4. CLINICAL PARTICULARS
4.1 Target species
4.2 Indications for use,specifying the target species
The product is indicated as an adjunct to antimicrobial therapy to reduce clinical signs in acute infectious respiratory disease and acute mastitis in cattle.
Do not use in animals suffering from cardiac, hepatic or renal impairment.
Do not use in animals suffering from gastro-intestinal ulceration or bleeding.
Do not use where there is evidence of a blood dyscrasia.
Do not use in cases of hypersensitivity to the active substance or to any of the excipients.
4.4 Special warnings
4.5 Special precautions for use
Special precautions for use in animals
Avoid use in any dehydrated, hypovolaemic or hypotensive animal, as there is a potential risk of increased renal toxicity. Concurrent administration of potentially nephrotoxic drugs should be avoided.
Do not exceed the stated dose or the duration of treatment.
Do not administer other NSAID’s concurrently or within 24 hours of each other.
As NSAID therapy can be accompanied by GI or renal impairment, adjunctive fluid therapy should be considered especially in the case of acute mastitis treatment.
Special precautions to be taken by the person administering the veterinary medicinal product to animals
Carprofen, in common with other NSAIDs, has been shown to exhibit photosensitising potential in laboratory studies. Avoid skin contact with the veterinary medicinal product. Should this occur, wash the affected areas immediately.
Take care to avoid accidental self-injection. In the event of accidental self-injection seek medical advice immediately.
4.6 Adverse reactions (frequency and seriousness)
Studies in cattle have shown that a transient local reaction may form at the site of the injection.
4.7 Use during pregnancy, lactation or lay
In the absence of any specific studies in pregnant cattle, use only after a risk/benefit assessment has been performed by the attending veterinary surgeon.
4.8 Interaction with other medicinal products and other forms of interaction
No specific significant drug interactions have been reported for carprofen. During clinical studies in cattle four different antibiotic classes were used, macrolides, tetracyclines, cephalosporins and potentiated penicllins without known interactions. However, in common with other NSAIDs, carprofen should not be administered simultaneously with another veterinary medicinal product of the NSAID or glucocorticoid class. Animals should be carefully monitored if carprofen is administered simultaneously with an anticoagulant.
NSAID’s are highly bound to plasma proteins and may compete with other highly bound drugs, such that concomitant administration may result in toxic effects.
4.9 Amounts to be administered and administration route
Single subcutaneous or intravenous injection at a dosage of 1.4 mg carprofen/ kg body weight (1 ml/35 kg) in combination with antibiotic therapy, as appropriate.
The stopper should not be punctured more than 20 times.
4.10 Overdose (symptoms, emergency procedures, antidotes), if necessary
In clinical studies, no adverse signs were reported after intravenous and subcutaneous administration of up to 5 times the recommended dose.
There is no specific antidote for carprofen overdosage but general supportive therapy, as applied to clinical overdosage with NSAID’s, should be applied.
4.11 Withdrawal period(s)
Meat and offal: 21 days
Milk: Zero hours
5. PHARMACOLOGICAL PROPERTIES
Pharmacotherapeutic group:Anti-inflammatory and Anti-rheumatic products, non-steroids
5.1 Pharmacodynamic properties
Carprofen is a member of the 2-arylpropionic acid group of non-steroidal anti-inflammatory drugs (NSAID’s), and possesses anti-inflammatory, analgesic and antipyretic activity.
Carprofen, like most other NSAID’s is an inhibitor of the enzyme cyclo-oxygenase of the arachidonic acid cascade. However, the inhibition of prostaglandin synthesis by carprofen is slight in relation to its anti-inflammatory and analgesic potency. The precise mode of action is unclear.
Studies have shown that carprofen has potent antipyretic activity and significantly reduces the inflammatory response in lung tissue in cases of acute, pyrexic infectious respiratory disease in cattle. Studies in cattle with experimentally induced acute mastitis have shown that carprofen administered intravenously has potent antipyretic activity and improves heart rate and rumen function.
5.2 Pharmacokinetic particulars
Absorption:Following a single subcutaneous dose of 1.4 mg carprofen/kg the maximum plasma concentration (Cmax) of 15.4 μg/ml was reached after (Tmax) 7-19 hours.
Distribution: The highest carprofen concentrations are found in bile and plasma and more than 98% of carprofen is bound to plasma proteins. Carprofen was well distributed in the tissues with the highest concentrations found in kidney and liver followed by fat and muscle.
Metabolism: Carprofen (parent) is the main component in all tissues. Carprofen (parent compound) is slowly metabolised primarily by ring hydroxylation, hydroxylation at the α-carbon and by conjugation of the carboxylic acid group with glucuronic acid. The 8-hydroxylated metabolite and unmetabolized carprofen predominate in the faeces. Bile samples are comprised of conjugated carprofen.
Elimination: Carprofen has a plasma elimination half-life of 70 hours. Carprofen is primarily excreted in the faeces, indicating that the biliary secretion plays an important role.
