Clinical particulars
Target species
Indications for use
Induction of emesis.
Do not use in cats.
Do not use in case of depression of the Central Nervous System (CNS).
Do not use in cases of ingestion of caustic agents (acids or alkalis), foamy products, volatile substances, organic solvents and non-blunt objects (e.g. glass).
Do not use in animals which are hypoxic, dyspnoeic, seizuring, in hyperexcitation, extremely weak, ataxic, comatose, lacking normal pharyngeal reflexes, or suffering other marked neurologic impairments that could lead to aspiration pneumonia.
Do not use in cases of circulatory failure, shock and anaesthesia.
Do not use in animals which are previously treated with Dopamine-Antagonists (Neuroleptics).
Do not use in cases of hypersensitivity to the active substance or to any of the excipients.
Special warnings for each target species
Expulsive efforts with or without vomiting are likely to be seen from 2 to 15 minutes after the injection of the product and may last from 2 minutes to 2.5 hours. If emesis is not induced following a single injection, do not repeat the injection as it will not be effective and may provoke clinical signs of toxicity.
Special precautions for use in animals
In dogs with known severe hepatic failure, the benefit/risk balance for use of the product in such animals should be considered by the veterinarian.
Before administering the product, consideration must be given to the time of the ingestion of the substance (in relation to gastric emptying times) and on the suitability of inducing emesis based the type of substance ingested (see also Contraindications).
Special precautions to be taken by the person administering the veterinary medicinal product to animals
This product may cause nausea and somnolence. In case of accidental self–injection, seek medical advice immediately and show the package leaflet or the label to the physician. DO NOT DRIVE, as sedation may occur.
Apomorphine has been shown to have teratogenic effects in laboratory animals and is excreted in breast milk. Pregnant or breast-feeding women should avoid handling the product.
This product may cause hypersensitivity reactions. People with known hypersensitivity to apomorphine or any of the excipients should avoid contact with the veterinary medical product.
If the product comes into contact with the skin or eyes, rinse immediately with water. Wash hands after use.
Adverse reactions
Minor adverse reactions may be observed:
- drowsiness (very common)
- modification of appetite (very common)
- increased salivation (very common)
- mild to moderate pain on injection (very common)
- slight dehydration (common)
- change in cardiac frequency (tachycardia followed by bradycardia (common).
These reactions are transient and may be related to the physiological response to expulsive efforts. Multiple episodes of vomiting may be observed, and vomiting may occur up to several hours after the injection. Apomorphine may lower blood pressure.
The frequency of adverse reactions is defined using the following convention:
- very common (more than 1 in 10 animals treated displaying adverse reactions(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).
Use during pregnancy and lactation
Apomorphine has been shown to have teratogenic effects in rabbits and foetotoxic effects in rats at doses higher than the recommended dose in dogs.
The safety of the veterinary medicinal product has not been established during pregnancy and lactation in dogs.
As apomorphine is excreted in breast milk, when used in lactating females, puppies should be monitored carefully for undesired effects.
Use only accordingly to the benefit/risk assessment by the responsible veterinarian.
Neuroleptics (e.g. chlorpromazine, haloperidol), and anti-emetics (metoclopramide, domperidone) reduce or suppress the emesis induced by the administration of apomorphine.
The administration or the prior ingestion of opiates or barbiturates can induce additive CNS effects and respiratory depression with apomorphine.
Caution is advised when dogs are receiving other dopamine agonists, such as cabergoline, due to possible additive effects such as exacerbation or inhibition of vomiting.
Amounts to be administered and administration route
For single subcutaneous administration only.
0.05-0.1 mg of apomorphine hydrochloride hemihydrate per kg body weight (approximately 0.02-0.03 ml product per kg body weight).
An appropriately graduated syringe must be used to allow accurate administration of the required dose volume. This is particularly important when injecting small volumes. Animals should be accurately weighed to ensure administration of the correct dose.
Do not use if the solution has turned green.
Excessive doses of apomorphine may result in respiratory and/or cardiac depression, CNS stimulation (excitement, seizures) or depression, protracted vomiting, or rarely in restlessness, excitement or even convulsion.
At higher doses apomorphine may also suppress vomiting.
Naloxone may be used to reverse the CNS and respiratory effects of apomorphine.
Anti-emetics such as metoclopramide and maropitant should be considered in case of protracted vomiting.
Pharmacological particulars
Pharmacotherapeutic group: Dopamine agonists
ATCvet code: QN04BC07
Pharmacodynamic properties
Apomorphine is an aporphine derivative of the dibenzoquinoline class and a synthetic derivative of morphine with no analgesic, opiate or addictive properties.
At lower doses apomorphine induces emesis by stimulation of the dopamine D2-receptors in the chemoreceptor trigger zone (CTZ).
Higher doses of apomorphine may suppress vomiting by stimulation of the µ receptors in the vomiting centre of the brain.
Pharmacokinetic properties
After subcutaneous administration apomorphine is rapidly absorbed.
Apomorphine binds extensively to plasma proteins.
Apomorphine is extensively metabolised by the liver into non-active metabolites. The metabolites and very little unchanged apomorphine (<2%) are excreted via the urine. It is also excreted in breast milk.
