Eufylline injections Pharmacodynamics
Eufylline injections is a ethylenediamine salt of theophylline (which facilitates solubility and increases absorption). It has a bronchodilator effect, apparently due to a direct relaxing effect on the smooth muscles of the airways and blood vessels of the lungs. It is believed that this effect is caused by selective inhibition of the activity of specific FDEs, which leads to an increase in the intracellular concentration of cAMP. The results of experimental studies in vitro show that the main role seems to be played by type III and type IV isoenzymes. Suppression of the activity of these isoenzymes may also cause some side effects of aminophylline (theophylline), including vomiting, arterial hypotension and tachycardia. Blocks adenosine (purine) receptors, which may be a factor in action on the bronchi.
Reduces airway hyperresponsiveness associated with the late phase of the response induced by inhaling allergens through an unknown mechanism that is not related to FDE inhibition or adenosine blockade. There are reports that aminophylline increases the number and activity of T-suppressors in peripheral blood.
It increases mucociliary clearance, stimulates diaphragm contraction, improves respiratory and intercostal muscle function, stimulates the respiratory center, increases its sensitivity to carbon dioxide, and improves alveolar ventilation, which ultimately leads to a reduction in the severity and frequency of apnea episodes. By normalizing respiratory function, it promotes blood oxygenation and decreases carbon dioxide concentration. Enhances lung ventilation in conditions of hypokalemia.

Euphylline injections has a stimulating effect on heart activity, increases strength and heart rate, increases coronary blood flow and increases myocardial oxygen demand. Reduces the tone of blood vessels (mainly vessels of the brain, skin and kidneys). It has a peripheral venodilator effect, reduces pulmonary vascular resistance, lowers the pressure in the small circle of circulation. Increases renal blood flow, has a moderate diuretic effect. Dilates extrahepatic biliary tracts. Stabilizes membranes of mast cells, inhibits release of mediators of allergic reactions. Inhibits platelet aggregation (inhibits platelet activation factor and PgE2alpha), increases resistance of red blood cells to deformation (improves rheological properties of blood), reduces thrombosis and normalizes microcirculation. It has a tocolytic effect and increases the acidity of gastric juice. In high doses it has epileptogenic effect.
