The effect of digoxin on endothelaemia in rats and its modification by a combination of troxerutin and coumarin.

The effect of digoxin on endothelium was tested with the method based on counting of circulating endothelial cells in rats. Digoxin in low doses had a protective and in high doses a damaging effect on endothelium. The latter effect was effectively suppressed by a concomitant administration of a combination of troxerutin and coumarin (Venalot).
