Study Details

Brief summary:

This open-label, prospective, single-arm pilot study investigates the use of duloxetine, a central neuromodulator, for improving psychological distress and functional impairment in adults with inflammatory bowel disease (IBD). The study focuses on patient-reported outcomes related to anxiety, depression, and IBD-related disability, aiming to assess feasibility, tolerability, and preliminary efficacy in modulating gut-brain axis symptoms and disease-related functional impairments in life
