title: Propranolol and skilled human performance.
abstract: In a double-blind crossover experiment 18 young men received on one occasion 6 doses of 40 mg propranolol and in the other placebo. Medication was given at 6 hour intervals. One hr after the last capsule was ingested subjects were measured with various physiological and behavioral tests. At the conclusion of testing mean plasma propranolol concentration was 67.6 ng/ml. Propranolol significantly reduced systolic blood pressure and heart rate. There was an increased variability on one behavioral measure but the results of other tests were not affected. The findings are discussed in terms of therapeutic use of this and other beta-adrenergic receptor blocking agents.
