title: Evaluating mepindolol in a test model of examination anxiety in students.
abstract: The effect of a single dose of beta-blocker (5 or 10 mg mepindolol) during a written examination was investigated in two double-blind studies (N : 49 and 55 students, respectively). The question was whether the beta-blocker would in comparison to placebo diminish examination anxiety and improve the performance of highly complex tasks, while leaving the performance of less complex tasks unchanged. A reduction in examination anxiety after beta-blocker intake could not be demonstrated with a multi-level test model (which included the parameters self-rated anxiety, motor behaviour, task performance and physiology), although pulse rates were lowered significantly. An improvement in performance could not be observed, while - by the same token - the performance was not impaired by the beta-blocker. A hypothesis according to which a beta-blocker has an anxiolytic effect and improves performance, dependent on the level of habitual examination anxiety, was tested post hoc, but could not be confirmed. Ten of the subjects treated with 10 mg mepindolol, complained of different side effects, including dizziness, fatigue and headache.
