The aim of our work was to verify the effect of urapidil on membrane ion transport systems. This was a randomized, double-blind, cross-over study which evaluated the clinical and biochemical effects of urapidil (30 mg twice daily in comparison with placebo) in a group of 10 elderly hypertensive patients (3 male, 7 female ranging from 68 to 90 years, mean age 79.2 ± 7.6 years). For the evaluation in fresh erythrocytes of principal ion transport systems (cotransport Na+/K+, countertransport Na +/Li+, Na+/K+ ATPase pump. intracellular Na+ and K+) we used the nystatin technique. We found that urapidil activated the red cell membrane ions cotransport system (basal values: 83.7 ± 50.3 μmol Na+ RBC 1 -1.h-1, after 1 month of urapidil therapy: 181.5 ± 89.3 ILmol Na+ RBC 1-1.h-1) (P
