Firocoxib Chewable Tablets for Dogs

For oral use in dogs only.

Caution: Federal law restricts this drug to use by or on the order of a licensed veterinarian.

Firocoxib Chewable Tablets for
Dogs belongs to the coxib class of non-narcotic,
non-steroidal anti-inflammatory drugs. Firocoxib is a
white crystalline compound described chemically as
3-(cyclopropylmethoxy)-4-(4-(methylsulfonyl)phenyl)-
5,5-dimethylfuranone. The empirical formula is
C17H20O5S, and the molecular weight is 336.4. The
structural formula is shown below:

The absolute bioavailability of Firocoxib Chewable Tablets for Dogs is approximately 38% when administered as a 5 mg/kg oral dose to fasted adult dogs. Firocoxib is rapidly cleared from the blood via hepatic metabolism and fecal excretion (CLsystemic = ~0.4 L/hr/kg). Despite
a high level of plasma protein binding (96%), firocoxib exhibits a large volume of distribution (Vdλ of total drug = ~4.6 L/kg) and a terminal elimination half life of 7.8 hours (%CV = 30%). The oral drug absorption process is highly variable among subjects. Co-administration of firocoxib with food delays drug absorption (Tmax from 1 to 5 hours) and decreases peak concentrations (Cmax from 1.3 to 0.9 mcg/mL). However, food does not affect the overall oral bioavailability at the recommended dose.

Firocoxib Chewable Tablets for Dogs are indicated for the control of pain and inflammation associated with osteoarthritis and for the control of
post-operative pain and inflammation associated with soft-tissue and orthopedic surgery in dogs.

Always provide the Client Information Sheet with prescription. Carefully consider the potential benefits and risks of Firocoxib Chewable Tablets for Dogs and other treatment options before deciding to use Firocoxib Chewable Tablets for Dogs. Use the lowest effective dose for the shortest duration consistent with individual response. The recommended dosage of Firocoxib Chewable Tablets for Dogs for oral administration in dogs is 2.27 mg/lb (5.0 mg/kg) body weight once daily as needed for osteoarthritis and for 3 days as needed for postoperative pain and inflammation
associated with soft-tissue and orthopedic surgery. The dogs can be treated with Firocoxib Chewable Tablets for Dogs approximately two hours prior to surgery. The tablets are scored and dosage should be calculated in half tablet increments. Firocoxib Chewable Tablets for Dogs can be administered with or without food.

Dogs with known hypersensitivity to firocoxib should not receive Firocoxib Chewable Tablets for Dogs.

Not for use in humans. Keep this and all medications out of the reach of children. Consult a physician in case of accidental ingestion by humans.

Keep Firocoxib Chewable Tablets for Dogs in a secure location out of reach of dogs, cats, and other animals to prevent accidental ingestion or overdose.

For oral use in dogs only. Use of this product at doses above the recommended 2.27 mg/lb (5.0 mg/ kg) in puppies less than seven months of age has been associated with serious adverse reactions, including death (see Animal Safety). Due to tablet sizes and scoring, dogs weighing less than 12.5 lb (5.7 kg) cannot be accurately dosed.

All dogs should undergo a thorough history and physical examination before the initiation of NSAID therapy. Appropriate laboratory testing to establish hematological and serum baseline data is recommended prior to and periodically during administration of any NSAID.

Owners should be advised to observe for signs of potential drug toxicity (see Adverse Reactions and Animal Safety) and be given a Client Information Sheet about Firocoxib Chewable Tablets for Dogs.

To report suspected adverse drug events, for technical assistance or to obtain a copy of the Safety Data Sheet (SDS), contact Pegasus Laboratories, Inc. at 1-800-874-9764 or www.prnpharmacal.com.

For additional information about adverse drug experience reporting for animal drugs, contact FDA at 1-888-FDA-VETS or online at www.fda.gov
reportanimalae.

This product cannot be accurately dosed in dogs less than 12.5 pounds in body weight.

Consider appropriate washout times when switching
from one NSAID to another or when switching from corticosteroid use to NSAID use.

