Optimising the prescription of Proton Pump Inhibitors - DROPIT: a randomized clinical trial in the Swiss primary care setting

Research question

Proton pump inhibitors (PPIs) are the most common treatment of gastric acid-related disorders, and their use is increasing. It can sometimes happen that these treatments are used for longer than necessary, or at higher than required doses.

The DROPIT study aims to evaluate an intervention to optimise the prescription of PPIs in the Swiss primary care setting.
