Adrenomimetic means. The combined use of ephedrine hydrochloride, epinephrine hydrochloride or norepinephrine hydrotartrate, as well as selective beta-adrenomimetic agents with cardiac glycosides may contribute to the occurrence of cardiac arrhythmia.
Aminazine and other phenothiazine derivatives. The action of cardiac glycosides decreases.
Anticholinesterase drugs. With the simultaneous use of anticholinesterase drugs with cardiac glycosides, bradycardia increases.If necessary, it can be eliminated or weakened by the administration of atropine sulfate.
Glucocorticosteroids. When hypokalemia occurs as a result of prolonged treatment with glucocorticosteroids, an increase in undesirable effects of cardiac glycosides is possible.
Diuretics. When combining diuretic drugs (cause hypokalemia and hypomagnesemia, but increase the concentration of calcium ions in the blood) with cardiac glycosides, the effect of the latter is enhanced. At the same time, the optimal dosing should be followed. You can periodically prescribe potassium-sparing diuretics (spironolactone, triamterene), which eliminate hypokalemia. However, hyponatraemia may develop.
Preparations of potassium. Under the influence of potassium preparations undesirable effects of cardiac glycosides decrease.
Preparations of calcium. In the treatment of cardiac glycosides, parenteral administration of calcium preparations is dangerous, since cardiotoxic effects (cardiac arrhythmias and etc.) are amplified.
Acids of ethylenediaminetetraacetic disodium salt. There is a decrease in the effectiveness and toxicity of cardiac glycosides.
Preparations corticotropin. Action of cardiac glycosides under the influence of corticotropin may increase.
Xanthine derivatives. Preparations of caffeine or theophylline sometimes contribute to the occurrence of cardiac arrhythmias.
Sodium adenosine triphosphate. Do not prescribe sodium adenosine triphosphate concomitantly with cardiac glycosides.
Ergocalciferol. In hypervitaminosis caused by ergocalciferol, it is possible an increase in the action of cardiac glycosides, due to the development of hypercalcemia.
Narcotic analgesics. The combination of fentanyl and cardiac glycosides can cause hypotension.
Naproxen. In healthy people, the joint use of cardiac glycosides with naproxen does not affect the results of psychological testing.
Paracetamol. The clinical significance of this interaction has not been adequately studied, but there are data on the decrease in kidney secretion of cardiac glycosides under the influence of paracetamol.
