Pharmacodynamic: joint application with potassium-sparing diuretics (triamterene, spironolactone), beta-adrenoblockers, cyclosporine, heparin, angiotensin converting enzyme inhibitors, non-steroidal anti-inflammatory drugs increases the risk of hyperkalemia up to the development of arrhythmia and asystole.
The use of potassium preparations together with glucocorticosteroids eliminates the hypokalemia caused by the latter.
Due to the content of potassium ions, the undesirable effects of cardiac glycosides decrease. Due to the content of magnesium ions reduces the effect of neomycin, polymyxin B, tetracycline and streptomycin.
At simultaneous application the preparation can strengthen the neuromuscular blockade caused by depolarizing muscle relaxants (atrakury bezilatom, decamethonium bromide, suxamethonium (chloride, bromide, iodide)).
Calcitriol increases the content of magnesium ions in the blood plasma; Calcium preparations reduce the effect of magnesium preparations.
Pharmacokinetic: astringents and enveloping agents reduce the absorption of the drug in the gastrointestinal tract (it is necessary to observe a 3-hour interval, between their reception).
