the Care and Use of Laboratory Animals"
DHEW Publication No. (NIH) 78-23. Animals were individually housed in wire mesh
bottom cages in environment-controlled rooms and provided food and water ad
libitum.
Procedure After an
acclimation period of at least 5 days, animals were assigned to the test. Food
was withheld the night prior to dosing on the first day of the study, animals
received a single oral dose by gauge of the test article at a level of 5.0 g/kg
body weight.
Observations
Animals were weighed prior to dosing,
at termination of the study or at necropsy. They were observed frequently on the
day of dosing and daily thereafter for a total of 15 days. All external signs of
toxicity or pharmacological effects were noted.
Necropsy
All animals that died during the study
were subjected to a gross necropsy and abnormalities were recorded.
FDRL Study No.

Appendix II Labeling
Requirements Labeling Requirements* Acute Oral
Toxicity
If 50% or more of the animals die when
given a single dose of 50 mg/kg or less, then the test article is considered
"highly toxic" and appropriate cautionary labeling is required.
If 50% or more of the animals die when
given a single dose greater than 50 mg/kg up to and including 5.0 gms/kg, then
the test article is considered "toxic" and appropriate cautionary labeling is
required.
If less than 50% of the animals die
when given a single dose of 5 grams/kg or greater, then the test article is not
considered to be toxic and does not require cautionary labeling.
As defined in 16 CFR 1500.3
This final report was reviewed as
required by Good Laboratory Practice Regulations for non-clinical laboratory
studies, 21 CFR Part 58 and the study protocol. Inspections were accomplished as
noted, and reported to the study director and inanagement immediately following
their completion. Based on these inspections and the review of the report, this
study was conducted and reported in conformance with the Good Laboratory
Practice regulations.
