About this study

This observational study aims to explore the effectiveness of hydrotalcite, marketed as Talcid, in alleviating acid-related symptoms that occur due to an acid rebound after discontinuing a non-/no-longer-indicated long-term proton pump inhibitor (PPI) therapy. PPIs are commonly prescribed to reduce stomach acid to alleviate symptoms such as heartburn and for the treatment of, for example, duodenal and stomach ulcers. Discontinuation after prolonged use can lead to a rebound effect where dyspeptic complaints such as heartburn occur once the medication is stopped. This study is conducted in Germany and involves adult participants who have stopped using non-/no-longer-indicated PPIs and are experiencing these rebound symptoms. Hydrotalcite is recommended by physicians as an on-demand treatment for managing acid-related symptoms. The study seeks to gather real-world evidence on its effectiveness, consumer experience, and acceptance to support claims about its use to relieve acid related symptoms due to an acid rebound. Participants will use hydrotalcite as needed (on demand when symptoms occur) over a four-week period, and will record information about symptom relief, the time it takes for relief to occur, and overall satisfaction with the treatment. Additionally, their doctors rate the suitability, tolerability, and effectiveness of the treatment. The primary objective of the study is to assess the effectiveness of hydrotalcite by the number and percentage of patients not havi…
