Determination of trace elements in cardiotonic drugs by neutron activation analysis
- 38 Downloads
Potassium may be intimately involved to the action of cardiac glycosides. Chlorine and potassium also act as diuretics. The elements chlorine, manganese, potassium and sodium are determined by instrumental neutron activation analysis in all the cardiotonic drugs which are currently used in Greece. All the available pharmaceutical forms of these drugs were analysed (pills, injections, water solutions). It has been found that there is a wide variation among the different values for managanese, sodium and chlorine while for potassium values are relatively constant. Results are discussed from the pharmacological point of view. It is proposed to study the role of manganese in cardiotonic drugs as well as the effect of potassium addition in oral pharmaceutical form of cardiotonic drugs in decreasing the toxicity of cardiac glycosides.
