4. Clinical Particulars


4.1 Target species

Dogs and Cats

4.2 Indications for use, specifying the target species


In the dog it is indicated for the control of post-operative pain and inflammation following orthopaedic and soft tissue (including intra-ocular) surgery. In the cat it is indicated for the treatment of post operative pain following surgery.


4.3 Contraindications


Do not administer by intramuscular injection.

Do not exceed the recommended dose or duration of treatment.

Do not administer NSAIDs concurrently or within 24 hours of each other. Some NSAIDs may be highly bound to plasma proteins and compete with other highly bound drugs, which can lead to toxic effects.

Do not use in animals suffering from cardiac, hepatic or renal disease, where there is a possibility of gastrointestinal ulceration or bleeding, or hypersensitivity to the product. As with other NSAIDs there is a risk of rare renal or idiosyncratic hepatic adverse events.

In the absence of any specific studies in pregnant target animals such use is not indicated.


Special Warnings for each target species


Do not use in animals suffering from cardiac, hepatic or renal disease, where there is a possibility of gastrointestinal ulceration or bleeding, or hypersensitivity to the product. As with other NSAIDs there is a risk of rare renal or idiosyncratic hepatic adverse events.

4.5 Special precautions for use


(i) Special precautions for use in animals


Do not use in cats less than 5 months of age. Use in dogs less than 6 weeks of age, or in aged dogs and cats, may involve additional risk. If such use cannot be avoided, such animals may require a reduced dosage and careful clinical management.


Avoid use in any dehydrated, hypovolaemic or hypotensive animal, as there is a potential risk of increased renal toxicity.

Concurrent administration of potential nephrotoxic drugs should be avoided.

NSAIDs can cause inhibition of phagocytosis and hence in the treatment of inflammatory conditions associated with bacterial infection, appropriate concurrent antimicrobial therapy should be instigated.



(ii) Special precautions to be taken by the person administering the veterinary medicinal product to animals


Care should be taken when handling the product to avoid accidental self-injection and skin contact. If skin contact occurs wash any product from the skin immediately. Wash hands after use.



4.6 Adverse reactions (frequency and seriousness)

None Known.


4.7 Use during pregnancy, lactation or lay

In the absence of any specific studies in pregnant target animals such use is not indicated.

4.8 Interaction with other medicinal products and other forms of interaction

Do not administer NSAIDs concurrently or within 24 hours of each other. Some NSAIDs may be highly bound to plasma proteins and compete with other highly bound drugs, which can lead to toxic effects.


Concurrent administration of potential nephrotoxic drugs should be avoided.



4.9 Amounts to be administered and administration route

In the dog, the recommended dosage is 4mg/kg (1ml/12.5kg) bodyweight, by intravenous or subcutaneous injection, best given pre-operatively, either at the time of premedication or induction of anaesthesia.

Clinical trial evidence in dogs suggests that only a single dose of carprofen is required in the first 24 hours peri-operatively; if further analgesia is required within this period, a single half-dose (2mg/kg) of carprofen may be given to dogs as necessary.

In the cat, the recommended dosage is 4mg/kg (0.24ml/3kg) bodyweight as a single dose by subcutaneous or intravenous injection, best given pre-operatively at the time of anaesthesia. In the cat, due to the longer half-life, and narrower therapeutic index, particular care should be taken not to exceed the recommended dose and the use of a 1ml graduated syringe is recommended to measure the dose accurately.


Overdose (symptoms, emergency procedures, antidotes), if necessary


Carprofen is well tolerated up to 3 times the recommended dose for dogs and up to twice the recommended dose for cats.


There is no specific antidote for carprofen overdosage but general supportive therapy as applied to clinical overdosage with NSAIDs should be applied.

5. pharmacological properties



Pharmacotherapeutic group:Antinflammatory & antirheumatic products-

Non –steroids.


ATC Vet Code: QM01AE91


Pharmacodynamic properties



Carprofen (CPF), (±)-6-chloro-a-methylcarbazole-2-acetic acid, is a nonsteroidal anti-inflammatory drug (NSAID) with analgesic and anti-pyretic properties. It is a derivative of phenylpropionic acid and a member of the arylpropionic acid class of NSAIDs. As a representative of the 2-arylpropionic family, it contains a chiral center at C2of the propionic moiety and therefore, exists in 2 sterioisomeric forms, the (+)-S and (-)-R enantiomers.


The mechanism of action of carprofen is unclear, there are two principal theories. One proposes that carprofen is a selective inhibitor of the cyclo-oxygenase isoenzyme, COX-2. The second hypothesis that carprofen is a weak inhibitor of both cyclo-oxygenase isoforms, COX-1 and COX-2, and that it acts, at least partially, by some other unknown mechanism.


Pharmacokinetic properties



Absorption of carprofen is reported to be rapid and complete in the dog. The volume of distribution is small with the highest drug concentrations observed in plasma, which has been ascribed to a high degree of binding to plasma protein. In the cat, following intravenous or subcutaneous administration, the clearance and volume of distribution were greater and elimination half-life was shorter for S(+) carprofen. Bioavailability after subcutaneous dosing was complete.
