title: Effects of atenolol and propranolol on human performance and subjective feelings.
abstract: In a double-blind, double crossover experiment, 18 healthy young men received over 3-day periods either 100 mg atenolol, 80 mg propranolol, or placebo. The subjects underwent various motor and cognitive tests 18 h after each last dose had been taken. Propranolol significantly increased variability of a choice reaction-time task. Scores on various subjective rating scales showed that propranolol had a larger mood elevating effect than atenolol. Heart rate and blood pressure were significantly reduced 24h after atenolol medication; these effects were absent or reduced after propranolol had been given.