As a class, cyclooxygenase inhibitory NSAIDs
may be associated with renal, gastrointestinal and
hepatic toxicity. Sensitivity to drug-associated
adverse events varies with the individual patient.
Dogs that have experienced adverse reactions from
one NSAID may experience adverse reactions from
another NSAID. Patients at greatest risk for adverse
events are those that are dehydrated, on concomitant
diuretic therapy, or those with existing renal, cardiovascular,
and/or hepatic dysfunction. Concurrent
administration of potentially nephrotoxic drugs
should be carefully approached and monitored.
NSAIDs may inhibit the prostaglandins that maintain
normal homeostatic function. Such anti-prostaglandin
effects may result in clinially significant disease in
patients with underlying or pre-existing disease that
has not been previously diagnosed. Since NSAIDs
possess the potential to produce gastrointestinal
ulceration and/or gastrointestinal perforation,
concomitant use of Firocoxib Chewable Tablets for
Dogs with other anti-inflammatory drugs, such as
NSAIDs or corticosteroids, should be avoided.
The concomitant use of protein bound drugs with
Firocoxib Chewable Tablets for Dogs has not been
studied in dogs. Commonly used protein-bound
drugs include cardiac, anticonvulsant, and behavioral
medications. The influence of concomitant drugs
that may inhibit the metabolism of Firocoxib
Chewable Tablets for Dogs has not been evaluated.
Drug compatibility should be monitored in patients requiring adjunctive therapy.

If additional pain medication is needed after the
daily dose of Firocoxib Chewable Tablets for Dogs, a
non-NSAID class of analgesic may be necessary.

Appropriate monitoring procedures should be
employed during all surgical procedures. Anesthetic
drugs may affect renal perfusion, approach concomitant
use of anesthetics and NSAIDs cautiously. The
use of parenteral fluids during surgery should be
considered to decrease potential renal complications
when using NSAIDs perioperatively.

The safe use of Firocoxib Chewable Tablets for Dogs
in pregnant, lactating or breeding dogs has not been
evaluated.

Osteoarthritis: In controlled field studies, 128
dogs (ages 11 months to 15 years) were evaluated
for safety when given firocoxib chewable tablets at
a dose of 2.27 mg/lb (5.0 mg/kg) orally once daily
for 30 days. The following adverse reactions were
observed. Dogs may have experienced more than
one of the observed adverse reactions during the
study.

Firocoxib chewable tablets were safely used during
field studies concomitantly with other therapies
including vaccines, anthelmintics, and antibiotics.

Soft-tissue Surgery: In controlled field studies
evaluating soft-tissue postoperative pain and inflam-
mation, 258 dogs (ages 10.5 weeks to 16 years)
were evaluated for safety when given firocoxib
chewable tablets at a dose of 2.27 mg/lb (5.0 mg/
kg) orally approximately 2 hours prior to surgery
and once daily thereafter for up to two days. The
following adverse reactions were observed. Dogs
may have experienced more than one of the observed reactions during the study.

Firocoxib Chewable
Tablets for Dogs, like other drugs of its class, is
not free from adverse reactions. Owners should be
advised of the potential for adverse reactions and be
informed of the clinical signs associated with drug
intolerance. Adverse reactions may include vomiting,
diarrhea, decreased appetite, dark or tarry stools,
increased water consumption, increased urination,
pale gums due to anemia, yellowing of gums,
skin or white of the eye due to jaundice, lethargy,
incoordination, seizure, or behavioral changes.

Serious adverse reactions associated with this
drug class can occur without warning and in rare
situations result in death (see Adverse Reactions).
Owners should be advised to discontinue Firocoxib
Chewable Tablets for Dogs and contact their veterinarian
immediately if signs of intolerance are
observed. The vast majority of patients with drug
related adverse reactions have recovered when the
signs are recognized, the drug is withdrawn, and
veterinary care, if appropriate, is initiated. Owners
should be advised of the importance of periodic
follow up for all dogs during administration of
any NSAID.

