What researchers measure

Primary outcomes

  1. Total heartburn relief over 0-60 min

    The total heartburn relief is claculated as sum of the heartburn relief scores based on a 5-point verbal rating scale.

    Time frame: up to 60 minutes

Secondary outcomes

  1. Total heartburn relief 0-30 min after comparison hydrotalcite vs. placebo and vs famotidine

    The total heartburn relief is claculated as sum of the heartburn relief scores based on a 5-point verbal rating scale.

    Time frame: up to 30 min

  2. Total heartburn relief 0-3 h after comparison hydrotalcite vs. placebo and vs famotidine

    The total heartburn relief is claculated as sum of the heartburn relief scores based on a 5-point verbal rating scale.

    Time frame: up to 3 h
