Aspirin (Acetylsalicylic Acid)
Aspirin, also known as acetylsalicylic acid (ASA), belongs to the group of non-steroidal anti-inflammatory drugs (NSAIDs) and is commonly used in human medicine as a painkiller, anti-inflammatory, and blood thinner. However, in pets, especially dogs and cats, aspirin can cause severe poisoning. Aspirin poisoning (intoxication) occurs when animals ingest a toxic dose of this active substance.
The mechanism of action of aspirin is based on the inhibition of cyclooxygenase enzymes (COX-1 and COX-2), which are responsible for the formation of prostaglandins. Prostaglandins are endogenous signaling molecules that, among other things, influence inflammatory processes, pain perception, fever, as well as the protection of the gastric mucosa and the regulation of kidney function. By blocking these enzymes, aspirin has pain-relieving, fever-reducing, and anti-inflammatory effects, but at the same time impairs important protective mechanisms in the body.
Particularly noteworthy is the significant difference in aspirin metabolism between dogs and cats. While dogs can metabolize aspirin with a half-life of about 8 hours, cats lack a crucial enzyme for the glucuronidation of salicylic acid, which extends the half-life to about 40 hours. This species-specific peculiarity makes cats particularly susceptible to aspirin poisoning, as the active substance remains in the body significantly longer and can accumulate more easily.
The most important facts at a glance
Aspirin poisoning in dogs and cats represents a medical emergency that requires rapid and targeted veterinary intervention. Aspirin (acetylsalicylic acid) acts by inhibiting cyclooxygenase enzymesEnzymes are biological catalysts that accelerate specific chemical reactions in the body without being consumed. They play a crucial role in virtually all physiological processes., thereby impairing the formation of prostaglandins, which leads to therapeutic effects but also to undesirable side effects.
Particularly noteworthy is the fundamental difference in metabolism between dogs and cats. While dogs can metabolize aspirin with a half-life of about 8 hours, cats lack a crucial enzyme for glucuronidationGlucuronidation is a metabolic process in which glucuronic acid is bound to substances such as drugs, toxins, or hormones to make them more water-soluble and easier to excrete. This process is important for detoxification in the body of dogs and cats., which extends the half-life to about 40 hours. This makes cats particularly susceptible to poisoning.
The most common causes of aspirin poisoning are improper medication administration by pet owners and accidentalAccidental means random or unintentional and refers to events or exposures that are not deliberate, such as the accidental swallowing of foreign objects or toxins by dogs and cats. ingestionIngestion refers to the intake of substances through the mouth and their delivery to the digestive tract. In dogs and cats, the ingestion of toxic substances, foreign objects, or incompatible foods can lead to health problems. of unsecured medications. Symptoms include gastrointestinalGastrointestinal refers to the gastrointestinal tract, a system that extends from the oral cavity to the anus and is responsible for the digestion of food and the absorption of nutrients. complaints (vomiting, diarrheaDiarrhea refers to the condition of frequent, watery bowel movements, which can be a sign of infections, digestive disorders, or other health problems., bleeding), neurological abnormalities (apathyApathy refers to a state of indifference and reduced interest or lack of emotional involvement in activities or events that would normally arouse interest., ataxia, seizures), changes in the respiratoryRespiratory refers to breathing or the process of breathing.

DiagnosisA diagnosis is the identification of a disease or condition by its symptoms and/or results from diagnostic tests. It is the first step in the management and treatment of patients. is based on anamnesis, clinical examination, and laboratory diagnostic procedures, with the direct detection of salicylates in the blood being particularly conclusive. TherapyTherapy refers to the treatment of diseases or disorders with the aim of alleviating symptoms, promoting healing, or improving quality of life. Therapies can be medicinal, surgical, or through other medical interventions. includes decontaminationDecontamination refers to the removal of toxic substances or pathogens from a living being, object, or environment to prevent or treat poisoning or infection., specific antidoteAn antidote is a substance used to neutralize or reverse the harmful effects of poisoning or a drug overdose.

The prognosisThe prognosis is the prediction of the likely course and outcome of a disease based on the general state of health, the nature of the disease, and the response to treatment. It can provide information on how a disease is expected to develop. depends on the dose, the timing of treatment initiation, and pre-existing conditions. With early treatment, it is generally good, whereas with delayed therapyTherapy refers to the treatment of diseases or disorders with the aim of alleviating symptoms, promoting healing, or improving quality of life. Therapies can be medicinal, surgical, or through other medical interventions. or pre-existing organ damage, complications are to be expected. Aftercare includes regular follow-up examinations and, if necessary, dietary measures.
PreventionPrevention includes measures taken to prevent diseases or injuries. In veterinary medicine, this includes vaccinations, parasite control, and health monitoring. measures such as the safe storage of medications and educating pet owners about the dangers of self-medication are crucial to avoid future poisoning cases.
Causes, development and progression
In small doses, aspirin already has an anticoagulantAn anticoagulant is a medication that inhibits blood coagulation, thus preventing the formation of blood clots. It is used for the treatment and prevention of thrombosis and embolism. effect, and in higher doses, due to the inhibition of inflammatory mediators (prostaglandins), it has pain-relieving, fever-reducing, and anti-inflammatory properties.

