DESCRIPTION:
Levafen™ (carprofen) Chewable Tablets are a non-steroidal
anti-inflammatory drug
(NSAID) of the propionic acid class that includes ibuprofen, naproxen,
and ketoprofen.
Carprofen is the nonproprietary designation for a substituted
carbazole, 6-chloro-α-
methyl-9_H_-carbazole-2-acetic acid. The empirical formula is C
H
CINO and the
molecular weight 273.72. The chemical structure of carprofen is:
Carprofen is a white, crystalline compound. It is freely soluble in
ethanol, but practically
insoluble in water at 25º C.
CLINICAL PHARMACOLOGY:
Carprofen is a non-narcotic, non-steroidal anti-inflammatory agent
with characteristic
analgesic and antipyretic activity approximately equipotent to

models.
The mechanism of action of carprofen, like that of other NSAIDs, is
believed to be
associated with the inhibition of cyclooxygenase activity. Two unique
cyclooxygenases
have been described in mammals.
The constitutive cyclooxygenase, COX-1,
synthesizes prostaglandins necessary for normal gastrointestinal and
renal function.
The inducible cyclooxygenase, COX-2, generates prostaglandins involved
in
inflammation. Inhibition of COX-1 is thought to be associated with
gastrointestinal and
renal toxicity while inhibition of COX-2 provides anti-inflammatory
activity. The specificity
of a particular NSAID for COX-2 versus COX-1 may vary from species to
species.
In an
_in vitro_ study using canine cell cultures, carprofen demonstrated
selective inhibition of
COX-2 versus COX-1.
Clinical relevance of these data has not been shown. Carprofen
has also been shown to inhibit the release of several prostaglandins
in two inflammatory
cell systems: rat polymorphonuclear leukocyte
