Core Tip	This is the first prospective randomized controlled trial to evaluate add-on trimebutine maleate as an adjuvant to 14-day bismuth quadruple therapy for Helicobacter pylori eradication. Despite trimebutine’s widespread off-label use, add-on treatment did not reduce treatment-emergent adverse events, improve medication adherence, or increase eradication rates, with point estimates tightly clustered around the null. Although the trial was underpowered owing to early termination, these findings do not support routine adjunctive use of trimebutine and redirect attention toward mucosa- and microbiota-directed strategies with proven benefit.
