  • dilates coronary vessels;
  • stimulates the work of the heart muscle;
  • increases coronary blood flow;

To whom is it indicated and when will it cause harm?


The vasodilating properties of the drug improve blood circulation.
Veterinarians prescribe Eufillin if a cat has been diagnosed with chronic and obstructive bronchitis, increased pressure in the vessels of the lungs and impaired cerebral circulation. It is also prescribed for cats with bronchial and cardiac asthma, bronchospasms, and also, if necessary, to relieve cerebral edema, normalize renal blood flow and intracranial pressure. Despite the high effectiveness of the drug Euphyllin, it is not always allowed to be given to cats. Thus, the drug is not used in veterinary practice if the pet has the following pathologies:

  • cardiopalmus;
  • myocardial infarction;
  • epilepsy;

Euphilin is produced in powder for use in veterinary medicine.

, tablets of 0.15 g, ampoules of 1 ml of 24% solution (for intramuscular administration) and 10 ml of 2.4% solution (for intravenous injection).

It is a mixture of theophylline with 1,2-ethylenediamine. The effect of the drug is due to the inhibition of phosphodiesterase and, as a result, an increase in the accumulation of cyclic adenosine monophosphate in tissues. In addition, the drug appears to block adenosine receptors and prevent calcium ions from entering cells.

Eufillin in animals relaxes the muscles of the bronchi, relieving bronchospasm.

Improves blood flow in the heart and kidneys, reduces pulmonary vascular resistance, reducing pressure in the pulmonary circulation. It has a positive inotropic and moderate diuretic effect.

Inhibits the release of allergy mediators from mast cells, stimulates the central nervous system, the respiratory center, and enhances the release of adrenaline by the adrenal glands.

It is recommended to use aminophylline in veterinary medicine for circulatory failure, polyuria, and overdose of cardiac glycosides at a dose of 0.15 ml/kg of a 2.4% solution intravenously slowly with isotonic sodium chloride solution (5-20 ml). If acute respiratory failure, in particular pulmonary edema, is diagnosed, 1-4 ml of a 2.4% aminophylline solution diluted in 5 ml of a 20% glucose solution is slowly injected intravenously. Eufillin is an effective remedy for removing dogs and cats from drug-induced sleep. Small animals are slowly administered intravenously with 0.1 ml/kg of a 2.4% solution of aminophylline with glucose.

When treating dogs with aminophylline with catarrhal bronchopneumonia, especially in severe cases, a jet or drip administration of Ringer's solution to which aminophylline is added is indicated - 5-24 mg/kg. In cases of acute respiratory distress in cats, aminophylline can be used intramuscularly or intravenously at a dose of 2-4 mg/kg.

Animals are also treated with aminophylline as a diuretic for edema of cardiac or renal origin as part of combination therapy.

The administration of aminophylline-containing drugs is contraindicated in cases of sharply low blood pressure, paroxysmal tachycardia, extrasystole, epilepsy and heart rhythm disturbances.

Instructions for use

Dosages of "Eufillin" are calculated by a veterinarian individually for each cat, depending on the condition, characteristics of the course of the disease and its weight.

In most cases, the cat is prescribed medication in the form of injections of 3-5 mg per kilogram of the pet’s weight, 1-2 times a day. The solution is given orally to the cat at a dose of 5-7 mg per 1 kg of body weight, divided into 2-3 doses. For purrs with a severe condition, a microenema is indicated. Typically, the duration of the therapeutic course is 5-7 days; if necessary, the duration of treatment can be increased, but not more than 2 weeks.

Dosage and method of administration

Prescribed, as a rule, intravenously, orally, rarely in the form of microenemas or intramuscularly. At the same time, the doctor calculates the dosage of Eufillin for cats depending on the condition and weight of the animal. Everything is purely individual based on the characteristics of the course of the disease. The following dosages are generally prescribed :

  • Injections - Daily dose of 3-5 mg of active substance per 1 kg of cat's weight, 1-2 times a day.
  • Orally - The daily dose of Euphellin tablets for a cat is 5-7 mg of active ingredient per 1 kg of weight. The calculated amount of the substance is divided into 2-3 doses (morning, lunch, evening).
  • Microenema - Used only in severe cases when the benefit outweighs the risk. In this case, the doctor independently makes a calculation based on the cat’s condition and makes a decision on prescribing a microenema.

Eufillin cannot be injected subcutaneously, as it causes irritation of soft tissues. The course of treatment is on average 5-7 days, but not more than two weeks.

Mechanism of disease development

The disease originates from damage to the bronchial mucosa, producing an irritating and inflammatory effect with the release of fluid, which begins to accumulate in the tissues of the respiratory system. As a result, the mucous membrane succumbs to a strong irritant effect and coughing, swelling appears, and exudate provokes shortness of breath.

What other diseases can be diagnosed when a cat coughs ? Read about this in our article.

During chronic bronchitis, the mucous membrane is completely exposed to the harmful effects of microbes, and along with it, inflammation of the bronchial wall occurs. As a result, muscle fibers are replaced by connective tissue cells, causing the bronchi to lose elasticity and contractile function.

To whom is it indicated and when will it cause harm?

The vasodilating properties of the drug improve blood circulation.

Veterinarians prescribe Eufillin if a cat has been diagnosed with chronic and obstructive bronchitis, increased pressure in the vessels of the lungs and impaired cerebral circulation.

Precautionary measures


Improper administration of the drug is dangerous for the animal's life.
It is possible to achieve a speedy recovery of your pet and eliminate any undesirable consequences only if the medicine is used correctly. So, only a medical worker who knows the rate of administration of the solution should inject a cat with Eufillin, and if it is exceeded, the cat faces death. Therefore, the injection is given slowly, while simultaneously monitoring breathing and the general condition of the purr.

Before the injection, the solution must be warmed to room temperature, taking it out of the refrigerator in advance. It is important to consider that Eufillin is incompatible with drugs that contain fructose, glucose and levulose. You should absolutely not use expired medication for your cat. The shelf life of the medicine is 5 years, provided that the solution is stored in a dry place, protected from light, where the air temperature does not exceed 25 degrees Celsius. Small children and animals should not have access to Eufillin ampoules.
