title: Propranolol in experimentally induced stress.
abstract: The influence of beta-adrenoceptor antagonism on the effects of a single experimental stress was investigated in 12 healthy volunteers, using a double-blind protocol. A single oral dose of 80 mg propranolol reduced the stress-induced increase in heart rate and systolic blood pressure to 49.9 per cent and 8.3 per cent respectively compared to 61.0 per cent and 17.4 per cent with placebo. The rise in diastolic blood pressure was small and unaffected by beta-adrenoceptor blockade. The rise in temperature of the skin of the trunk was significantly reduced by propranolol. The self-rating of anxiety, alertness and concentration by the subjects was unaffected by propranolol.