Mode of action: Firocoxib
Chewable Tablets for Dogs is a cyclooxygenaseinhibiting
(coxib) class, non-narcotic, non-ste-
roidal anti-inflammatory drug (NSAID) with anti-
inflammatory and analgesic properties. There are two
main cyclooxygenase enzymes, COX-1 and COX-2,
and a newly discovered third enzyme, COX-3, which
has yet to be fully characterized.1 Cyclooxygenase-1
(COX-1) is the enzyme responsible for facilitating
constitutive physiologic processes, e.g., platelet
aggregation, gastric mucosal protection, and renal
perfusion.2 It also is constitutively expressed in
the brain, spinal cord, and reproductive tract.3
Cyclooxygenase-2 (COX-2) is responsible for the
synthesis of inflammatory mediators, but it is also
constitutively expressed in the brain, spinal cord
and kidneys.4, 5, 6 Cyclooxygenase-3 (COX-3) is also
constitutively expressed in the canine and human
brain and also the human heart.7 Results from in vitro

studies showed firocoxib to be highly selective for
the COX-2 enzyme when canine blood was exposed
to drug concentrations comparable to those observed
following a once daily 5 mg/kg oral dose in dogs.8
However, the clinical significance of these findings
has not been established.

Two hundred and forty-nine dogs of
various breeds, ranging in age from 11 months to
20 years, and weighing 13 to 175 lbs, were randomly
administered firocoxib or an active control drug in
two field studies. Dogs were assessed for lameness,
pain on manipulation, range of motion, joint swelling,
and overall improvement in a non-inferiority evalua-
tionof firocoxib compared with the active control. At
the study's end, 87% of the owners rated firoxib-
treated dogs as improved. Eighty-eight percent
of dogs treated with firocoxib were also judged
improved by the veterinarians. Dogs treated with
firocoxib showed a level of improvement in veteri-
narian-assessed lameness, pain on palpation, range
of motion, and owner-assessed improvement that
was comparable to the active control. The level of
improvement in firocoxib-treated dogs in limb weight
bearing on the force plate gait analysis assessment
was comparable to the active control.

In a separate field study, two hundred fifty-eight
client-owned dogs of various breeds, ranging in
age from 10.5 weeks to 16 years and weighing from
7 to 168 lbs, were randomly administered firocoxib
or a control (sham-dosed-pilled) for the control of
postoperative pain and inflammation associated with
soft-tissue surgical procedures such as abdominal
surgery (e.g. ovariohysterectomy, abdominal
cryptorchidectomy, splenectomy, cystotomy) or
major external surgeries (e.g. mastectomy, skin
tumor removal ≥8 cm). The study demonstrated
that firocoxib-treated dogs had significantly lower
need for rescue medication than the control
(sham-dosed-pilled) in controlling postoperative
pain and inflammation associated with soft-surgery.

A multi-center field study with 226 client-owned
dogs of various breeds, and ranging in age from 1
to 11.9 years in the firocoxib-treated groups and
0.7 to 17 years in the control group was conducted.
Dogs were randomly assigned to either the firocoxib
or the control (sham-dosed-pilled) group for the
control of postoperative pain and inflammation asso-
ciated with orthopedic surgery. Surgery to repair
a ruptured cruciate ligament included the following
stabilization procedures: fabellar suture and/or
imbrication, fibular head transposition, tibial plateau
leveling osteotomy (TPLO), and ‘over the top’ technique.
The study (n = 220 for effectiveness) demon-
strated that foirocoxib-treated dogs had signifcantly
lower need for rescue medication than the control
(sham-dosed-pilled) in controlling postoperative
pain and inflammation associated with orthopedic
surgery.

Animal Safety: In a target animal safety study,
firocoxib was administered orally to healthy adult
Beagle dogs (eight dogs per group) at 5, 15, and 25
mg/kg (1, 3, and 5 times the recommended total daily
dose) for 180 days. At the indicated dose of 5 mg/
kg, there were no treatment related adverse events.

