4. CLINICAL PARTICULARS

4.1 Target species

Calves

4.2 Indications for use, specifying the target species

Is indicated as an oral rehydration therapy for the treatment of diarrhoea in calves by reversing the process of dehydration, acidosis and loss of electrolytes associated with diarrhoea, whether caused by bacteria, viruses, cryptosporidia or inappropriate nutrition.

4.3 Contraindications

None.

4.4 Special warnings for each target species

None.

4.5 Special precautions for use

i. Special precautions for use in animals

None.

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

None.

4.6 Adverse reactions (frequency and seriousness)

None known.

4.7 Use during pregnancy, lactation or lay

Not applicable.

4.8 Interaction with other medicinal products and other forms of interaction

None known.

The product has been shown to be compatible with oral antibiotics such as amoxicillin, ampicillin and oxytetracycline.

4.9 Amounts to be administered and administration route

For oral administration only.

The contents of sachets A and B should be added to 2 litres (approximately 3.5 pints) of fresh water, at a temperature of about 35^°C.

Scouring calves

Immediately scour symptoms show, withdraw milk or milk replacer and offer 2 litres of solution twice daily for two days (four feeds). For the next four feeds offer 1 litre of product solution added to 1 litre of milk or milk replacer. Thereafter feed as normal.

Duration of treatment

If the scouring is established or severe, thus causing serious dehydration, the solution should be fed three or four times daily. The product may be used on its own for a maximum of four days.

Ensure that adequate colostrums is fed to all calves.

General recommendations

Keep feeding utensils clean.

Any medicated water which is not consumed within 24 hours should be discarded.

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

No adverse effects are to be expected from an accidental overdose.

4.11 Withdrawal period(s) Meat: Zero days.

5. PHARMACOLOGICAL PROPERTIES

A glucose-glycine-electrolyte formulation which is effective in oral rehydration therapy. The underlying principles of this are:

1. Intestinal absorption of glucose and amino acids is an active process linked to the movement of sodium and water.

2. The linked absorption increases net fluid and electrolyte uptake and offsets fluid loss, so reversing the process of dehydration and diarrhoea; 3. When diarrhoea is caused by bacterial enteroxtoxins, the active transport of glucose and glycine is not impaired;

Diarrhoea may result in dehydration, hyponatraemia, hyperkalaemia and acidosis. Effective oral rehydration therapy will reverse the net secretion of fluid and electrolytes into the gut and promote net absorption of water, electrolytes and nutrients. The active ingredients of the product act in this way. Glucose and glycine are actively absorbed by a sodium-dependent mechanism, bringing about a net uptake of water. In addition, these ingredients also act as a source of energy (glucose) and amino acids (glycine). This increased content of energy and amino acid is particularly important for the calf when milk is withheld during the treatment regime.

Sodium and chloride ions from the salt form an essential part of the sodiumdependent glucose and glycine transport mechanism, which promotes the absorption of water. Potassium dihydrogen phosphate provides potassium, phosphate and hydrogen ions, helping to restore electrolyte balance. Citrate ions further enhance water uptake from the gut and indirectly provide bicarbonate to correct the acidosis of dehydration and diarrhoea. The product has extra citrate ions which aid this process. When made up with water as directed, the product forms an isotonic solution. This is beneficial, as a hypertonic solution would promote further water secretion into the gut, so exacerbating the diarrhoea.
