3. PHARMACEUTICAL FORM


Solution for injection.

Clear, pale yellow aqueous solution.


4. CLINICAL PARTICULARS


4.1 Target species


Horse


4.2 Indications for use, specifying the target species


For treatment of lameness in horses due to traumatic or degenerative aseptic joint disease.


4.3 Contraindications


Do not use in animals with infected or actively inflamed joints or with severe degradation of joint cartilage.

Do not use in animals with known sensitivity to the active ingredient.

Do not use in cases of advanced renal or hepatic disease.

Do not use in pregnant animals.


4.4 Special warnings for each target species


None.


4.5 Special precautions for use


i. Special precautions for use in animals


In the presence of an active joint inflammation, therapy with a suitable anti-inflammatory agent should be given prior to intra-articular treatment with Adequan. The anti-inflammatory treatment should be discontinued as soon as possible since steroidal and non-steroidal agents may contribute to the degeneration of cartilage.


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


Care should be taken to avoid accidental self-injection.

In the case of accidental eye or skin contact, wash the affected area thoroughly with copious amounts of water. If irritation persists, seek medical attention.


4.6 Adverse reactions (frequency and seriousness)


After intra-articular injection, reactions in the joint, including joint oedema, may occur after the first injection and occasionally after further injections.

Should an acute inflammation occur, postpone further injections.

If signs or symptoms of hypersensitivity occur, the treatment must be discontinued.


4.7 Use during pregnancy, lactation or lay


Do not use during pregnancy.


4.8 Interaction with other medicinal products and other forms of interaction


The product may potentiate the action of anticoagulant preparations.


4.9 Amount to be administered and administration route


For intra-articular use only.


Avoid the introduction of contamination during use.


Inject the contents of 1ml ampoule (250 mg/ml) into the affected joint once a week for 5 weeks. The joint area must be shaved, cleansed and sterilized, as for a surgical procedure, to prevent joint infection.


4.10 Overdose (symptoms, emergency procedures, antidotes)


In the case of overdosage, blood coagulation time, as measured by activated partial thromboplastin time, may be prolonged for a few hours after the injection.


4.11 Withdrawal period


Meat and offal: Zero days.


5. PHARMACOLOGICAL PROPERTIES


Pharmacotherapeutic group:Antiinflammatory and antirheumatic products, non-steroids.

ATCvet code:QM01AX12


5.1. Pharmacodynamic properties


The active ingredient is a semisynthetic substance, similar to the physiological mucopolysaccharides which are the basic component of cartilage. In healthy joints, the synthesis and degradation of cartilage is in equilibrium. In traumatic and degenerative joint disease, the natural equilibrium between synthesis and degradation of the cartilage is disturbed. This results in an increased degradation which further results in a loss of glycosaminoglycans.


The product inhibits cartilage degrading enzymes (various glycanohydrolases and glycosidases), stimulates the proteoglycan synthesis and hyaluronic acid synthesis and thus increases the viscosity of the synovial fluid.

Various in-vitrostudies and animal models have been employed to investigate the anti-osteoarthritis activities of PSGAG.


The finding, that the development and progression of degenerative joint diseases were inhibited in all species and models tested, indicates that PSGAG will also therapeutically influence degenerative or traumatic joint diseases in horses.


5.2. Pharmacokinetic particulars


Pharmacokinetic studies were carried out in animals (rats and rabbits) and humans with radioactively labelled PSGAG. After intra-articular and intramuscular administration to humans, maximum plasma levels were reached within 30 minutes and decreased by half after 3 to 5 hours.


The intramuscular administration of 125 mg/ml PSGAG to humans indicates that PSGAG has an affinity to cartilage. These levels in cartilage were higher than the values measured in serum or the synovial fluid. While the serum levels decreased within 12 hours, the concentration in cartilage increased up to 24 hours and remained on a plateau at about 5 mg/g up to 48 hours. Organ distribution and metabolism were investigated in rats and rabbits. In the tissues (kidney, liver, spleen, bone marrow), unchanged PSGAG was detected together with partially depolymerised and desulphated metabolites, which were also eliminated in the urine. Less than 1 per cent of PSGAG was eliminated in the faeces.
