4.1 Target species

Horse.

4.2 Indications for use, specifying the target species

For sedation of horses.

Do not use in cases of post-traumatic shock or hypovolaemia.

Do not use in animals in a state of severe emotional excitation.

Do not use in animals with epilepsy.

Do not use in pregnant or lactating mares.

Do not use in animals with heart failure.

Do not use in the case of known hypersensitivity to the active substance or any of the excipients of the product. Do not use in neonates.

4.4 Special warnings for each target species

Sedation lasts for approximately six hours, although the actual time and depth of sedation are very dependent on the status of the individual animal.

Increasing the dosage above that recommended results in prolonged action and side effects but no greater sedation.

4.5 Special precautions for use

Special precautions for use in animals

In stallions, the lowest dose range is indicated to minimise prolapse of the penis. The product should be used with caution and with reduced dosage in the case of cardiac or hepatic disease or in debilitated, hypovolemic or anaemic animals.

Acepromazine has negligible analgesic effects. Painful activities should be avoided when handling tranquillized animals.

Tranquillized horses should be kept in a calm place and sensorial stimuli should be avoided as far as possible.

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

Wash hands and exposed skin thoroughly after use.

Persons with sensitive skin or in continuous contact with the product are advised to wear impermeable gloves. Avoid contact with eyes.

If accidental eye contact occurs, flush gently with running water for 15 minutes and seek medical advice if any irritation persists.

In case of accidental ingestion, seek medical advice immediately and show the package leaflet or the label to the physician but, DO NOT DRIVE as sedation can occur.

4.6 Adverse reactions (frequency and seriousness)

The frequency of adverse reactions is defined using the following convention:

- very common (more than 1 in 10 animals treated displaying adverse reaction(s))

- common (more than 1 but less than 10 animals in 100 animals treated)

- uncommon (more than 1 but less than 10 animals in 1,000 animals treated)

- rare (more than 1 but less than 10 animals in 10,000 animals treated)

- very rare (less than 1 animal in 10,000 animals treated, including isolated reports).

Since acepromazine decreases sympathetic nervous system tone, a transient drop in blood pressure may occur after administration.

Inhibition of temperature regulation.

The following reversible changes are possible in the haemogram:

- transient decrease in erythrocyte count and haemoglobin concentration;- transient decrease in thrombocyte and leukocyte counts.

Because it increases prolactin secretion, the administration of acepromazine may lead to disturbances in fertility.

Penile prolapse may occur due to the relaxation of the retractor penis muscles. Retraction of the penis should be visible within two to three hours. If this does not take place, it is advised to contact a veterinary surgeon. Lack of retraction is of particular concern in breeding stallions. Acepromazine has caused paraphimosis sometimes in sequel to priaprism.

In rare cases paradoxical excitation reactions can develop.

Contradictory clinical signs of aggressiveness and generalised CNS stimulation may occur.

Prolapse of the nictitating membrane has also been cited as a possible adverse effect in horses.

4.7 Use during pregnancy, lactation or lay

Acepromazine should not be used in pregnant or lactating mares.

Acepromazine has the potential to induce hypotension in newborns when administered as a premedication for caesarean section in the mare.

Please see also Section 4.6 relating to disturbances in fertility.

4.8 Interaction with other medicinal products and other forms of interaction

Acepromazine potentiates the action of centrally depressant drugs.

Simultaneous administration, or administration to horses recently treated with organophosphates should be avoided, since these molecules enhance the toxic effects of acepromazine. Since acepromazine decreases sympathetic nervous system tone, simultaneous treatment with blood pressure lowering products should not take place. Antacids may cause a decrease in the gastrointestinal absorption of acepromazine after oral administration.

Opiates may enhance the hypotensive effects of acepromazine.

4.9 Amounts to be administered and administration route

For oral administration.

Prefilled syringe

The product is contained within a 10 ml or 15 ml polyethylene syringe. The plunger has a locking ring which should be adjusted to provide the volume required in accordance with the dosage guidelines. 1.0 ml intervals are printed on the syringe plunger, but it is also possible to dose at 0.5 ml intervals.

Before first use of the syringe, turn the locking ring clockwise until aligned with the 0.0 ml mark (side of the ring facing the barrel). Turn the locking ring anti-clockwise will move the ring backwards. Turn the locking ring backwards until the left side of the locking ring lines up with the volume of the oral gel to be administered.

Place the syringe in the animal's mouth and expel the required dose into the cheek pouch.

The gel may also be mixed with food.

Glass bottle

The product is filled into 10, 15, 20, 30 and 50 ml glass bottles with CRC closure and supplied with a 5 ml syringe with a dose graduation allowing accurate dosing of 0.1 or 0.2 ml. Withdraw the appropriate dose from the bottle using the supplied syringe. The syringe is brought into the animal's mouth and the appropriate dose is expelled into the animal's cheek.

The gel may also be mixed with food.

Amount(s) to be administered

Moderate sedation: 0.15 mg acepromazine per kg bodyweight Dosage guidelines:

Bodyweight (kg)	200	300	400	450	500	600
Dose (ml)	1.0	1.5	1.5	2.0	2.5	2.5

The above dosage information is provided as a guideline. The dose may be varied to administer between 0.5 and 1.5 times the above recommendation depending on the level of sedation required, i.e. for mild sedation, administer half the recommended dose and for deeper sedation, administer 1½ times the recommended dose.

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

Overdosage results in an earlier onset of the sedative symptoms and in a prolonged effect. Toxic effects are ataxia, hypotension, hypothermia and central nervous system (extrapyramidal) effects.

Noradrenaline, but not adrenaline, can be used to counteract the cardiovascular effects.

4.11 Withdrawal period(s)

Not authorised for use in horses intended for human consumption.

5. PHARMACOLOGICAL PROPERTIES

Pharmacotherapeutic group: Nervous System. ATC vet code: QN05AA04.

5.1 Pharmacodynamic properties

Acepromazine is a phenothiazine derivative. This group of molecules belongs to the neuroleptics: they depress the central nervous system and exert associated effects on the autonomic system. These effects are due to their interference with different neurotransmitter receptors (dopaminergic, adrenergic) and to their interference with hypothalamic performance. The sedative activity starts within 15 to 30 minutes of treatment and lasts for 6 -7 hours.

The desired effects observed after treatment with acepromazine include a general tranquillizing effect, anti-emetic effect and a slight anti-histaminic effect. There is no analgesic action. The neuroleptic effects are variable between individual animals.

5.2 Pharmacokinetic particulars

Acepromazine is partly absorbed from the gastrointestinal tract. Plasma protein binding is high and it is extensively distributed throughout the body tissues. Plasma levels are usually low. Acepromazine is highly metabolised, with the urine as the main route of excretion.
