Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study aims to assess the efficacy and safety of linaclotide in patients with overlapping symptoms of both functional dyspepsia (FD) and constipation-predominant irritable bowel syndrome (IBS-C).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

After being informed about the content and risks of the research, all eligible patients giving written informed consent will be randomly allocated in a 2:1 ratio to linaclotide (290μg, once daily) or lactulose (20mL, once daily). Treatment will last consecutively for 4 weeks, and patients' symptoms will be assessed before and after four-week treatment.
