  • 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.

  • Description:

    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:

  • Pharmacokinetics:

    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.

  • Indications:

    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.

  • Dosage and Administration:

    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.

  • Contraindications:

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

  • Warnings:

    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.

  • Contact Information:

    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.

  • Precautions:

    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.

  • Adverse Reactions:

  • Information for Dog Owners:

    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.

  • Clinical Pharmacology:

    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.

  • Effectiveness:

    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:

    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.

    Firocoxib Chewable Tablets for Dogs

    Firocoxib Chewable Tablets for Dogs are used for the control of
    pain and inflammation due to osteoarthritis or associated with soft-
    tissue and orthopedic surgery in your dog.

    This summary contains important information about Firocoxib
    Chewable Tablets for Dogs. You should read this information before
    you start giving your dog Firocoxib Chewable Tablets for Dogs
    and review it each time your prescription is refilled. This sheet is
    provided only as a summary and does not take the place of instructions
    from your veterinarian. Talk to your veterinarian if you do not
    understand any of this information or you want to know more about
    Firocoxib Chewable Tablets for Dogs.

    What is Firocoxib Chewable Tablets for Dogs?
    Firocoxib Chewable Tablets for Dogs is a veterinary prescription
    non-steroidal anti-inflammatory drug (NSAID) used to control pain
    and inflammation due to osteoarthritis, or associated with soft-tissue
    and orthopedic surgery in dogs.

    Osteoarthritis is a painful condition caused by “wear and tear” of
    cartilage and other parts of the joints that may result in the following
    changes or signs in your dog:
    • Limping or lameness.
    • Decreased activity or exercise (reluctance to stand, climb stairs,
    jump or run, or difficulty performing these activities).
    • Stiffness or decreased movement of joints.
