title: [Blood pressure and renin activity in essential hypertension under pindolol].
abstract: 20 essential hypertension patients with diastolic blood pressure of 100-140 mm Hg were treated with increasing doses (15-45 mg/day by mouth) of pindolol for 14 weeks after an initial placebo period of 5 weeks. Systolic and diastolic blood pressure decreased significantly with as little as 15 mg of pindolol (p less than 0.001). No further changes in systolic and diastolic blood pressure were observed when the doses of pindolol were increased. Plasma renin activity (PRA) determined by radioimmunoassay did not change under increasing doses of pindolol. The blood pressure changes did not correlate with initial PRA or with individual changes in PRA under increasing doses with individual changes in PRA under increasing doses of pindolol. These results do not afford evidence for a renin-dependent hypotensive effect of pindolol.