Decreased appetite, vomiting, and diarrhea were
seen in dogs in all dose groups, including unmedicated
controls, although vomiting and diarrhea were
seen more often in dogs in the 5X dose group.
One dog in the 3X dose group was diagnosed with
juvenile polyarteritis of unknown etiology after
exhibiting recurrent episodes of vomiting and
diarrhea, lethargy, pain, anorexia, ataxia, propriocep-
tive deficits, decreased albumin lavels, decreased
and then elevated platelet counts, increased bleeding
times, and elevated liver enzymes. On histopathologic
examination, a mild ileal ulcer was found in one
5X dog. This dog also had a decreased serum albumin
which returned to normal by study completion. One
control and three 5X dogs had focal areas of inflam-
mation in the pylorus or small intestine. Vacuolization
without inflammatory cell infiltrates was noted in the
thalamic region of the brain in three control, one 3X,
and three 5X dogs. Mean ALP was within the normal
range for all groups but was greater in the 3X and
5X dose groups than in the control group. Transient
decreases in serum albumin were seen in multiple
animals in the 3X and 5X dose groups, and in one
control animal.

In a separate safety study, firocoxib was administered
orally to healthy juvenile (10-13 weeks of age)
Beagle dogs at 5, 15, and 25 mg/kg (1, 3, and 5 times
the recommended total daily dose) for 180 days. At
the indicated (1X) dose of 5 mg/kg, on histopathologic
examination, three out of six dogs had minimal
periportal hepatic fatty change. On histopathologic
examination, one control, one 1X, and two 5X dogs
had diffuse slight hepatic fatty change. These animals
showed no clinical signs and had no liver enzyme
elevations. In the 3X dose group, one dog was
euthanized because of poor clinical condition (Day
63). This dog also had a mildly decreased serum
albumin. At study completion, out of five surviving
and clinically normal 3X dogs, three had minimal periportal
hepatic fatty change. Of twelve dogs in the 5X
dose group, one died (Day 82) and three moribund
dogs were euthanized (Days 38, 78, and 79) because
of anorexia, poor weight gain, depression, and in
one dog, vomiting. One of the euthanized dogs had
ingested a rope toy. Two of these 5X dogs had mildly
elevated liver enzymes. At necropsy all five of the
dogs that died or were euthanized had moderate
periportal or severe panzonal hepatic fatty change;
two had duodenal ulceration; and two had pancreatic
edema. Of two other clinically normal 5X dogs (out
of four euthanized as comparators to the clinically
affected dogs), one had slight and one had moderate
periportal hepatic fatty change. Drug treatment was
discontinued for four dogs in the 5X group. These
dogs survived the remaining 14 weeks of the study.
On average, the dogs in the 3X and 5X dose groups
did not gain as much weight as control dogs. Rate of
weight gain was measured (instead of weight loss)
because these were young growing dogs. Thalamic
vacuolation was seen in three of six dogs in the
3X dose group, five of twelve dogs in te 5X dose
group, and to a lesser degree in two unmedicated
controls. Diarrhea was seen in all dose groups,
including unmedicated controls.

In a separate dose tolerance safety study involving a
total of six dogs (two control dogs and four treated
dogs), firocoxib was administered to four healthy
adult Beagle dogs at 50 mg/kg (ten times the recommended
daily dose) for twenty-two days. All dogs
survived to the end of the study. Three of the four
treated dogs developed small intestinal erosion or
ulceration. Treated dogs that developed small intestinal
erosion or ulceration had a higher incidence of
vomiting, diarrhea, and decreased food consumption
than control dogs. One of these dogs had severe
duodenal ulceration, with hepatic fatty change and
associated vomiting, diarrhea, anorexia, weight
loss, ketonuria, and mild elevations in AST and
ALT. All four treated dogs exhibited progressively
decreasing serum albumin that, with the exception of
one dog that developed hypoalbuminemia, remained
within normal range. Mild weight loss also occurred
in the treated group. One of the two control dogs and
three of the four treated dogs exhibited transient
increases in ALP that remained within normal range.

Store at controlled room temperature
between 20-25°C (68-77°F), excursions permitted
between 15-40°C (59-104°F).
