Lack of difference in digoxin urinary excretion with two intravenous infusion rates

Clin Pharmacol Ther. 1981 Sep;30(3):317-20. doi: 10.1038/clpt.1981.166.


Ten normal subjects were given 0.4 mg digoxin intravenously by bolus injection over 3 to 5 min and by constant-rate infusion for 1 hr. Urinary excretion of digoxin over the next 6 days, as measured by radioimmunoassay, was similar after both the rates of intravenous injection. In one subject, who excreted substantial amounts of digoxin reduction products, no difference was apparent in the amount of reduced metabolites excreted. These results are not in agreement with previous reports of an effect of intravenous infusion rate on urinary digoxin excretion.
