title: Pharmacodynamics and pharmacokinetics of digoxin in the presence of lithium.
abstract: Previous biochemical and clinical data suggest there may be an interaction between digoxin and lithium. The pharmacodynamics and pharmacokinetics of an intravenous infusion of digoxin were studied in six male subjects before and after 2 weeks treatment with lithium carbonate. The effects of lithium on sodium pump activity, intracellular electrolytes and extracellular electrolytes were studied. No significant interaction between digoxin and lithium was found. No significant effects of lithium on sodium pump activity or electrolyte concentrations were found.
