Composition and release form

1 tablet retard (prolonged action) contains theophylline 100 or 250 mg; In a cardboard box 5 blisters for 10 pcs.

Pharmacology

Mode of action - bronchodilating, diuretic, vasodilating, cardiotonic.

Inhibits phosphodiesterase and increases the level of cAMP in cells, competitively blocks adenosine receptors. Affects the intracellular distribution of calcium, reduces the release of histamine and leukotrienes, reduces the synthesis and effects of PG, increases the release of endogenous catecholamines.

Pharmacodynamics

As a result of increased motor activity of the ciliary epithelium of the trachea and bronchi, stimulation of the respiratory center and bronchodilation, it increases and improves alveolar ventilation. Strengthens the contractility of the heart muscle, stimulates the secretory activity of the stomach, increases the tone of the central nervous system, moderately expands pulmonary, renal and coronary vessels. Relaxes the smooth muscles of the digestive tract and biliary tract.

Pharmacokinetics

Well absorbed in the digestive tract. Binding to plasma proteins - 60% (in children and patients with cirrhosis of the liver - 35%). It penetrates the placental barrier into breast milk. Cmax - after 6 hours (in children - 4 hours), T1 / 2 - 10-15 hours. The therapeutic concentration in plasma is 10-20 μg / ml. Metabolised in the liver. It is excreted in the urine (unchanged - about 10%).

Interaction

Cimetidine, allopurinol, cyclosporine, macrolides, oral contraceptives, influenza vaccine - increase the concentration in the plasma; Phenobarbital, phenytoin, xanthine preparations, other inducers of microsomal oxidation - reduce. Strengthens the effect of diuretics, reduces - propranolol, pyrazolone derivatives, probenecid, coumarin anticoagulants.
