    3 hours

Secondary Outcomes (15)

  • Time to perceptible pain relief (onset of therapeutic effect).

    3 hours

  • Change from baseline in sore throat pain intensity self-ratings at 2.5, 5, 7.5, 10 and 15 min after intake, respectively.

    15 minutes

  • Mean change from baseline in sore throat pain intensity self-ratings based on all assessments up to 15, 30, 60, 120, and 180 min after intake as well as during the second (60+ to 120 min) and third hour (120+ to 180 min) after intake, respectively.

    3 hours

  • Change from baseline in self-ratings of difficulty swallowing at 2.5, 5, 7.5, 10 and 15 min after intake, respectively.

    15 minutes

  • Mean change from baseline in self-ratings of difficulty swallowing based on all assessments up to 15, 30, 60, 120, and 180 min after intake as well as during the second (60+ to 120 min) and third hour (120+ to 180 min) after intake, respectively.
