Abstract：
:Sixteen hypertensive patients received pindolol (10-45 mg/day); mean +/- SD, 28.75 +/- 15.22) for 3-8 weeks in a placebo-controlled, single-blind, crossover study. Supine and standing blood pressures (BP) were lowered, whereas effective renal plasma flow and glomerular filtration rates (estimated from the clearances of Hippuran and EDTA during oral water loading) did not change consistently. "Blood volume" (calculated from 125I-human serum albumin space and microhaematocrit) increased, with a corresponding reduction in serum albumin but without a change in body weight or "total body water" (T2O space). The results suggest a transfer of water from the interstitial to the intravascular compartment. This was supported by estimates of "extracellular fluid volume" (EDTA space) and "interstitial volume" (EDTA) minus human serum albumin spaces) in 3 subjects. The changes produced in "blood volume" correlated with those in BP. Plasma levels of noradrenaline, renin activity, and aldosterone were reduced, as was renal aldosterone excretion. There was no correlation between the changes produced by pindolol in BP and these hormone levels. Pindolol treatment reduced serum calcium concentration. There was a strong positive correlation between changes in BP and serum calcium and renal calcium excretion.
