[Vascular effects of digitalis in human extremities (author's transl)].

The effect of lanatosid C on the peripheral vascular system was studied in a randomized double-blind cross-over study. 1 mg lanatosid C in saline or a corresponding volume of saline were applied intravenously for 30 min to healthy subjects. A significant drop of 28% in blood flow and an increase of peripheral vascular resistence at rest of 44% during and after the application of the cardiac glycoside could be seen while the placebo effect was minimal.
