The authors studied the variations in the effects of isoprenaline hydrochloride on heart rate (beta 1) and on peripheral blood flow of the upper extremity (beta 2), determined by plethysmography, in a group of 5 men with a mean age of 31 +/- 3 years. The trial was conducted on a single-blind cross-over basis, each subject being infused over 30 min with propranolol (30 microgram/kg), acebutolol (150 microgram/kg) or a placebo (isotonic glucose solution) with at least an 8-day interval between each administration. At the end of the infusion they received isoprenaline (0.01 to 0.075 microgram/kg, in logarithmic progression) every 15 min, for 1 hour. The doses of isoprenaline were injected randomly using a latin square design. The peripheral flow, assessed by the curve of the initial part of the plethysmogram for the first 10 sec, increased with the dose of isoprenaline in the placebo series (Tg alpha = 219.9 log d + 583.4; p less than .01), did not increase in the propranolol series and increased with the dose in the acebutolol series (Tg alpha = 221.5 log d + 567.7; p less than .01); the variations in flow with isoprenaline after placebo and after acebutolol, did not differ significantly. The hear rate increased with the dose of isoprenaline in the placebo series (+55%) although tachycardia was inhibited by propranolol and acebutolol. Under the experimental conditions of this trial, propranolol inhibited beta 1 and beta 2 receptors at the same time, whereas acebutolol inhibited only beta 1 receptors.
