Theophylline dilates the bronchi, blood vessels (mainly vessels of the brain, skin and kidneys). Reduces pulmonary vascular resistance, lowers blood pressure in the pulmonary circulation. Increases renal blood flow. It has a moderate diuretic effect. Inhibits platelet aggregation. It has a stimulating effect on the respiratory center, increases the frequency and strength of heart contractions.

Drug interactions

Theophylline is not used in conjunction with other xanthine derivatives. In combination with phenobarbital, difenin, rifampicin, isoniazid, Carbamazepine, sulfinpyrazone, phenytoin, there is a decrease in theophylline efficacy, which may require an increase in the used doses of the drug.

When used simultaneously with macrolide antibiotics, Lincomycin, Allopurinol, cimetidine, isoprenaline, beta-blockers, oral contraceptives, epoxacin, and during influenza vaccination, the intensity of action may increase, which may require a decrease in theophylline dose.

Theophylline increases the likelihood of side effects of glucocorticosteroids, mineralocorticosteroids (hypernatremia), agents that stimulate the central nervous system (increases neurotoxicity). The drug inhibits the therapeutic effects of lithium carbonate and beta-blockers.Theophylline potentiates the action of diuretics by increasing glomerular filtration and reducing tubular reabsorption. With caution, theophylline is prescribed simultaneously with anticoagulants. Antidiarrheal drugs and enterosorbents reduce theophylline absorption.
