Abstrakt: To study a potential interaction between digoxin and two non-steroid anti-inflammatory drugs, indomethacin (50 mg three times daily) and ibuprofen (600 mg three times daily) were given for 10 days to 10 and 8 patients, respectively, on chronic digoxin treatment. Serum digoxin measured by fluorescence polarisation immunoassay increased significantly (P less than 0.05) during treatment with indomethacin from pre-treatment values of 0.73 +/− 0.34 nmol l-1 (mean +/− s.d.) to a mean value of 1.02 +/− 0.43 nmol l-1, while administration of ibuprofen did not change the steady state serum concentration of digoxin. The result demonstrates that some non-steroidal anti- inflammatory drugs such as indomethacin increase serum digoxin to levels high in the therapeutic range. This should be taken into consideration when co-administering other drugs known to increase the serum concentration of digoxin such as several antiarrhythmics. [ABSTRACT FROM AUTHOR]
