Introduction: The primary treatment aim for irritable bowel syndrome (IBS) is to relieve overall symptoms which can significantly impair the patient’s quality of life (QOL); however, it generally requires a high pill burden that may be improved by administration of combinatorial formulations. Thus, the effectiveness of alverine citrate and simeticone combination (ACS) for global symptom relief for IBS was investigated in this non-interventional study. Patients and Methods: ROME III IBS patients (n = 640; 52.3% male: mean age: 43.6 ± 12.5 years) with abdominal pain and discomfort ≥60 of 0-100 visual analogue scale (VAS) were included in a prospective, multicenter, non-interventional study at 26 Chinese sites from December 2010 to January 2012. Patients received alverine citrate (60 mg) with simeticone (300 mg) (ACS) 3× daily for 4 weeks. Pain/discomfort and bloating/distension were assessed by VAS. Global symptoms and QOL were assessed by 7-point and 5-point Likert scales, respectively. Post-treatment bowel function was assessed by Bristol Stool Form Scale (BSFS) and treatment-related adverse events (AEs) were recorded. Results: Of 640 patients, 540 (84.4%) completed the study, and 100 (15.6%) withdrew. In total, 87.5% reported bloating at baseline. After 4-week ACS treatment, 89.1% reported global symptom improvement. Furthermore, 4-week ACS treatment reduced pain and bloated VAS scores significantly from 78.4 ± 9.9 to 32.1 ± 21.0 and from 63.2 ± 27.2 to 22.6 ± 20.9, respectively (both p < 0.001), decreased diarrhea or constipation occurrence from 67.2% to 10.2% (p < 0.001), and reduced IBS impact on QOL with only 2 treatment-related AEs. Conclusion: Routine clinical administration of ACS for IBS over a 4-week period provides effective relief of IBS symptoms and improves QOL in IBS patients.
