Efficacy and Safety of FEXUCLUE Tab. In Patients With Acute or Chronic Gastritis

A Prospective, Multi-center, Observational Study on the Efficacy and Safety of FEXUCLUE Tab. In Patients With Acute or Chronic Gastritis

This study aims to evaluate the efficacy of Fexuclue tablets in improving gastrointestinal symptoms based on patient-reported outcomes (PROs), by comparing assessments before and after treatment.

In this observational study, patient-reported data will be collected using an electronic application (e-PRO). The survey on subjective symptoms will be administered twice-once before and once after the administration of Fexuclue tablets. Additionally, a survey on medication convenience will be conducted once at 2 weeks (up to a maximum of 4 weeks) post-administration.

At the same time point (2 to 4 weeks after administration), patients will self-assess their overall improvement through the e-PRO application. Investigators will also evaluate final improvement based on clinical judgment in a real-world setting and record the outcome in the Case Report Form (CRF).
