Outcome Measures

Primary Outcomes (2)

  • Acute Stress Measured by Tension

    Tension and nervousness were self-assessed by the participants on a 0 to 100 millimeter (mm) Visual Analogue Scale (VAS) before and after a stress test. The VAS is used to determine the subjective impression of tension and nervousness on a 10 cm bipolar visual scale ranging from 0 = "not at all" to 100 = "highly". The measurements started with first intake of Neurexan or Placebo and were repeated until 100 minutes after the end of the stress test. The total stress was then summarized with the area under the curve (AUC) method.

    -210 minutes to +100 minutes

  • Acute Stress Measured by Nervousness

    Tension and nervousness were self-assessed by the participants on a 0 to 100 millimeter (mm) Visual Analogue Scale (VAS) before and after a stress test. The VAS is used to determine the subjective impression of tension and nervousness on a 10 cm bipolar visual scale ranging from 0 = "not at all" to 100 = "highly". The measurements started with first intake of Neurexan or Placebo and were repeated until 100 minutes after the end of the stress test. The total stress was then summarized with the Area under the curve (AUC) method.

    -210 minutes to +100 minutes

Secondary Outcomes (11)

  • Changes in Saliva Alpha Amylase

    -60 minutes, +15 minutes, +45 minutes, +100 minutes

  • Changes in Saliva Cortisol

    -60 minutes, +15 minutes, +45 minutes, +100 minutes

  • Changes in Plasma Adrenocorticotropic Hormone (ACTH)

    -60 minutes, +15 minutes, +45 minutes, +100 minutes

  • Changes in Plasma Cortisol

    -60 minutes, +15 minutes, +45 minutes, +100 minutes

  • Changes in Plasma Catecholamines (Epinephrine)

    -60 minutes, +15 minutes, +45 minutes, +100 minutes

  • +6 more secondary outcomes
