Summary

This study creates a registry to collect real-world information on the safety and effectiveness of ambroxol, a common cough medicine, when used at higher doses for Gaucher disease or GBA-related Parkinson disease. Researchers aim to gather data from 300 patients worldwide who are already taking ambroxol off-label. The goal is to provide a reliable reference for patients, families, and doctors considering this treatment.
