Tertatolol, a new beta-blocker, and propranolol, considered a reference beta-blocker, were given orally (5 and 160 mg slow release, respectively) for 15 days to two groups of patients with essential hypertension in order to compare their effects on renal hemodynamics. Systolic and diastolic blood pressure, heart rate, and erect plasma renin activity fell significantly in both groups while prostaglandin E2 urinary excretion was unchanged. Tertatolol administration produced increases in glomerular filtration rate, as shown by inulin clearance (+8.9%; p = 0.038) and renal plasma flow, as shown by paraaminohippurate clearance (+13.0%; p = 0.007). In contrast, propranolol administration resulted in a slight decrease in glomerular filtration rate (-2.8%; not significant) and a fall in renal plasma flow (-13.4%; p less than 0.001). Comparison between both treatments showed that glomerular filtration rate and renal plasma flow were higher in the patients treated with tertatolol than in those treated with propranolol whereas filtration fraction was lower, which suggests that tertatolol causes a vasodilation of the glomerular afferent arteriole. These results demonstrate that in contrast to propranolol (160 mg), and despite both drugs exhibiting a comparable antihypertensive activity, tertatolol (5 mg) does not alter but even improves renal perfusion in hypertensive patients.