The causes of aspirin poisoning in pets can be divided into several categories. The most common cause is improper medication administration by pet owners who act with good intentions but administer human medical preparations without veterinary instruction. Many pet owners are unaware of the significant metabolicMetabolic refers to metabolism, i.e. the entirety of chemical processes that take place in a living organism to enable life processes. Metabolic disorders can cause a variety of Diseases in Dogs and cats. differences between humans and animals and mistakenly transfer human dosages or application recommendations to their pets.
Another common cause is the accidentalAccidental means random or unintentional and refers to events or exposures that are not deliberate, such as the accidental swallowing of foreign objects or toxins by dogs and cats. ingestionIngestion refers to the intake of substances through the mouth and their delivery to the digestive tract. In dogs and cats, the ingestion of toxic substances, foreign objects, or incompatible foods can lead to health problems. of aspirin by curious animals who have access to unsecured medications. Dogs, in particular, who are less selective about what they eat, can swallow entire packages of painkillers if they are stored within their reach.

In veterinary medicine, many treatments are administered orally. intake in dogs is approximately 50 mg/kg body weight three times daily, while in cats it is already 25 mg/kg body weight twice daily. The LD50 (dose at which 50% of animals die without treatment) is stated as approximately 700 mg/kg body weight for dogs. For cats, this value is significantly lower.
Mechanism of action
Prostaglandins are involved in regulating stomach acid and blood flow to the gastric mucosaMucosa, also called mucous membrane, refers to the moist lining of body cavities that are connected to the outside world, such as the mouth, nose, lungs, and gastrointestinal tract. It serves to protect and facilitate the absorption of nutrients..

Imbalances can lead to serious health problems..
Aspirin in ointments is also almost completely absorbed through the skin.
Cats react significantly more sensitively. Due to a genetic change, cats of all breeds are hardly able to convert salicylic acid, which is formed immediately after aspirin intake, into a substance that can be excreted via the kidneys.
As a result of this special situation in cats, eliminationElimination refers to the process by which waste products and toxins are removed from the body. This includes excretion via the kidneys (urine), intestines (stool), lungs (breath), and skin. from the body takes about five times longer in cats than in dogs. In dogs, a half-life of 8 hours can be assumed. In cats, it is approximately 40 hours.
This is also the reason why the therapeutic administration of aspirin in dogs is twice daily, while in cats it should only be once daily.

Animals with kidney damage may require a special renal diet and regular monitoring of kidney function.
It is particularly important to educate pet owners about preventive measures to avoid future poisonings. This includes safely storing medications out of reach of pets, ideally in locked cabinets. Medications should never be administered without veterinary instruction, and expired or no longer needed medications must be disposed of properly.
In some cases, animals that have survived severe poisoning may have long-term damage that requires permanent adjustments to their living conditions. This particularly affects animals with permanent kidney function impairments who require lifelong monitoring and treatment.
Research outlook
Research in the field of aspirin poisoning in pets is currently focusing on several promising approaches. One focus is on the development of species-specific antidotes, especially for cats, which are particularly at risk due to their limited metabolicMetabolic refers to metabolism, i.e. the entirety of chemical processes that take place in a living organism to enable life processes. Metabolic disorders can cause a variety of Diseases in Dogs and cats. capacity. Scientists are investigating modified prostaglandinProstaglandins are a group of physiologically active lipid compounds found in almost all tissues and organs. They play an important role in Inflammatory conditions, pain transmission, and the regulation of blood flow and platelet function. analogues that are specifically tailored to the needs and physiological peculiarities of cats.
Another research area deals with improved diagnostic methods.

It is the first step in the management and treatment of patients. in veterinary practice. Such tests would allow for immediate treatment decisions without delay due to laboratory examinations.
Innovative treatment approaches such as extracorporeal toxinA toxin is a poison produced by living cells or organisms that can be harmful to the body upon contact or ingestion. Toxins can originate from bacteria, plants, animals, or fungi. eliminationElimination refers to the process by which waste products and toxins are removed from the body. This includes excretion via the kidneys (urine), intestines (stool), lungs (breath), and skin. are gaining increasing importance. Hemodialysis and hemoperfusion have proven effective in severe cases to remove aspirin from the bloodstream. Current studies are focusing on optimizing these procedures for veterinary medicine and developing portable devices that could also be used in smaller practices.
Research into the long-term consequences of recovered aspirin poisoning is another important field. Longitudinal studies investigate whether and to what extent subclinicalSubclinical refers to a condition or disease that does not yet cause any recognizable symptoms. Subclinical diseases can only be diagnosed by specific tests or examinations. organ damage can occur after acute poisoning and what preventive measures are useful to minimize long-term effects.
